Humans and dogs can both be affected by Cushing's disease. This disease is caused when there is an overproduction of glucocorticoid within the adrenal gland, which is controlled by the pituitary gland. Cushing's disease can be caused when genetic disorders or tumors in the neck start to affect other organs. In dogs, large amounts of steroids are released, leading to excess thirst and water consumption, an increased appetite and hair loss. Depending on the exact location of the disease, treatment may include having your dog undergo surgery to have tumors removed.

Water Consumption
-
Excessive thirst and water consumption by your dog is the most common sign that it may have Cushing's disease. You will notice that your dog drinks water more frequently throughout the day. Panting non-stop may also be a sign of Cushing's disease. Excess water consumption also causes an increase in urination. Some owners may see a dramatic change in their housebroken dog's behavior. This may mean that your dog will need to relieve himself much more often than usual, like waking you up in the middle of the night to go outside. Also, an increase in urination often leads to household accidents.
Appetite
-
An increased appetite is a sign of Cushing's disease. Dogs with this condition tend to eat their food quickly. They will overeat and gorge on food if left unattended. They may also start to eat objects such as rocks and feces. An affected dog may beg for more food and steal food from other pets. Often, dog's with Cushing's disease start to show signs of aggression toward other animals, especially over food. With an increase in appetite, a dog will likely gain a lot of weight. Obesity will only add to the dog's health problems, such as causing canine diabetes mellitus.
Hair Loss
-
Tremendous hair loss is a sign that your dog may have Cushing's disease. Dogs start to lose hair all around the body, but it's more prominent in the joints such as feet and elbows. These areas can also become very dry and infected if not properly treated. The healing and re-growth time will be much slower in dogs with Cushing's. If you suspect any of these signs may be a diagnosis of Cushing's disease in your dog, see your vet immediately. He can recommend surgery to remove tumors or prescribe the most common medication for pituitary problems, called Lysodren.
