Atopy in Dogs

Atopy is a hereditary skin disease of dogs, characterised by skin inflammation and itchiness (pruritus). Current understanding is that it is caused by an abnormal reaction of the immune system to tiny particles in the environment called allergens, combined with abnormalities in the surface layer (stratum corneum) of the skin. Allergens enter the body through the skin and lead to the production of certain antibodies in genetically predisposed animals. These antibodies then cause either intermittent or chronic (long-term) symptoms.
