Overview

Addison’s disease in dogs is a rare but serious condition affecting your dog's production of vital hormones. Dogs can get Addison's when their autoimmune systems mistakenly attack their adrenal glands. It can also be caused by trauma or treatment for other conditions.

Dogs with Addison's may suffer a serious attack, known as an Addisonian crisis, where they collapse or suffer muscle tremors. These attacks are life-threatening and require urgent veterinary care. Addison’s disease can’t be cured, but medication allows most affected dogs to live healthy, happy lives.
