What is Cushing's Disease

Cushing’s disease, or hyperadrenocorticism, occurs when a dog’s body produces an excess of the hormone cortisol. Cortisol is crucial for normal body function, but an overproduction can lead to health issues.

Types and Causes of Cushing's Disease

Two main types: Pituitary-dependent (85%) and Adrenal-dependent (15%)
