Dog Addison's Disease: Adrenal Insufficiency Care

Addison's disease causes adrenal insufficiency in dogs, requiring lifelong treatment but offering excellent prognosis with proper management.

Key Facts

Hypoadrenocorticism (Addison's disease) is caused by destruction of the adrenal cortex
Young to middle-aged females of certain breeds including Standard Poodles and Portuguese Water Dogs are predisposed
Signs include lethargy, vomiting, weakness, and waxing-waning illness that mimics many conditions
Addisonian crisis with severe electrolyte imbalance can cause collapse and death without emergency treatment
Diagnosis confirmed by ACTH stimulation test showing failure to produce cortisol
Lifelong treatment with monthly DOCP injections and daily oral prednisone provides excellent control
Dogs on treatment live normal, full lives with good quality of life

Welfare Considerations

Addisonian crisis is a medical emergency causing severe weakness, shock, and death without treatment. The 'great pretender' nature of Addison's means dogs often suffer through multiple veterinary visits before diagnosis. Once diagnosed and stabilized, the welfare outlook is excellent - most dogs return to full normal activity. The main ongoing welfare risk is an Addisonian crisis if medication is missed or during physiological stress.

What You Can Do

Seek urgent veterinary evaluation for dogs with episodic severe weakness, vomiting, and collapse
Know the signs of Addisonian crisis: severe lethargy, vomiting, trembling, and rapid deterioration
Always inform vets about an Addison's diagnosis as additional stress-dose steroids are needed for illness or surgery
Never run out of prednisone - refill prescriptions before the supply runs low
Carry an emergency prednisone supply and information card about your dog's diagnosis
Connect with Addison's support groups for guidance on management during illness or stress
