Factors to Consider Before Giving Your Dog Doxycycline

vet giving dog a check up

Doxycycline is often given to dogs suffering from bacterial infections that their immune systems can't fight off all on their own, which means they need certain medication to help out.

The most common infections that this medication helps dogs fight are (according to PetMD):

  • Leptospirosis
  • Toxoplasmosis
  • Mycoplasma
  • Rocky Mountain spotted fever
  • Psittacosis
  • Lyme disease
  • Ehrlichiosis

Doxycycline then prevents the bacteria from growing in your dog's body, hence preventing the spreading and intensifying of the infection they are suffering from.

Safety Warning About Using Doxycycline Hyclate

You should never give your dog any medication all on your own if you don't have your veterinarian's approval to do so.

You might think that Doxycycline will help your canine recover from something they're suffering from, but in reality it might do them much more harm than good.

Or, you might get the dosages all messed up or the duration of treatment all wrong.

So, only administer Doxycycline to your dog under the supervision and approval of an animal health care professional.

Correct Doxycycline Dosage For Dogs

Generally, the dosage recommended for you to give your dog is going to be around 2 to 5 mgs of Doxycycline for every 1 lb of your dog's body weight every 24 hours.

*Please check dosage levels with your veterinarian before administering to your pet

various medication

If, supposedly, you miss giving your pet a timed dose of Doxycycline and you remember to do so not too long after the time to administer it has passed, give your dog the missed dose.

However, if it's almost time for you to give your dog the next dose, then forget about the dose you missed giving your dog, don't try to make up for it and stick with the regular schedule.

Whatever you do, you do not want to give your canine two doses of Doxycycline at once.

Methods of Administering Doxy to Your Dog

Doxycycline can be given to dogs in the following ways:

  • In tablet form ingested orally
  • In liquid form given orally via a syringe

Giving your dog Doxycycline all on its own is likely to make them feel nauseous and start to vomit because of it's very bitter taste, so it's better if you give them their dosages as part of a certain meal/food they're eating.

This way, they won't even notice that they're taking any medicine and the chances of them feeling nauseous will be greatly decreased.

If you choose to give your dog Doxycycline in the tablet form, make sure to have them drink enough water to go along with it.

You can even wrap the medicine in something your pup will enjoy eating (like some peanut butter so they don't notice that they're taking any medicine and just swallow the whole thing down).

Best Practices For Successful Treatment

When your dog's on a course of treatment involving Doxycycline, there are some best practices you're going to want to abide by:

  • Don't give your dog any dairy food during this period, because dairy will decrease their system's capability of proper absorbtion
  • Don't brush your dog's teeth for 2 weeks after you give them their first dose
  • Stick with the complete course of treatment specified to you by your veterinarian: If you stop the treatment early on when you think that your dog is fine and fully recovered, they will only relapse and you'll have to start all over again from square one
  • Don't give your dog any supplements or multivitamins that contain aluminum, calcium, magnesium or zinc 2 hours before or after you give them a dose of Doxycycline

Most Common Doxycycline Side Effects

Dogs can often experience some (or all) of the following side effects with this potent prescription:

  • Nausea
  • Vomiting
  • Diarrhea
  • Difficulty in swallowing solids or liquids
  • Difficulty breathing
  • Confusion
  • Decreased consumption of food
  • Swelling in the face, lips or tongue
  • Loss of hair

If you notice that your dog is displaying any of these side effects, continue with the course of treatment as assigned to you by your veterinarian, but inform them of the side effects your dog is showing immediately so they stay on top of the situation in case any modification needs to be done.

Final Thoughts

There you have it - all of the ins and outs of Doxycycline Hyclate. 

What is your experience with this medication? Let us know your thoughts below! Wishing your pup a quick recovery from their infection 🙂


  1. My dog,105 lb German Shepherd, had a URI and was put on doxycycline. After 3 days of taking his meds the infection mostly gone. The side effects then became a bigger problem! He became lethargic, stopped eating, was vomiting, and truly miserable. My vets office kept telling me to keep giving him this med! I did not, he wouldn’t swallow anything anyway. After another 2 days of not eating and acting strange,he finally started to eat again.
    The medication did treat the infection but the side effects were worse then the infection! Be very careful with this drug if prescribed for any infection for your dog.

