Canine Prostate Disease: Welfare in Entire Male Dogs

Prostate disease is common in entire male dogs over 5 years of age. Benign prostatic hyperplasia, prostatitis, and prostatic cysts all cause welfare impacts that are largely preventable through neutering.

Key Facts

Benign prostatic hyperplasia (BPH) affects approximately 80% of entire male dogs over 5 years
Clinical signs include straining to defecate, ribbon-shaped faeces, haematuria, and haematospermia
Prostatitis causes fever, pain, and lethargy in addition to urinary signs
Neutering (castration) causes complete regression of BPH within weeks and prevents recurrence

Welfare Considerations

BPH causes chronic discomfort from prostatic enlargement pressing on the rectum and urethra. Straining to defecate is a significant welfare indicator — affected dogs may spend prolonged periods attempting defecation with significant visible effort and discomfort. Prostatitis causes acute systemic illness with fever and abdominal pain. Deslorelin implants (Suprelorin) provide temporary testosterone suppression as an alternative to surgical castration in dogs where anaesthesia carries risk. Welfare-positive management requires prompt recognition and treatment.

What You Can Do

Monitor entire male dogs over 5 years for signs of straining to defecate or changes in urination pattern
Discuss neutering or medical management with your vet at annual health checks for entire males over 5 years
Seek veterinary attention promptly if your entire male dog shows fever, abdominal pain, or acute urinary signs
Consider deslorelin implants as a reversible medical alternative to surgical castration for prostatic disease management
