The most common reaction to allergens in dogs are skin problems. The primary symptoms are licking, biting, and scratching. Skin problems can be difficult to diagnose because there are so many different causes. Finding the correct diagnosis leads to the best dog allergies treatment for your pet.

Some allergens can be avoided. Others, like dust and pollen, must be managed. Medicated shampoos and topical sprays provide temporary relief for itchy skin. Antihistamines and corticosteroids reduce inflammation. When these aren't enough, allergy shots desensitize the dogs reaction to allergens. A vet will evaluate symptoms, the physical condition of the dog, and results of lab tests to devise a treatment plan.

Allergies develop over time. A dog may eat a food for months, then suddenly develop itching skin, ear inflammation, anal itching, vomiting, diarrhea, or asthma-like coughing, that turns out to be a food sensitivity. There are many commercial dog foods designed to help with dog food sensitivities. Finding the correct one may take awhile, but once you've found a safe food for your pet, all symptoms will disappear.

Flea allergies are a hypersensitivity to the saliva in the flea bite. One bite causes itching lasting 5 to 7 days. Symptoms are biting, scratching, and hair loss from excessive licking. Topical flea medications work after an adult flea has bitten, so this isn't enough for an allergic dog. Treatment is fleas control. Use chemicals sparingly. Too many can be as harmful as the fleas. Oatmeal baths provide temporary relief of itching. Wash dog bedding with every bath. Limit walks, staying away from trails frequented by wildlife. Your vet may prescribe an antihistamine shot for long-term relief or corticosteroids for immediate relief.

Atopy (inhalant) allergies are usually the result of everyday inhalants like dust mites, pollens, and molds. Reduce exposure to dust and pollen by frequent cleaning, air cleaners, and air conditioning. Reduce mold with use of a dehumidifier and cover dirt around house plants with activated charcoal.

Treatments of symptoms includes weekly baths with oatmeal or medicated shampoos for temporary relief of itching. Topical sprays and creams are used for localized itching. Antihistamines are relatively safe. You may have to try different ones to find one that doesn't overly sedate your pet. Not all over the counter antihistamines are safe for dogs. Consult a vet to determine which choices are safe and effective, and at what dosage. Corticosteroids reduce inflammation which reduces itching. It's primarily used short term to relieve severe itching and inflammation. Long term use is discouraged because this medication suppresses the immune system. Omega-3 is helpful to some dogs. It's a natural anti-inflammatory that reduces the amount and effects of histamines and other chemicals released in response to allergies. It's very safe and used in conjunction with antihistamines can reduce the need for corticosteroids.

Immunotherapy stimulates the immune system to decrease the body's reaction. Shots contain small amounts or extracts of the allergen based on results of skin testing. The dog's owner gives shots to the pet at home. They are very effective but slow to work, taking 6-12 months to see improvement.

Dogs suffering from chronic allergies can scratch open sores on their skin which can become infected and require antibiotics. To reduce the need for prescription medications like antibiotics and corticosteroids, develop a dog allergies treatment plan right away.
