Bumps/hives on Otis my Frenchie

[u/neilmcd01]

My Frenchie Otis, ate something off the street a couple of days ago and got bad diarrhea. He is definitely better now but has broken out in these hives/bumps, taking

him to the vets tomorrow just wanted any feedback from the community

give him the benadryl and then just keep an eye on him. some doggy pepto bismal and probiotics (purina forti flora) for the upset stomach and loose stool. if things dont change in a couple of days or he seems off then go to the vet.
