My dog has worsening itching, hives, and rashes. Food or environment?

Updated On September 23rd, 2025

Pet's info: Dog | Pit Bull Terrier | Male | neutered | 3 years and 3 months old | 45 lbs

I got my dog about 5 weeks ago, 45 lb pitbull. He had very very mild itching when I got him. Then one day he had hives on his back about 3 weeks ago that come and go daily. The last 1-2 weeks he’s gotten worse everyday with itching/cuts/red rashes everywhere, mainly his back/neck/behind, but definitely all over. He’s on diamond naturals salmon & potato grain free. flea protected, had baths with hypoallergenic and treatment shampoos, nothing is working! Should I switch food? Or is it environment

It could be the environment. Have Kane seen by a vet. The vet can diagnose what is causing his hives, and can treat it. I would switch his food, however, as grain free food is not good for dogs. Vets are seeing an increase in dilated cardiomyopathy in dogs fed grain free food, and the FDA is investigating that link. Grain allergies are actually very rare. I'd put Kane on a food with grains from a brand such a Hill's Science Diet, Purina ProPlan, Royal Canin, or Iams. I hope this helps!
