Atopy - Inhallant Allergy

On physical exam the most common signs are scratching and licking of the skin and ear flapping. Most common areas of the skin affected are the face, feet and the arm pits. It’s often seasonal as the allergens that are causing the problem will only be available at certain times of the year. Because of skin irritation, secondary infections are not uncommon.

Atopy needs to be distinguished from food sensitivities, fleabite dermatitis, skin infections, mites and contact dermatitis. Special testing may be required to distinguish between these diseases. Your veterinarian will make recommendations regarding which tests are best suited to diagnose this problem.

After diagnosis, a variety of treatments are available. It is important to understand that allergies are a lifelong problem. While we can control the symptoms we can’t always cure the problem. If a food allergy is suspected, dietary change may be all that is necessary. If inhalant allergies are also at work, medications and possibly hypersensitivity injection treatment (hypersensitization) may be required. Medications can range from antihistamines to glucocorticoids (commonly called steroids). Hypersensitization means giving injections to reduce your pet’s response to the allergen. Your veterinarian will explain how this is done. Reducing exposure to the offending allergen is also recommended. This is often not feasible.

If your pet has been diagnosed with Atopy, you can expect to have treatment needed at least once a year. Many times, the patient needs to return to the hospital for routine checkups at least twice a year. Secondary skin infections are common in Atopy patients and need to be addressed as soon as possible. If there is a secondary bacterial skin infection, antibiotics may also be used. Although not life threatening, Atopy can make your pet very uncomfortable, and for that reason we do recommend treatment when the condition is diagnosed.

If your dog has a "seasonal allergy", be aware that the majority of atopic dogs experience itching during the seasons when flowers, grasses or trees are blooming and producing pollen. Seasonal allergy and atopy both describe allergic skin disease. Some atopic dogs have problems year-round because their allergen or allergens are always present. The house dust mite is usually the cause of non-seasonal atopy, but some dogs develop separate allergies that cause them to constantly itch.

Allergies to grass should be termed "grass pollen allergies". Pollens are airborne. Keeping the grass closely cut to prevent seeding will help, but there is little else that you can do to keep your pet from being exposed to airborne grass pollen from the rest of the neighborhood - or town.It will not hurt for your dog to walk on grass.

Dogs with chronic skin infections or allergies should also be tested for hypothyroidism because hypothyroidism affects the skin and may exacerbate allergic skin conditions. Allergies can cause the skin to produce more sebum (seborrhea), an oily material that will cause a musty odor. Other causes of skin odor can be a skin or ear infection or yeast and bacterial infections. After the itching and scratching are under control, the odor and seborrhea should clear up. Anti-inflammatory medications and desensitization therapy will often fail to help a pet with hypothyroidism.

Some dogs can benefit from frequent bathing with special shampoos. Research has shown that some allergens are absorbed through the skin. Your veterinarian may prescribe an appropriate hypoallergenic shampoo.
