Atopic dermatitis (AD) or environmental allergy is a complicated disease which may often include a combination of genetic factors, environmental factors, skin immune dysfunction, diet and skin barrier dysfunction. AD is an over-reaction to typically innocuous environmental allergens such as pollens, molds, etc. Dogs absorb allergens across their skin. In dogs with concurrent skin barrier deficiencies, allergens penetrate deeper into the skin and are taken up by specialized immune cells. Allergy manifests itself in different ways, the most common being pruritus (itching). Signs of pruritus are scratching, licking, chewing, biting, and rubbing.
