My 11lb Maltese has itchy ears. Can Zyrtec help, and what's the dose?

My 11 lb Maltese seems to have ear mites. This has happened in the past and was attributed to allergy issues. I remember being told that I could give him Zyrtec, but was unsure of the right dosage. Can you help?

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!