    • I just started my GSD on this for Ehrlichosis…..I paid $100…and now am reading all of these stories about the side effects. What was your dogs dosage? I started mine on 1/2 of what was prescribed to watch for anything. But what do I give him for this tick disease? What the alternative? Did you have side effects right away?

    • I just started on the med last night and my dog threw up. He hardly ever throws up. The vet said to just continue giving it to him. I don’t want to continue giving it to him. The medication is to help him with his cough. Help!!

      • I have a 7lb chihuahua prescribed 20mg 2x a day for 6 days for a cough. Vet said cough had to run it’s course and likely could do it without the antibiotic. I have him 1 and 1 half days doses, he quit eating, became lethargic, and just looked sick. It took him 2 days before he was himself -i took him off- and still has cough but he’s happy and eating. I think dogs can be like kids..mom knows best.

      • My three dogs have been vomiting for a while. I suspect that is got to be the HEARTWORM medication they all got.
        The little one is very lethargic off and on.
        Take a look at this web site I found myself. It may help to solve some of your dog’s problems.
        Good luck.

    • Same for my dog. He has 4 days left on it and yesterday he was so lethargic and not eating. I didnt give him the night dose or the dose this am.

    • I dont like it for people it made me sick and my Cocker Soaniel isnt acting right either shes 13 yrs and a ting more confused and lethargic and urinating suddenly in lg amount he gave it for possible allergies shewas having a cough and eye drainage Im stopping it

    • If doxy is too much for them, the vets can you the alternative that suppose to be less side effects:tetracycline

      Give doxy with plenty of food ! That’s a must

    • According to my veterinarian, my dog usually doesn’t have bad reactions to doxycycline, but they did say if the side effects were not good, they could give the drug tetracycline, which supposed to be less side effects and easier on them. I think they give doxycycline because it’s the most powerful killing infections.

      I find given plenty of food with the drug works the best !

    • Fasting did it for my Bassett too. 3 full days of water, minerals, baking soda and intervals of probiotics and coloidal silver and she went from a 10 to 100:)

  2. I just started my GSD on this medication for Ehrlichosis. I paid $100 and now I am reading all of these stories of side effects! I started him on 1/2 the dosage to watch for anything. Did the side effects start early? What is my alternative medication?

      • I just started on the med last night and my dog threw up. He hardly ever throws up. The vet said to just continue giving it to him. I don’t want to continue giving it to him. The medication is to help him with his cough. Help!!

        • Stop the meds. After 2 days on doxy my dog has had severe side effects. Has not eaten in 4 days. I will NEVER use this drug again!!!! His prognosis is uncertain.

  3. My beagle is 12 weeks old I’m so very worried about the development of his teethe any professionals on this situation treatment for pneumonia two weeks 100mg oral with syringe thankyou

  4. My 12 y.o Rat Terrier was rescued 9 years ago and suffers from recurring erlichia. The warning signs are clear, low energy and just not acting right. This, on top of the spleen enlargement is very upsetting.
    The doxy has been tolerated and I continue to move through the course. The worst part is seeing my friend lay around on the tile or the bed so uninterested in normality. We hope to see some improvement, I am nervous constantly.

    • My 8 year old Japanese spitz/Terrier mix is on doxy for ehrlichiosis as well. he has low energy and sleeps most of the time at first. but he has a good appetite and has more energy after a few days as the vet also prescribed vitamin b complex to him too.

  5. My pit has heart worms he is on 200mg daily I’m very nervous.he has not been acting the same he hardly eats he acts confused ,lazy like he can’t hear us when we come in he doesn’t act excited to see us and his but is swollen this is his 2nd round . I noticed today he is slobbering what should I do ? I’m very worried

    • My pit mix has been on 200mg twice a day for about 2 weeks to prepare for Heartworm treatment. He isn’t eating or drinking much, is very lethargic and now has small bumps/sores on his body. He started slobbering, too. Have you gotten any answers, Christy?

      • I’m not sure about the other side effects/symptoms but our vet warned us that our dog may start slobbering a lot during the treatment.

