Question: how is cushing's syndrome diagnosed in dogs?
Answer: Cushing's disease can be verified with an adrenocorticotropic hormone (ACTH) stimulation test. For this test, a blood sample is drawn from the patient, then he is given an injection of ACTH, and a second blood test is taken a few hours later. If the dog's cortisol level goes up a little, his adrenal response is normal.
