Many signs of Cushing's disease in dogs overlap with normal ageing, making diagnosis challenging. Knowing the differences ensures welfare issues are identified and treated promptly.
The misattribution of Cushing's disease signs to normal ageing is a significant welfare problem because it delays treatment during which the dog experiences unnecessary suffering. Chronic excess cortisol causes skin fragility, muscle pain from wasting, skin infections, and urinary discomfort. Dogs with untreated Cushing's are often less comfortable than their owners realise. Veterinary screening at annual health checks for middle-aged and older dogs from predisposed breeds would improve early detection rates and treatment outcomes, reducing the welfare burden of the disease.