  6. Always call your vet when your dog has a reaction to medication. STOP giving it, until you get the ok or need to bring the dog back in. There are other antibiotics that can help that your dog may not react to. It is bad advice to say keep giving medication if your dog gets sick from it.

  7. After two days at the vet, xrays, ultrasound, multiple blood work in house and sent to the lab the vet was only able to tell me that my baby had an enlarged spleen. They sent me home with Mirtazapine to stimulate his appetite because he stopped eating and Doxycycline. They couldn’t tell me much of anything when they sent me home. Lab work came back and he had some blood in his abdominal cavity and he was mildly anemic. They suggested trying to get his blood count imoroved and then have a splenectomy. After the first dose of Doxycycline he had major difficulty breathing, seemed very disoriented and passed away 12 hours later on the way back to the vet. If I had it to do all over, I wouldnt have let him struggle with the medication. I would’ve eased the pain and let him go peacefully. In his last hours he was suffering and I watched, hoping the medication would wear off and then ask the vet for something else.

    • I am so sorry for your loss. I know first hand how devastating it is to standby helplessly and Watch your pet suffer. From Your description it sounds like your baby died from a ruptured spleen caused by a tumor in the spleen (very common in dogs.) His symptoms likely were unrelated to the medication. I agree that it is better to relieve suffering and let them pass as peacefully as possible instead of prolonging life and causing more suffering.
      I lost my best buddy in April. He also had an enlarged spleen and had a splenectomy. His tumor was cancerous and he passed about 6 weeks after the surgery. He was in pain and suffered the entire 6 weeks. It was heart renching to watch him go through this. If I could do over again, I too would let him pass peacefully rather than extending his suffering with expensive medical procedures that only briefly extended his life and significantly increased his suffering. I wish the veterinarian would have been more honest about the prognosis.

      • Blessings of healing…to all of you who have lost one of your most precious gifts. Please don’t be too hard on yourselves. I’m at that point now myself. Should have, could have , would have. I remember a hospice vet. saying once we often let them linger longer than we realize until after they are gone. Hope wants to persevere. The bond is so incredibly strong we would do almost anything we possibly could, because of they way they have loved us and stuck by us. In your memory my precious Sweet Lady Girl…..

    • My 12-yr-old German Shepherd was prescribed 150mg doxycycline for an infection on his nose. The 1st dose he seemed not himself, after his 2nd evening dose, he started to vomit and continued to vomit for 12 hours. I called my vet first thing in the morning, but my sweet GSD died in my arms before I could get him to the vet. This crap is poison and should be removed from the market. If I had enough $$$ to hire a lawyer, I would sue the life out of the manufacturer and all the veterinarians that prescribe this death pill

  8. My 10 year old pug was put on doxycycline for a sinus infection. After two days she lost interest in eating, began vomiting and appeared confused. She is sleeping a lot. We called the vet and they said stop medication at once. Does anyone have knowledge of how long it takes for the medication to work through their system. Is there an alternate solution?

    • My vet said it should be out of their system in 24 hours, but 4 days later my dog is still suffering the side effects. Won’t eat, labored breathing, disoriented, vomiting, lethargic. This drug should be banned from use completely!

  9. I’m so sorry your loved pet is not feeling better. On the third day of being off doxycycline my pug seems to have made a complete turn around and is doing very well. I agree the drug should be banned from use. Thank you for your response.
    Take care.

  10. I have a 3 yr old German Shepherd with heartworms. She tolerated the first 30 day treatment of the doxycycline and on Friday i had her antigen test run and it was still positive. So another round is called for. I never realized that there was such a reaction to this stuff. But heartworms are serious and I really must treat her. I am also giving her the Ivermectin every 2 weeks. Is anyone else following this protocol for heartworm treatment? Thanks in advance. It is as bad as when my kids were sick!!!!

    • I have a half lab/ half plott hound. He is 1.5 yrs old. Just started on this today. Have to give him 2.5 pills every 12hrs for 28 days.

    • Doxycycline alone will not kill heartworms, it sterilizes the female worms so they cannot reproduce. Your dog also needs to be on a monthly preventative or the immiticide treatment, to kill the heartworms.

