dogs can suffer from allergies

As in the human population, the incidence of allergies in pets seems to be increasing. While allergic humans may often sneeze, wheeze or even have serious respiratory difficulties, allergic reactions in pets are mostly characterized by skin problems, exacerbated by their primary symptom—itching and scratching. Dog allergies fall into three main categories: flea allergic dermatitis, atopy, and food allergy. Many pets can be affected by one or more allergy.
