Evaluate what your dog was doing before he started swelling. Hives usually appear within 30 minutes after something triggers them. Try and expose what may have caused this allergic reaction in your dog. It could be an environmental issue like mold, preservatives in foods, insect bites or even from stress.
If the hives do not disappear with the help of a cool bath or topical solution, see your vet. Your pet may need to have a blood test or be given an oral medication.
A dog can also get a skin rash due to an allergic reaction. This may be from pollen in the air or certain cleaning agents and toxins in your home. There are also some medications that cause hives and skin infections in dogs.