    • The Ivermectin (Ivomec) will cost about $40 at Tractor Supply Co. The propylene glycol will cost about $22 for a gallon container. Ivomec will last for up to 3 years in the refrigerator. You will also refrigerate the mixed solution so it will also not go to waste. (only mix 1 cc Ivomec /9 cc propylene glycol solution at a time) shake well before using.
      Once a week with Doxcycline pill for adult worms. Squirt the proper dosage of solution over the dogs food in the bowl, into a special treat for your dog, or in the corner of the dogs mouth. The needle is not on the syringe for this part.
      Repeat the dosage once per month without doxcycline for de-worming your dog over 6 months of age.

  11. My 11 Yr. Old mini-schnauzer mix is diabetic and has to take Humulin N shots(14 units) twice a day. The vet put him on Doxycycline last Wednesday. This weekend we started having eating issues and the diabetes symptoms started again – drinking tons of water and peeing a lot. Have a call into the vet – increase the insulin amount or cease the drug??? Hopefully, this will be resolved immediately.

  12. I have a greyhound with partial paralysis of the larynx. He is 10 years and 7 months old. He developed symptoms two years ago. Not able to handle the cortisone prescribed (had a terrible reaction), he developed pneumonia. My vet prescribed doxycycline. He has been on and off doxycycline since. I don’t know if it is the anti inflammatory effect or bacterial control that maintains his improvement, but at the moment it works.
    Blue is a good eater, and has never had any problems with this drug. He has a loading dose twice daily for ten days ONLY, and copes well. Sometimes his treatment can be only nine weeks apart, depending on when he may react to water or slight food inhalation. Maybe it is more to do with circumstances than the drug??

  13. We have a Golden Retriever and she is almost 11 years old. She developed a cough, hacking type, and took her to an emergency vet as ours was closed. They gave us Furosemide 50 mg, 1 tablet twice a day, and DOXYCYCLINE 100 mg, 3 tablets twice a day. On day 5, monday, she refused to eat anything. She drinks a lot of water though, so i have a call into the vet as we took her off Doxycycline completely due to what we have read about this medication. She weights 72 pounds and according to all we have read, 600 mg is a heck of a lot to take, even 5 mg per pound which is max. Her cough has subsided drastically but she will NOT eat anything. Today is her 2nd day of not eating so i am force feeding her chicken broth to keep her strength up until we hear from the vet. the drug seems to work, but the side effects are terrible.

  14. Once they vomit do you continue giving them the drug? My 7 month old Pomsky just threw up not even five mins after taking it.I tried it with food but he won’t eat so I ended having to making him take it without food. Ugh he is supposed to have kennel cough. I just want my baby to feel better but I’m not going to allow him to continously vomit.

  15. I had trouble with my dog taking this medicine. So I tried this and it helped. I slide the pill into a hot dog and slightly coated it with peanut butter. He gobbles it down. Then right after, I make sure he drinks water than give him brown rice and hamburger. Helped me.. Hope this helps somebody else’s dog- like it did mine.

  16. DO NOT TAKE OR GIVE THIS TO YOUR DOGS!!!! A week ago, the Vet put my dog on this medicine and I gave it to my dog for 3 days, she was lethargic and NOT eating, breathing weird, vomiting, and NOT HER SELF, took her back to the Vet where she passed away within 6 hours. How can a VET give this to their patients? The Vet blamed it on Diabetes, she NEVER HAD DIABETES till then. I am SO MAD!!!!! I want to SUE this company for the cost of my dog (Lhasa Apso) This doctor has LOST a few patients because of this!

  17. My Vet told me to give my dog half a pill of Prilosec that will calm the stomach .Due to my dog started to through up. And do not give them any dairy. I’m surprised that you don’t get informed about the side effects when they give you the antibiotics.

  18. My Brussels Griffon (7 lbs) started this for a bacterial infection because he had a cough and was wheezing. I’ve given it to him for 3 weeks now (yes, 3 and still have at least 3 to go), 1/2 pill every 24 hours, I give it to him with food and have had no problems, except now he’s getting constipated, not sure if i’s the drug or something else. Canned pumpkin is helping with that, but no vomiting, no lethargy, nothing out of the ordinary. After he was on it a few days, he actually perked up from feeling better and his cough went away. Just my personal experience.

