Dog Skin Allergies

Dogs with skin allergies are often genetically predisposed to the condition. Canine atopy or atopic dermatitis can be defined as a genetic predisposition to developing allergic skin disease caused by environmental allergens such as dust, mold, and pollen. About 80% of dogs with allergies will start with seasonal allergies during the summer months but many dogs will eventually develop clinical signs throughout the year. Some breeds seem to be more affected than others including the Chinese Shar-Pei, West Highland Terrier, Scottish Terrier, English Setter, Labrador, Boxer, and Golden Retriever.

Some dogs that have issues relating to environmental allergens usually develop eye and ear infections. In rare cases some dogs may also develop gastrointestinal diseases such as diarrhea or colitis. It’s also important to remember that many dogs with allergies react to more than one type of allergen. In all cases, a food trial should be done to rule out the possibility of a food allergy. Dogs with allergies are often treated with the same medications used to treat humans. Essential fatty acids can also be used and clinical trials have shown that they benefit about 30% of allergic dogs. Essential fatty acids are often given in combination with other medications such as antihistamines and glucocorticoids. However, it may take 8-12 weeks to see results.
