What is canine addisons disease?

Answer 1

Addison's disease is the human medical term that was co-opted by veterinary medicine for hypoadrenocorticism, a disease in which the adrenal glands do not secrete enough hormones. There are several different types of hypoadrenocorticism: low glucocorticoids, low mineralocorticoids and low androcorticoids. Depending on which class of adrenal hormones are deficient, you would need to administer them to your dog; your veterinarian can work with you on determining the proper dosage, route and timing of supplementation.

Answer 2

the dog is not making cortisol, this is the reverse disease of cushings.
