What human antihistamine is safe for my dog with allergies and liver issues?

Updated On September 23rd, 2025

Pet's info: Dog | Pug | Female | unspayed | 1 year and 9 months old | 18 lbs

Hi I believe my pug has bad allergies (runny nose blocked at night, eye discharge, redness, sneezing). I've eliminated dust, dust mites and droppings so pollen seems to be the best fit. We live in Nepal and the pictures show the plants outside our house! I think there's ragweed there, not sure. She has liver problems too. She's allergic to wheat, diary and chicken. Histamine affects the liver right? What's a good antihistamine for her? We can only get human medicine here. Thank u!

Hydroxyzine and Diphenhydramine are both human anti-histamines commonly utilized in the vet field for allergies. Histamines do not directly affect the liver, but will certainly have indirect effects.
