What is it?
• Hyperadrenocorticism is the name given to the condition in which there is an overproduction of cortisol or other glucocorticoid hormones
• Most affected dogs are in their middle or older age

What causes it?
• Pituitary-dependent hyperadrenocorticism occurs when a tumor in the pituitary gland causes an increase in the production of ACTH, which causes the adrenal glands to become overactive
• Common symptoms include increased thirst, appetite, or urination, obesity, muscle weakness, lethargy, thinning of coat, heat intolerance, and urinary tract or skin infections

What tests are needed?
• Because clinical signs are specific for this disease, extensive laboratory tests must be performed
• Routine tests may show high levels of liver enzymes, cholesterol, blood sugar, and/or white blood cells
• Screening tests are available to measure cortisol levels and usually require blood samples
• Test results may not be clear cut, so often Cushing’s Disease may be tough to diagnose

How is it treated?
• There are a number of medications available to treat Cushing’s Disease such as milotane or trilostane
• Tumors may be removed through use of radiation or surgery

What follow up care is needed?
• Repeated laboratory testing is necessary to monitor the status of the condition
• Pet owners should research and understand the side effects to any drugs that are administered
• The disease may shorten the dog’s overall lifespan, but most improve with therapy