  19. I have a almost nine year old yellow lab and almost three weeks ago we took her to the vets for a skin infection, they put her on antibiotics, then she started breathing funny and was laying around and her stomach wasn’t completely healed, so we took her back they put her on amoxicillin and she got worse so we stopped that, took her back for a third time and by this time she’s not eating, breathing funny not doing anything but laying around and they put her on the doxycycline and it’s been two days with everything still the same they suspect leptospirosis, idk if I should stop these meds but if she has the leptospirosis and I don’t give her these meds then she’ll die, I’m so heartbroken to see my family member suffering

  20. My 8yr old Pitt mix started throwing up daily about 3 months ago took her to vet blood test showed two different tick infections( not lyme)gave doxycycline for 30 days took her back but her platelets were still at 4, doxycycline for another 30 days platelets only up to 12, now on vitamin k and doxycycline but she seems to be getting
    worse not better, help.

  21. My 2 year old GS has respiratory infection the vet put her on doxycycline 2 a day. She has been throwing up 2 and 3 times a day, laying around, cant breathe, panting and lathargic and has lost some weight her appetite is still good, not great though. The weird thing is when she throws up it’s not her food it’s a white foamy and watery throw up. I just want my baby back I feel so sorry for her.

  22. My 11 year old Standard Poodle has been on Doxycycline for 12 days. He has experienced vomiting in the past with other antibiotics and was quickly given something else. This time he can not take something else he has been diagnosed with a ” tick virus “. Sadly , my boy was dignosed a year ago from a new vet after my vet for 9 years had retired. That vet misdiagnosed him and did not do proper bloodwork . He was given doxy for two weeks but not the dose. Now fast forward to a new vet do to other issues she did not properly address that I will not get into.. First, did you call the vet and inform them of the issue ? The dog may need a ” Pepcid ” type. I have had to give my boy Pepcid in the past for the same issue. I may even start him on it just in case. My Standard is currently taking chewable Doxycycline and it seems to be better then the capsules he had taken in the past.. if you can not get any help get a second opinion. If I had gotten one last year my boy would not have suffered for a full year with joint pain. The old vet informed me it was typical age issues. My new vet does not believe it’s so and I have seen improvement in his walk. He is 11 so yes he is tired and it’s hot so he hates hot weather. I have been using a ” raw topper ” on his meals prior to giving him his food . Mostly, my guy is a grazer so he has access to his food whenever. I hope you can get some relief for your baby. I give my guy his medications and do not let him do anything for 1-2 hours but chill. Then for the next 3-4 I keep an eye on him..try to find out if he needs something else maybe not from medication maybe a secondary thing going on.. my guy in the past was on Doxycycline twice and then needed a shot for a cough or irritation ( maybe a steroid ) Feel better Baby.,

  23. The usual side effects are nausea, vomiting, and diarrhea. And antibiotics period make people and animals feel yucky. My 20 yr old chihuahua, Penny, was on doxy for a respiratory infection. She amazingly didn’t vomit, but had a bit of diarrhea, and laid around lethargic a few days. However, it cleared up her infection and she’s doing a lot better. It was rough watching her go through everything, but definitely worth it. Of course nothing she went through on doxy was life threatening. She kept a healthy appetite, drank plenty of water, thank goodness.

  24. My 2 year old pit bull had ACL surgery in the middle of July, 2weeks later she developed a UTI which ultimately lead to another surgery to remove both lymph noids by her groin. While waiting for the biopsy results she was put on doxycycline, 10 days into doxycycline she has lower extremitie and entire left side of her body paralysis. The neurology specialist recommended taking her off doxycycline and see if there are any improvements in 48 hours. He advised this can cause paralysis in dogs!! I have been researching this and have NOT found paralysis listed on side effects anywhere!!

  25. My dog, an 80 lbs Akita/lab? mix has been on 400 mg per day Doxycycline. The first day he drank about 1 quart of water, yesterday he drank about 1 pint of water, and I’m trying to get the last ounce or so of water from a 16.9 ounce bottle of water in him now.

    It seems to upset his stomach a little when he drinks water on top of it, I can hear his stomach growl when he drinks a little water. I think maybe giving him more water an hour or two before it’s time for his pills will yield better results. I’m going to call the vet to be sure.

