Desensitization for Dog Allergies
You have several treatment options if your dog suffers from allergies. Traditional treatments include steroids, allergen avoidance and desensitization. Desensitization helps your dog become immune to the allergens that normally trigger a reaction.

Description
-
Desensitization, or immunotherapy, involves injecting your dog with an allergen to increase his immune response. First your dog is tested to determine the allergen causing his symptoms. Then a lab will create an injection that includes the allergen. Your vet will administer the injections on a scheduled basis until your dog builds a tolerance for the allergen.
Testing
-
Your vet must determine the exact allergen that triggers your dog's allergies before desensitization injections begin. With an Intradermal Skin Test (IDST), your dog is injected with potential allergens, and his reactions are noted. Since there are many possible allergens, your dog may need repeated tests for an accurate diagnosis.

Administration
-
Desensitization injections are initially administered in small amounts, and the dose increases over time. Your dog will receive injections every one to two days. Your vet may show you how to administer the shots at home.
Effectiveness
-
Desensitization is effective in 60 to 80 percent of allergic dogs. Your dog's improvement will be gradual, so you may not notice a difference in his symptoms until three to six months after the treatment begins. For allergy symptom relief in the meantime, you can use fatty acid supplements, antihistamines, topical ointments and shampoos.
Precautions
-
You should follow the desensitization injection schedule carefully. Do not alter it without consulting with your vet because any slight changes can affect your dog's progress. After your dog receives an injection, monitor him for up to three hours. If you notice any reactions, contact your vet.
