Benign Prostatic Hyperplasia in Intact Male Dogs: Welfare and Management

Understanding BPH in entire male dogs and the welfare case for surgical neutering.

Key Facts

Over 80% of intact males over 5 years have BPH causing prostate enlargement
Causes difficulty defecating and urinating — a chronic welfare burden
Castration resolves BPH rapidly through testosterone withdrawal
Medical management with finasteride is an alternative when surgery is not appropriate

Welfare Considerations

BPH causes chronic welfare compromise through straining to defecate, perineal hernia formation, and prostatic cysts in advanced disease. Welfare-focused management identifies BPH through routine annual prostate palpation in intact males, initiates castration or medical management when welfare is affected, and monitors for complications. The welfare case for routine castration in dogs without breeding purpose includes BPH prevention as a significant benefit.

What You Can Do

Have intact male dogs over 5 years examined annually with prostate assessment
Consider castration for intact males with BPH — it is curative and prevents further progression
Ask your vet about finasteride if castration is not appropriate for individual dogs
