Dog Addison's Disease Management

Addison's disease is a life-threatening hormonal condition in dogs that, once diagnosed and treated, allows most affected dogs to live comfortable normal lives.

Key Facts

Addison's disease occurs when the adrenal glands fail to produce sufficient cortisol and aldosterone
It is called the 'great pretender' for its diverse and nonspecific symptoms
An Addisonian crisis without treatment can be rapidly fatal from electrolyte imbalances
Treatment requires daily medication and periodic injections for lifelong management
Dogs with Addison's disease need supplemental stress doses of steroids during illness or surgery
Standard Poodles, Portuguese Water Dogs, and Bearded Collies have higher prevalence

Welfare Considerations

Addisonian dogs before diagnosis experience episodes of extreme weakness, vomiting, collapse, and the physiological crisis of inadequate stress hormones. The diagnosis is often delayed because symptoms are episodic and diverse. Once diagnosed and stabilized, most Addisonian dogs do extremely well on treatment and live normal quality lives. The welfare concern centers on the period before diagnosis when crises cause suffering, and on ensuring owners understand the medication requirements to prevent future crises.

What You Can Do

Be alert to waxing and waning weakness, vomiting, and collapse in susceptible breeds
Insist on electrolyte testing in dogs with recurrent gastrointestinal and weakness episodes
Follow medication protocols strictly and never abruptly stop steroids in Addisonian dogs
Carry a medical alert card and extra medications when traveling with Addisonian dogs
Ensure all vets treating your Addisonian dog know about their condition before any procedure
