Companion Dog Addison's Disease Welfare

Addison's disease (hypoadrenocorticism) is underdiagnosed in dogs but highly treatable - early diagnosis prevents severe welfare crises.

Key Facts

Addison's disease results from destruction of the adrenal cortex causing cortisol and aldosterone deficiency
It is more common in young to middle-aged female dogs and certain breeds including Standard Poodles
Signs include weakness, vomiting, collapse, and weight loss often waxing and waning
Addisonian crisis is a life-threatening emergency requiring immediate intensive care
Lifelong treatment with desoxycorticosterone pivalate injections and oral prednisolone is required
Dogs with Addison's disease generally have excellent quality of life and normal lifespans with treatment

Welfare Considerations

Addison's disease causes episodic suffering and potentially fatal crises when undiagnosed. The disease is often called 'the great pretender' because its signs mimic many other conditions. Diagnosis eliminates all episodic welfare harm with straightforward lifelong management. Owner education about adrenal crisis recognition is essential for welfare between routine appointments.

What You Can Do

Ask your vet about Addison's disease if your dog has recurring episodes of weakness and vomiting
Ensure your Addisonian dog carries emergency identification and your vet's out-of-hours number
Keep a supply of emergency injectable dexamethasone for travel situations
Tell any treating vet immediately that your dog has Addison's disease in any emergency
Monitor for signs of under or over-mineralocorticoid supplementation with regular veterinary checks
