There has been a tremendous amount of research and studies done on dog allergies and their effects on different systems in the body. The main direction for the treatment of dog allergies lies with the identification of specific allergens that occur through inhalation and ingestion. If the dog allergies affect mainly the skin, often extensive intra dermal testing is performed to identify various inhalant allergens that may be effecting the skin sensitivity. Unfortunately this procedure is quite costly and does not identify the cause of why the dog has developed these allergies.

Dog allergies that also can cause skin sensitivities can be created by specific foods that are ingested by the dog. The blood tests that are done to identify the food or foods causing dog allergies are expensive and in my opinion highly in accurate. A food elimination diet is much more accurate and easily performed at home. Please see the article on Food Sensitivities.

Today's veterinarians are merely treating the effects of dog allergies and not their cause. Have you ever wondered why one dog has allergies and another one does not? During my past 50 years of dealing with dog allergies, I have found a regulatory mechanism now called Atypical Cortisol Estrogen Imbalance Syndrome (ACEIS) or as the public refers to it as Plechner’s Syndrome, that does identify the cause of dog allergies and can be identified with a simple blood test.
