Prostatic Disease in Dogs: Welfare and Management

Understanding prostatic conditions in intact and neutered male dogs to protect welfare.

Key Facts

Benign prostatic hyperplasia affects the majority of intact male dogs by age 6
Prostatitis causes systemic illness — fever, pain, and urinary and defecation difficulty
Castration resolves BPH rapidly and is the most effective long-term management
Prostatic carcinoma is rare but occurs in both intact and neutered dogs

Welfare Considerations

Prostatic disease causes welfare compromise ranging from mild dysuria to severe systemic illness. Welfare-focused management of BPH uses castration as definitive treatment — medical management with finasteride is an alternative when castration is not appropriate. Prostatitis requires aggressive antibiotic treatment and supportive care. Regular veterinary assessment of intact older male dogs reduces the welfare burden of undetected prostatic disease.

What You Can Do

Have intact male dogs examined annually from age 5 — include prostatic assessment
Consider castration of intact dogs with BPH — it is curative and safe
Investigate fever or signs of urinary difficulty in intact male dogs promptly
