How much Zyrtec can I give my dog for allergy itching relief?

Legally, we are prohibited from providing doses, even for OTC medications, in the absence of a physical exam and VPCR ( Veterinarian-Patient-Client Relationship). A true and valid VPCR cannot be established in an online forum. Additionally, the itching and scratching may not be due to allergies, in which case the cetirizine will be ineffective. Ideally, Suki should be seen by your veterinarian to diagnose the underlying cause. In the meantime, place an e-collar (cone) on her to prevent licking or chewing. Confirm she is on a flea preventive and check her over for any stray fleas. Discuss allergy testing, food elimination trials and hydrolyzed diets with the vet.

Yes, there is an OTC in the form of antihistamines, but legally I cannot recommend it for you to use on her, nor can I give you the dose. That's because doing so requires a veterinary client patient relationship which cannot be achieved via an internet forum. In addition, I cannot say for certain if a specific drug is safe for your dog. I would give your vet a call to get the name of the OTC option as well as the dosage.

The published dose for Zyrtec in dogs is 1 mg/kg which would be 7.7 mg for Mollie. Since the tablet only comes in 10 mg, your vet probably wanted to round so that Mollie wasn't underdosed. I wouldn't recommend changing the dose without talking to your vet first.

Most OTC antihistamines can be used in dogs, however you should **never** give any medications to your dog without the advice of your veterinarian. Legally though, we cannot direct you to medicate your pet in the absence of a physical exam and a VCPR (veterinarian-client-patient-relationship). [Allergies](https://www.petcoach.co/dog/condition/canine-allergies) can be frustrating to diagnose since they can have multiple causes ([environmental](https://www.petcoach.co/article/food-allergies-vs-environmental-allergies-whats-the-difference), [food](https://www.petcoach.co/dog/condition/food-allergies), [flea bites](https://www.petcoach.co/dog/condition/flea-allergy), etc.). Schedule an appointment with your veterinarian. Discuss [food elimination trials](https://www.petcoach.co/article/food-trials-for-allergies-in-pets-what-to-expect) and [allergy testing](https://www.petcoach.co/article/allergy-testing-immunotherapy-in-dogs) and if antihistamine use is indicated, he or she can give you a proper dose, The medication may provide some relief but your task is to try to determine what your dog is allergic to and decrease or eliminate it.

Thanks for using Petco Pet Education Center, formerly Petcoach! Yes this medication can be given to dogs. However, I would recommend you check in with your veterinarian first as they know his medical history. Keep in mind some of these drugs can interact with other drugs or diseases and be harmful to a patient which is why I recommend you check in with your veterinarian first. Best of luck!

Hi and thanks for your request. Once daily (once every 24 hours, so every day at 2am) would be correct. The dosage you are giving is on the higher range, make sure you do not exceed 20mg per day. https://www.petcoach.co/canigive/dog/zyrtec/

No, I wouldn't recommend doing this without speaking to your vet about it. That's because recommending to do this requires a veterinary client patient relationship which cannot be achieved via an internet forum. In addition, I cannot say for certain if a specific drug is safe for Zoey. Give your vet a call, and they can let you know if Levocetirizine 5mg is safe to give her.
