Urethral Prolapse and Neoplasia in Dogs

Overview of Canine Urethral Prolapse and Neoplasia

Urethral prolapse describes the protrusion of the lining of the distal or tail end portion of the urethra through the external urethral opening. Urethral neoplasia is cancer of the urethra. Urethral prolapse and neoplasia are most common in dogs, especially English bulldogs and Boston terriers, and most often affects young to middle aged male dogs.

The prolapsed urethra is a red or purple, swollen, doughnut-shaped mass protruding from the distal end of the penis. Urethral cancer most often affects middle aged to older female dogs

Home Care and Prevention

Monitor your dog’s ability to urinate and administer all medication as directed by your veterinarian. Return for follow-up as directed.

Limit your male dog’s exposure to female dogs or situations that predispose to penile erections. Addressing underlying causes at once may help prevent urethral prolapse.
