Hyperadrenocorticism (Cushing's disease) causes dogs to overproduce cortisol, leading to a cluster of distressing symptoms that are often misattributed to normal aging.
Cushing's disease profoundly affects dog welfare through chronic discomfort, muscle weakness, skin infections, and compromised immunity. Many dogs go undiagnosed for years because owners attribute symptoms to old age. Early diagnosis and treatment restore energy and comfort, markedly improving wellbeing.
