Cushing’s disease is referred to as hyperadrenocorticism in which the pituitary gland produces excess cortisol. In some dogs, any problem in the adrenal glands may also cause a rise in cortisol. The major culprit is any form of tumors in both glands.
The symptoms are very similar to diabetes which may include:
Excess thirst
Increase in appetite
Increased urination
Lethargy
Hair loss
