Dog Cushing's Disease: Welfare and Quality of Life

Hyperadrenocorticism (Cushing's disease) in dogs causes chronic symptoms that significantly impair quality of life but are manageable with appropriate treatment.

Key Facts

Cushing's disease involves excess cortisol from pituitary tumor (80-85%) or adrenal tumor (15-20%)
Signs include increased thirst/urination, pot-bellied appearance, hair loss, panting, and muscle weakness
Untreated Cushing's disease causes chronic discomfort and predisposes to infections and blood clots
Trilostane (Vetoryl) is the primary treatment, significantly improving quality of life in most dogs
Treatment requires regular monitoring - overdose can cause life-threatening Addisonian crisis
Adrenal tumor cases may require surgery; pituitary cases are managed medically in most dogs

Welfare Considerations

Cushing's disease causes a constellation of chronic symptoms that significantly reduce quality of life - panting, weakness, skin problems, and excessive thirst create ongoing discomfort. Many owners attribute these changes to 'normal aging' rather than treatable disease. With appropriate diagnosis and treatment, most Cushing's dogs experience substantial symptom improvement and extended comfortable life. The welfare imperative is accurate diagnosis and managed treatment rather than accepting progressive deterioration.

What You Can Do

Discuss Cushing's disease testing with your vet for any middle-aged to older dog with increased thirst and pot belly
Understand the monitoring requirements before starting trilostane - regular cortisol testing is essential
Learn to recognize signs of Addisonian crisis: weakness, collapse, vomiting, diarrhea after treatment changes
Maintain consistent medication timing - irregular dosing increases complication risk
Monitor for secondary complications including urinary tract infections and skin infections
