Addison disease causes life-threatening adrenal crises in dogs. Early diagnosis and lifelong management enable affected dogs to live normal, high-quality lives.
Addison disease causes profound acute welfare harm during crisis events — affected dogs experience weakness, shock-level circulatory compromise, and potentially fatal electrolyte abnormalities that are extremely distressing. The chronic course before diagnosis involves repeated episodes of vague illness that cause ongoing welfare compromise. Diagnosis is often delayed because signs are non-specific — the episodic nature and eventual recovery between episodes can lead owners and veterinarians to underestimate severity. Once diagnosed and stabilized, the welfare picture transforms dramatically — dogs on appropriate replacement therapy live entirely normal lives. The welfare urgency of Addisonian crisis requires immediate recognition and aggressive emergency treatment. Owner education about recognizing crisis signs and having emergency protocols established with their vet enables prompt response.