    He has improved over the past 3 days, he’s sleeping all night and wags his tail more, but the slow down in water consumption has me worried.

    • My lab mix started taking Doxycycline last Tuesday (1/30/18) for heartworms and congestive heart failure, by that Saturday morning she had not eaten anything and was very very lethargic. We took her to her “grandma’s” (my in laws” house and she ate a whole plate of food and was so happy and energetic. Fast toward to this past Wednesday (2/7/18) and she has again gone back to not eating and now will not walk anywhere. We have to carry her throughout the house and outside to potty on top of vomiting. Vet said to take her off of the doxycycline for a few days and see if she gets better, but if she does then we still run into the risk of her going right back to how she is now once we start her back on it. But if she doesn’t get better within a few days then we have no choice but to put her down 🙁

  26. I have been dealing with a lyme count of 134 in my 11yr mixed breed. The problem/treatment is a double edge sword . The illness and treatment both cause lethargy, loss of appetite as well as many other issues. My dog initially was taking the Doxy hidden in food treats but after 2 or3 days of starting refusing them and when from eating very little to refusal of all food items and i tried EVERYTHING. So iwas forced to “pill him” where i would force him to take the pills by coaxing his mouth open and putting them as deep as i could in his throat and then cupping my hand s surrounding his mouth until he swallowed them. By the second day of this both he and i were very traumatized and he became very anxious and nervous and would even curl his lip when i would attempt. This was heart wrenching given the relationship i have with this kind hearted soul. the vet ultimately recommended that i bring him to a 24/7 clinic that would hook him up to an IV. after speaking to a few of these clinic they said for anything to be effective my dog would need to be with them for at least 3 days at a cost of 3to4 thousand dollars. Unfortunately that amount isnt in the reality of what i can afford. I asked if there was anything else and he said the Pharmacy could formulate the meds into a flavored liquid that he might be willing to eat or a trans-dermal. Given i couldnt get him to eat much of anything at this point i opted for the transdermal as i knew he would eat any flavored meds no matter how well it tasted. My Guinness has now been on the transdermal for about 3 days. i just use a convenient dispenser and a measured dab is then taken by your finger with finger cap and you rub it into the dogs ear. He has no problem with this and as of yesterday has eaten a little more . today he ate more too. im convinced he had associated the food with the meds as upsetting his stomach . and given the lymes causing loss of appetite that is a terrible combo. Today he ate some of his original kibble that up to this point he has refused to touch. Granted it wasnt a significant amount but it was encouraging. there are concerns as to the effectiveness of the transderrmal but the vet used a high dose to compensate for this and in my case feel it has been very helpful. I highly recommend those of you that are having the food refusal issues as an issue give this a try. im not out of the woods and it hasnt been a panacea but i am hopeful for the first time in about 2 weeks.

  27. My poor little girl (9 year old, 8 pound pound chihuahua) is suffering from Lyme Disease. Her little paw joints on the front paws are so swollen she can’t walk, her paws are useless. Symptons appeared June 2017.. I took her to the vet, they gave her predisone and doxcyline…a 30 day supply, they said it may or may not work..she did better for a little while, and then slowly progressed back to not being able to walk or get up by herself. I had almost made the decision to let her go so her suffering would end, but then looking into her beautiful little eyes, I decided to try the doxcline again..50 mg twice daily. I hope and pray this works again for her..she gets so embarrassed peeing on herself while I am at work. I’m sorry if you’ve had a bad experience with this medicine. Please get your dog vacinated with the lyme vaccine..she got bit one time 5 years ago, the virus had laid dorminant for 4 years… Its horrible to watch..she used to run and play, now all she can do is lay, she’s still alert thro, still lets mommy know when something isn’t right around the house…she eats and drinks…she just can’t use her front legs, and her back legs have become shaky and wobbly..her front paws look like she has severe rrheumatoid arthritis, curled up and deformed. It makes me so sad. Good luck to all..Love your babies and enjoy every second you have with them:)

  28. I have a rescue pup that came from the Dominican. All his pics look as if he was fine. When he arrived he had a cough (due from the tube down his throats from being neutered) and a really bad eye infection and his ears were packed with dirt gunk. He came with these pills. I’m the three weeks we have had him everyday he gets worse and we were getting to the point that we thought we would have to put him down. The first vet tried to tell us he had distemper and the second just seemed really worried as r we. We have takin him off these pill and r praying this is the answer. We fell hard fast for our lil fur baby.
    His symptoms are bad balance (could be ear though) but now his legs seem like jelly, sweating all the time, a rash all over his body and some kind of leakage with a horrible odour.

