Hi,
My 7 months Basenji just got neutered and the rash and hives started after his surgery, he was fine before that. He started getting rash on his belly and broke out in hives. We took him the vet and got him treated, yet the rash and small little hives are still there. We were instructed to give him Benadryl every 8 hrs. Currently he's on Dick Van Patten's Natural Balance Dog Food, which contain no artificial preservatives, flavors, or colors. I dont know what else to do because he's having trouble sleeping at night.
How soon after being neutered? Is the surgery site healed? And I would have to think of a yeast infection… and since the benadryl has not cleared it up, I would insist on the Vet taking a further look. Also, is he on any meds from the surgery?
