The signs of Cushing’s syndrome in dogs are due to an excess of circulating glucocorticoids, particularly cortisol. Cortisol is a hormone produced in the cortex of the adrenal glands. The normal function of cortisol is to help the body respond to stress and change, and also to prepare the body for the fight or flight response. Cortisol mobilizes nutrients, modifies the body’s response to inflammation and stimulates the liver to raise the blood sugar.
