Hyperadrenocorticism (HAC), or Cushing's disease, is a common endocrine disorder in middle-aged to older dogs caused by excess cortisol. It causes increased thirst, urination, appetite, pot-bellied appearance, and skin changes. Diagnosis is complex, requiring multiple tests that are frequently misinterpreted, and treatment selection depends on whether the disease originates in the pituitary gland or adrenal gland.

Multiple overlapping test options (LDDS, HDDS, ACTH stim, urine cortisol:creatinine ratio) are frequently misinterpreted; PDH vs adrenal-dependent HAC requires different treatment. No single test is 100% diagnostic, and each test has different sensitivities and specificities — the right test sequence depends on clinical presentation, and misinterpretation leads to either unnecessary treatment or missed disease.
Correct test sequence interpretation, PDH vs adrenal tumor differentiation, and trilostane vs mitotane selection and monitoring. A specialist can determine whether your dog has pituitary-dependent HAC (treated medically) or adrenal-dependent HAC (may require surgery), and design a monitoring protocol that minimizes the risk of adrenal crisis.
