Canine Hypoadrenocorticism: Addison's Disease
Information and Overview:
Addison's disease is more prevalent in female dogs. Younger dogs age 4-5 years are more commonly affected than older dogs. Any breed of dog can develop Addison's disease. Breeds most represented are Labrador retrievers, Rottweilers, and West Highland white terriers. Known as Canine Hypoadrenocorticism, Addison's disease results from the decreased production of Cortisol and Mineralocorticoid hormones by the adrenal glands. The common symptoms of Addison's disease are not specific, and can include lethargy, weakness, intermittent vomiting, and poor appetite. These symptoms will likely "come and go" throughout the course of the untreated disease. Most animals with Addison's disease will be presented in an "Addisonian Shock" - a severe stage of the disease in which shock and collapse can occur. If a dog is treated successfully for an Addisonian crisis, however, the long-term outlook is excellent, as most dogs can be controlled with oral or injectable medications to replace the deficient hormones
