Stella was on pro-plan puppy food from the breeder and since we got her last sunday I have switched her over to Fromm Salmon a La Veg. On thursday she started with a rash on her belly, it is red bumpy but flat then it started on her chest and in her ears. She doesnt bother with it at all. I have given her a couple doses of benadryl but doesnt seem to make any difference. I did give her a bath on thursday with Johnson baby soap(thats what the breeder was using) Silva is on Fromm surf and turf. I am wondering if it is an allergy to the food or something outside?? I am going to the pet food store today but they dont carry Fromm, they order it for me so I was looking at the food recommendations on here and maybe might have to try a different brand of food?? Any suggestions, should I take her to the vet?? If I change foods how long till I see an improvement?? Thanks!!