  29. MY 20 lb rat terrier MACY was prescribed this for a sinus infection. I had noticed she wasn’t feeling well and called my vet to find out if it was safe to continue her on it. THey told me it was an antibiotic and it’s what she was taking to get better…She had one more dose that evening and then threw up and was miserable the next two days. she had refused to eat and threw up everything. on the 3rd morning she suffered liver failure and I rushed her to the vet where they told me she was poisoned and I had to put her down!!! THESE PILLS KILLED MY DOG!!!! DO NOT GIVE THIS HORRIBLE DRUG TO YOUR DOG!!! I will never ever trust a vetenerian again:(( nothing will bring her back and I am so sad this happened and so MAD….

    • Gina Sherry, God Bless and you will be in my Thoughts and Prayers…. I am with you on trusting Vets Doctors… For the Past 2 months, have been to 3 doctors with my almost 11 year Young Bichion… First, I notice Rascal was not seeing well and took to my Normal Vets… and he keep telling me Rascal was fine and could see just fine… said could be a little bit of Cataracts… and I keep taking him back and after the 3rd trip Rascal could Not see at all…. So, he sent me to a Specialist for Eyes, come to find out Rascal had Ritinal Detachment:( First I have ever heard, and I am a OR Nurse, and yes, I have scrub on many Cataracts cases, but not ever going to this Specialist was I ready to hear this…. no bed side Manners at all saying well you have 2 options, Go to New York and get Surgery since the are Only 5 doctors in the USA that does this Surgery, OR he could stay blind… WTHeck……… Now remember I was sent to a Specialist, and he was 2.5 hours away from where I lived and telling me to go to New York to have surgery and would have to get a Hotel as Rascal would have to be seen by doctor the next day after surgery…. Well came home and Reserched and found one closer in Virginia Beach witch is almost 4 hours from me and same have to stay in Dog Friendly Hotel so Rascal could be Checked next Day,,,, Well Yesterday, Was my 3rd Trip trying to have this Surgery for Rascal and each time the doctor stay OH TO MUCH BLOOD OR THIS OR THAT….. Ever time still a charge to be seen of almost 400.00 dollars… and STILL NO SURGERY AND RASCAL IS STILL BLIND…. Well yesterday, Thank GOD I AM A NURSE IN THE OR…. I SAW THE ULTRA SOUND AND I WAS HEY THAT IS THICK AND STILL ATTACHED… And he said to me you are right, the LEFT EYE is still attached …. just the blood in the back of his eye he said is why he is not seeing out of this EYE….. and he put him on this medicine you are saying killed your Fur Baby, well after 3 doses, Rascal got sick, was falling out and looked bad, keep trying to call vet and no answer and voice boxes all full and I went as far to leave on his face book this…. REALLY…. So, I have took him off and I did a IV myself on him and he seems to be better Thank God…. Before, my dog went for the FIRST time to have Surgery, my home Vet did full work up on Heart, Liver, and Blood Work and all fine, since all this Rascal has been put on 3 medicines, 2 eye drops and like I have said I have gone 3 times now to have his Surgery done and getting Hotel and you do NOT get a Refund and have to Book since it is a DOG Friendly Hotel…. I am not Rich or Poor, But, so far these VETS… have received almost 5,ooo dollars and NO SURGERY YET, AND MY DOG IS BLIND:( 🙁 🙁 and as of tonight still no phone call about the medicine that left me and Rascal MISERABLE…. And they did not do any blood work yesterday and just put him on this…??? it’s a MONEY MAKING GIG AND WE ALL LOVE OUR FUR CHILDREN…. Being a Nurse myself for almost 20 years, I would NEVER treat a Human or Animal the way we have been Treated for the last few Months…. God Bless all and no animal should Ever be put on this Horrible medicine…. God Bless….

