Causes of urine leakage in spayed female dogs

Updated on February 18, 2012

The decision to have the dog spayed can be a dog owner’s answer to the call of breeding fewer dogs to lessen the number of homeless dogs that have to be put to sleep every year. Aside from supporting the efforts to solve a national problem, spaying or neutering dogs would give the pet a better chance to live healthier and longer lives. However not many dog owners are aware that spaying the dog can result to urinary incontinence. A dog owner will just be surprised to see the housebroken dog wet the bed, have accidents on the carpet and on the furniture after the ovariohysterectomy was done. Does your dog have this condition too? Have you ever wondered why the urine of your spayed dog is leaking?

What is urine leakage?

Urine leakage, also known as urinary incontinence is a bladder or urination control issue. The dog may leak while sleeping so that urine spots will be noticed in the beddings. The rear end of the dog will be constantly wet and there will always be a stench of urine coming for its genital area. Although this condition can affect any breed of dogs, some breeds like the Collie, Dobermans and Boxers are more susceptible. This condition is commonly noticed in spayed dogs. Urinary incontinence in intact females is from 0 to 1% while it is about 20% in spayed dogs. Studies have noted that the incidence of urine leakage usually sets in after the dogs are spayed.

Urethral Sphincter Mechanism Incompetence

There are a number of factors that help in the development of urinary incontinence. The size of the body, the position of the bladder and obesity are other contributing factors. Urethral Sphincter Mechanism Incompetence is the most common cause of urinary incontinence in spayed dogs. 

Hormonal imbalance

Spaying is a surgical procedure that removes the uterus and the ovaries of the dog. This procedure affects the production of hormones. Studies conducted have shown that after a dog is spayed, the level of estrogen is considerably decreased. How will this affect the dog’s ability to control urination? At the base of the bladder and urethra are smooth muscles that control the flow of urine. The strength of the muscle tone is maintained by estrogen. The decrease in the level of this hormone results to the weakening of the muscle tone and consequently will cause urine to leak.


To address the urine leakage, the normal function of the urethral sphincter muscle must be restored. This can be done through surgery or through hormone replacement therapy. Diethylstilbestrol is administered as replacement for estrogen. Homeopathic and herbal remedies are gaining acceptance from dog owners as aside from being reasonably priced, these remedies have no side effects.
