What are the symptoms of allergic and irritant contact dermatitis? - dermatitis. more condition_symptoms

I want to check with other pet owners to make sure my vet diagnosis is correct, because I never heard of allergic contact dermatitis or irritation heard in the dog. My dog has buttons around the legs are red. I continue to lick, because if you do, they bleed. It sounds like allergic contact dermatitis or irritant to you?
