Urethral Prolapse in Boston Terrier Dogs


Dogs with a prolapsed urethra are observed to constantly lick his genitalia where a reddish mash is protruding. Straining during urination is a common feature.
Many factors have been recognized as possible causes of Urethral Prolapse including urolithiasis (presence of stones within the urinary tract), infection in the urethra, prolonged sexual excitement, and increased intra-abdominal pressure as an effect of Brachycephalic Syndrome.


Treatment involves surgical removal of the prolapsed urethra. Surgery to correct the prolapsed tissue includes castrating the dog before surgical removal of the prolapsed part. Surgery is often indicated for dogs experiencing pain, necrosis, excessive bleeding, and ulceration.

Aftercare involves the fitting of an Elizabethan collar to prevent the dog from licking on the surgical site and inducing post-operative trauma. Antibiotics are prescribed to prevent infections. Estrogen can be given to reduce the frequency of erections. You should limit your dog’s exposure to females for this may induce penile erections. Non-steroidal anti-inflammatory drugs are often prescribed. If the prolapse is caused by the urolithiasis, the stones should be removed by surgery.
