FACTS EVERY DOG BREEDER SHOULD KNOW
Thyroiditis The Subtle Disease
While just one individual symptom may not alert the breeder to a significant genetic problem, a combination of the symptoms should signal the need to test for autoimmune thyroiditis.
The most common clinical symptoms of canine autoimmune thyroiditis are listed below:
The incidence of autoimmune thyroiditis in males and females is similar. Therefore it is equally important to test both prior to breeding.
Thyroiditis Can Be Asymptomatic
Dogs with autoimmune thyroiditis produce antibodies against the storage form of thyroid hormone. These antibodies are present in the dog’s bloodstream, so a simple blood test is all that is needed for accurate diagnosis.
The best available technology for early detection of autoimmune thyroiditis in dogs is a sensitive assay for THYROGLOBULIN AUTOANTIBODY (TgAA). A commercial kit for TgAA analysis is now manufactured by Oxford Laboratories, and is now available to veterinary laboratories worldwide. The TgAA assay has been recommended by the Orthopedic Foundation for Animals (OFA) for its canine thyroid registry. In the United States and Canada, your veterinarian can have your dog’s blood tested by an approved veterinary laboratory. This OFA registry records and stores data concerning the incidence of autoimmune thyroiditis. The importance of this is that it (1) enables more complete genetic counseling and (2) ‘provides data for research purposes.