  30. Help! I just read the last post and I am horrified. I have a rescue that came from Thailand. She seemed a little off when I got her but nothing insurmountable. Mostly Arthritic hind legs and hips ans some missing ans rottinh teeth. We guessed She may be older than the 6/7 years we were told.
    She was having some digestive problems. Diarrea and blood in her stool. When tests were run everything looked normal except for a positive result for exposure to Ehrlichiosis. We put her in a bland diet and probiotics she got better than relapsed while I was out of town. Her co- Foster took her in and they gave her Metronidazole. I am told that the next night she woke up screaming in pain. Michelle, the co-foster called the vet clinic and our original doctor was out of the office so the vet on staff checked her chart and upon seeing the Ehrlichiosis, prescribed 28 days of 100 mg doxycycline. Well, when I got back a week later the poor thing seemed deathly ill. I took her off the Metronidazole right away but continued on he Doxy at my vets urging. In the mean time we tested her for active infection. It took another week to get the results for that and in the mean time the poor girl has progressively gotten worse. She is showing clear signs of neurological issues, dimentia, head tilt, Pain in her joints, and in the last few days blindness. She seems weaker and more depleted every day. Some days She has episodes of anxiety, walking in circles for hours, and then collapsing. I know that their is a die off period w/ tick born Illness because I myself went through the Doxycycline regimen for Lyme last year. I know it gets worse before it gets better but I feel like we are killing her. Btw, test results came back negative but vet thinks it’s because she tested after Antibiotics were started. Everyone insists I have to complete the whole round but I want to stop. Something seems really wrong. She’s on day 17. Vet says I can stop her at 21 but I’m seriously afraid she won’t make it. And I doubt she can regain her eyesight. Has anyone heard of this happening. I’m at my wits end. I can’t bear to watch and possibly aid in this poor, sweet critter’s suffering.

  31. Our rescue group uses Doxycycline for Ehlichea. Ehlichea is at epidemic levels here in Mexico (75% of the dogs we treat have Ehrlichea), due to high tick populations. Although a few dogs had stomach problems, using a stomach coating medication, like Omeprazol helps. Two of the dogs have had to take Doxycycline via injection. It has been a life saver for many dogs here.

  32. I had my little 6.6 pound Chihuahua on 25 mg of Doxy for 30 days prior to heartworm treatment. The only symptoms she showed were upset tummy and not wanting to eat very much. It was suggested to give her Pepcid AC before the Doxy but I didn’t see much of a difference. Then towards the end of the 30 day treatment, I noticed her fur began to fall in chunks. The slightest touch to her would make her shed enormous amount of fur. I noticed this was not normal for her. She’s lost and is still loosing huge chunks of fur even after completing the regimen and the vet didn’t know why. I foundout that hair loss is a side effect of Doxy. After reading how this drug causes neurological problems in animals, I will not ever place her back on it. I pray and hope my little one has not suffered any permanent damage because of this antibiotic. If you suspect that your pet is suffering because of this drug, take them off of it and let the vet know. Don’t risk his or her life.

  33. 100 mg once every 12 hours was prescribed to our 11 year Beagle Chloe as the first steps in heartworm treatment. Poor thing stopped eating after the 3rd day of starting on it and she never bounced back. She was lethargic, weak, and barely drank water. The vet said to not give it to her for a few days until she gets her appetite back. Guess what, she never made it that far. She died one week after first staring on it. Please be very cautious of this medication. I wish I did research on the medication as she would probably still be alive.

  34. My 9 year old husky was put on this crap and 1 week later she died.. tonight. Took her to a all night emergency clinic and one look at her and the vet knew the medication she was taking. She started breathing heavy, seizure, foaming at the mouth and could not walk or stand up.. this all happened with in 2 hours.. they killed my dog…

  35. I took my nine-plus-year-old 60-pount Pyrenees Mix to the vet because he seemed lethargic. He was diagnosed with erhlichiosis and prescribed Doxycline. About five hours after receiving his first dose of the medicine, he died. I am devasted. My vet said he must have had some underlying issue…? Up until that day, he showed no signs of being ill. He had not lost weight.
