Atopic dermatitis is an inflammatory, chronic skin disease associated with allergies. In fact, this is the second most common allergic skin disease in dogs. These allergic reactions can be brought on by normally harmless substances like grass, mold spores, house dust mites, and other environmental allergens.
Dogs normally show signs of the disease between 3 months and 6 years of age, though atopic dermatitis can be so mild the first year that it does not become clinically apparent before the third year.
Despite the fact dogs are more prone to atopic dermatitis than cats, it does occur in felines. If you would like to learn more about how this disease affects cats, please visit this page in the PetMD health library.
Symptoms and Types
Often symptoms associated with atopic dermatitis progressively worsen with time, though they become more apparent during certain seasons. The most commonly affected areas in dogs include the:
Around the eyes
In between the toes
The signs associated with atopic dermatitis, meanwhile, consist of itching, scratching, rubbing, and licking, especially around the face, paws, and underarms.
Early onset is often associated with a family history of skin allergies. This may lead the dog to become more susceptible to allergens such as:
Airborne pollens (grasses, weeds, trees, etc.)
Mold spores (indoor and outdoor)
House dust mite
Your veterinarian will want a complete medical history to determine the underlying cause of the skin allergies, including a physical examination of the dog.
Serologic allergy testing may be performed, but it does not always have reliable results. The quality of this kind of testing often depends on the laboratory which analyzes the results. Intradermal testing, whereby small amounts of test allergens are injected in the skin and wheal (a red bump) response is measured, may also used to identify the cause of your pet's allergic reaction.
