Dog Addison's Disease Recognition and Management

Addison's disease (hypoadrenocorticism) is a life-threatening endocrine disorder in dogs that is manageable with lifelong treatment. Early recognition prevents Addisonian crises.

Key Facts

Addison's disease results from destruction of the adrenal cortex causing cortisol and aldosterone deficiency
Common in Standard Poodles, Portuguese Water Dogs, Bearded Collies and Nova Scotia Duck Tolling Retrievers
Classic signs include waxing and waning weakness, vomiting, diarrhea, weight loss and shaking
Addisonian crisis presents as acute collapse with life-threatening electrolyte imbalances
Lifelong treatment with desoxycorticosterone pivalate (DOCP) injections and oral prednisolone is effective

Welfare Considerations

Dogs with untreated Addison's disease experience episodes of debilitating weakness and gastrointestinal distress. Addisonian crises are acutely life-threatening. Once diagnosed and stabilized on appropriate medication, most dogs live normal happy lives. Stress dosing during illness or surgery is essential to prevent crisis.

What You Can Do

Seek veterinary assessment for dogs with waxing and waning weakness, GI upset and depression
Request an ACTH stimulation test to confirm Addison's disease if clinical signs suggest it
Administer DOCP injections and prednisolone as prescribed, monitoring electrolytes regularly
Carry injectable dexamethasone for emergency stress dosing if advised by your vet
Alert any treating vet to your dog's Addison's disease before any procedure or hospitalization
