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

Updated On September 23rd, 2025

Pet's info: Dog | Cavalier King Charles Spaniel | Female | spayed | 4 years and 11 months old | 17 lbs

How much Zyrtec can I give my 17 pound dog per day? My vet recommended me a dosage but I stopped using it for a bit because her allergy symptoms went away. (Mild Itching/scratching) and I forgot what he told me. She was previously on 25 mg. Of Benadryl before he suggested Zyrtec would work better. The bottle I have now says it's 10 mg. Per tablet. Should i give one or two? thanks!

Legally, we are prohibited from providing dosing information, even for OTC medications, in the absence of a physical exam and a patient-veterinarian-client relationship. Contact your veterinarian who can give you a dose based on Chloe's current weight.

    It is illegal for us to give advice about over-the-counter human medications without a valid client patient relationship. I recommend to call your veterinarian who will be able to give you this information. Please feel free to post any additional questions.
