Pet's info: Dog | Border Terrier | Female | spayed | 35 lbs

I came home from work and noticed these red bumps all over my dog. I gave her some Benadryl because it seems to be an alerigic reaction. But it's gotten worst over the last 24 hours. I need advise please.

Poor Bailey! If you already gave oral Benadryl and it is not better then she needs to be seen by a vet for treatment. Your vet an give an injection of a corticosteroid and Benadryl which should help resolve the hives.

    Poor Girl! This could be an allergic reaction or an infection, but without seeing it, I cannot say for sure. I would start by trying some benadryl twice a day. See link below. If she isn't improving, I would have your vet take a look at her as she likely will need some stronger allergy meds and some oral antibiotics. I hope this helps! https://www.petcoach.co/canigive/dog/benadryl/#
