Dog Prostatic Disease: Welfare and Treatment

Prostatic diseases in intact male dogs including benign prostatic hyperplasia, prostatitis, and prostatic carcinoma cause significant welfare compromise requiring appropriate management.

Key Facts

Benign prostatic hyperplasia (BPH) affects the majority of intact male dogs over 5 years of age
BPH causes difficulty defecating and urinating, and prostatic pain that affects walking
Prostatic infection (prostatitis) causes fever, depression, and severe pain requiring antibiotic treatment
Prostatic carcinoma in dogs is uncommon but aggressive, with poor prognosis regardless of neuter status
Castration is curative for BPH and prevents the condition entirely when performed early

Welfare Considerations

Prostatic disease causes significant chronic discomfort from a gland that directly interfaces with the urinary and digestive tracts. Benign prostatic hyperplasia causes constipation, straining, and the discomfort of an enlarged gland pressing on surrounding structures. Prostatitis adds fever and acute pain to this picture. Castration resolves BPH definitively and rapidly, with the prostate shrinking to a fraction of its enlarged size within weeks of surgery. Medical management with osaterone acetate provides an alternative for owners who decline surgery. The welfare case for early neutering in dogs not intended for breeding is strengthened by BPH prevention as a long-term welfare benefit.

What You Can Do

Monitor intact male dogs for signs of BPH including difficulty defecating or straining to urinate
Discuss castration or medical management options with your veterinarian for dogs showing prostatic signs
Seek urgent veterinary assessment for any intact male dog showing fever and reluctance to walk
Consider early neutering of dogs not intended for breeding to prevent prostatic disease development
