What is dog dermatitis?

Dermatitis is a very broad, general term, and it just means inflammation of the skin. It can be caused by innumerable different things. It's just a general term. Really, it doesn't mean anything. If your dog has dermatitis, it just tells me it has a skin problem and very little after that.

Dermatitis is the inflammation or irritation of the skin. It's as simple as that. We have a term called dermatology, which is the study of skin conditions.
