So what can I give my dog for allergies? Zyrtec is a brand name for cetirizine hydrochloride, a relatively new available over-the-counter antihistamine that’s commonly prescribed by veterinarians to help relieve common allergies that affect canines.
Many veterinarians prefer to use Zyrtec only when Benadryl doesn’t lead to any improvements in the dog’s condition.
Cetirizine is mainly intended for human use and not animal use, despite the fact that many veterinarians prescribe it to pet patients who have certain types of allergies.
Which brings us to the question, is cetirizine, or Zyrtec as we will be referring to it from now on in this article by its brand name, safe for dogs?
Is Zyrtec Safe For Dogs To Take?
In short, YES, Zyrtec is safe to use on canines, on one condition though, and that is that you follow all the rules and proper dosages that apply.
We will get to that in just a bit, though.
What Can I Give My Dog Zyrtec For?
Usually, the most common problems that veterinarians refer to Zyrtec to treats in dogs are skin problems that mostly show on pups between the age of 1-3 years, among which are:
- Dermatitis: Where your dog’s skin becomes very itchy.
If your furry friend has skin allergies that needs something like Zyrtec to solve, you will see some or all of these symptoms in your canine:
- Skin itchiness and irritation that leads them to scratch
- Excessive face rubbing
- Hair loss
- Swelling in various skin areas
- Excessive head shaking
- Excessive chewing of body parts like paws or legs
- Excessive licking
If you see any of these symptoms in your pup, you have to immediately get them to professional animal care, because if left untreated, your dog could develop potentially life-threatening diseases.
Which Form Of Zyrtec Is Safe For Dogs?
You MUST make sure that the formulation of Zyrtec you give to your dog has only one active ingredient, which is cetirizine.
Other formulations out there, most common of which is “Zyrtec-D”, contains other very deadly ingredients to dogs such as pseudoepehedrine, and should never be given to animals.
So, make sure you carefully read the active ingredients on the product packaging before you give it to your canine as treatment, and make sure you NEVER EVER give “Zyrtec-D” to your dog.
Some studies show very scary numbers regarding “Zyrtec-D”, such as finding that as little as two tablets could be enough to kill a small sized dog.
What Is The Correct Zyrtec Dosage For Dogs?
Before we kick off this section, please note that any of these dosages are scientific estimates at best.
You should always consult your veterinarian before you start a course of treatment for your dog with this medication or any other, as they will tell you the exact cetirizine dosage for dogs and all other details you should know.
Generally, cetirizine is taken orally, in a tablet form, once a day. The required dosage is mostly determined by your companion’s weight.
The standard recommended Zyrtec dosage for dogs is:
- Dogs over 10 lbs: Give one 10mg tablet once daily
- Dogs under 10 lbs: Give one-half of a 10mg tablet once daily
You can feel free to give Zyrtec to your pet alone or with some food, whatever works best for them.
If you suspect that your canine has overdosed on Zyrtec, immediately contact your veterinarian so they tell you the necessary steps you have to do.
When Is Zyrtec Harmful To Dogs?
Here’s a list of some of the circumstances where you should be extra careful about giving your dog Zyrtec:
– Liver Or Kidney Problems: Giving your dog Zyrtec if they’re known to have liver or kidney problems can be very dangerous, mainly because it can cause urine retention and worsen either situation, so you have to consult with your veterinarian first to determine the severity of the issue
– Hypersensitivity: Some dogs are known to be hypersensitive to antihistamines, in which case they should not be administered any Zyrtec.
– Pregnancy: There are not sufficient studies that show that Zyrtec is safe to be given to dogs which are pregnant, so be extra careful on this one
– Nursing: Nursing dogs can pass some Zyrtec in the milk they give to their puppies, so they shouldn’t be given any during this period
