Dogs with Atopic Dermatitis: Causes, Diagnosis, and Treatment

continued...

Most dogs with atopy respond well to treatment. A first and most important step is to reduce the threshold for scratching by treating and eliminating all associated irritative skin problems, such as fleas, seborrhea, and pyoderma. Wipe the dog down with a damp towel when she comes in from outdoors, which helps remove pollens picked up in the coat.

Antihistamines control itching and scratching in 20 to 40 percent of atopic dogs. Corticosteroids are the most effective anti-itch drugs, but also have the most serious side effects. They are best used intermittently in low doses and for a limited time. Preparations containing hydrocortisone withPramoxine are often prescribed for treating local areas of itching. Pramoxine is a topical anesthetic that provides temporary relief from pain and itching.

Derm Caps and other essential omega-3 fatty acid products derived from fish oils have produced good results in some dogs. They are used as nutritional supplements in conjunction with other therapies. A variety of shampoos is available and may be prescribed by your veterinarian to rehydrate the skin, treat bacterial infection, and control seborrhea.

Dogs who do not respond to medical treatment can be considered for immunotherapy with hyposensitization. This involves skin testing to identify the allergen(s) and then desensitizing the dog to the specific irritants through a series of injections given over a period of 9 to 12 months or longer. Some dogs will require periodic boosters during times when allergens are heavy.

Some dogs with atopy benefit from switching to a higher-quality dog food, even if they don’t have a food allergy. And if they are allergic to house dust mites, they often cross-react with grain mites and will benefit from a canned food or kibble that has no grain.
