My dog gained weight. Should I change his Zyrtec allergy dose?

Your vet is correct in this dosage. Zyrtec dosage for a pet this size is a little over 30 mgs daily. : ) Pet dosage and human dosages are different based on our metabolism differences. Also your pets weight converted into kg's is 32.7 kg's. Thanks for visiting Petco Pet Education Center, formerly Petcoach. Take care : )

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.

Dogs around 10 pounds in weight should only get a half tab once per day. If the Zyrtec doesn't seem to be working, or seems to wear off too quickly, I would contact Hope's vet. It may be time to switch to a stronger medication, or try a different OTC such as Claritin to see if it is better for longer-term control of Hope's allergies.

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/

Hello and welcome to Petco Pet Education Center, formerly Petcoach. Ear mites won't be treated with zyrtec (which is an anti-histamine). They need a parasite treatment for this (ex. Revolution, Advantage Multi, etc.). Allergies also don't lead to ear mites. It could be that Corbin has a build-up of wax and itchy ears from allergies, which can be treated with Zyrtec. The typically dose is 1mg/kg so an 11lb dog would get about 5mg. Please ensure that Cetirizine is the ONLY active ingredient. Best of luck with Corbin!

Yes, you can give cetirizine as needed. Be aware that if you use it constantly there is a chance he will become tolerant to it and will no longer work. It should also not be used in animals that have any underlying kidney or liver disease. Please review this article on the medication in regards to dosing, side effects, etc. ( https://www.petcoach.co/pet-medication/cetirizine/ )

Both drugs are used off-label - meaning that they are not approved for veterinary use, so it's important to only use them as recommended by your veterinarian. Xyzal has a similar drug to Zyrtec, but is different enough that a new dose would have to be calculated by your veterinarian. This drug also has a lack of safety information for use with dogs, so I would not recommend it. I hope that helps and all is well with Mo.
