Dog Prostate Disease and Welfare

Prostatic disease in entire male dogs causes significant discomfort and health problems, with castration being the most effective prevention and treatment.

Key Facts

Benign prostatic hyperplasia (BPH) affects up to 80% of entire male dogs by age 5
Prostatic disease causes difficulty urinating and defecating, and may cause pain
Brucella canis infection can cause prostatitis with systemic illness and is a zoonotic concern
Prostatic carcinoma is rare but has a poor prognosis regardless of neutering status
Castration rapidly resolves BPH and prevents most forms of prostatic disease

Welfare Considerations

BPH causes chronic discomfort from difficulty passing urine and faeces. Prostatic abscesses cause acute severe pain and systemic illness. The discomfort of established prostatic disease may be tolerated for extended periods before owners seek veterinary attention. Castration is a definitive, highly effective treatment for most prostatic conditions except carcinoma. Medical management with finasteride provides an alternative for breeding dogs but is less reliably effective.

What You Can Do

Consider castration for entire male dogs to prevent prostatic disease
Seek veterinary assessment if your entire male dog shows straining to urinate or defecate
Monitor entire male dogs regularly for prostatic abnormalities through rectal palpation
Discuss medical alternatives to castration with your vet if breeding is planned
Be aware of brucellosis risk from entire male dogs used for breeding
