Pet Incontinence

Incontinence in Pets

Dog and Toilet Paper

Urinary incontinence is a house-trained dog or a litter box-trained cat losing control of its bladder. Incontinence can affect pets of any gender, age, or breed, but some of the following dog breeds are prone to it1,2:

Dog Breeds Prone to Incontinence

Cocker Spaniels, Springer Spaniels, Doberman Pinschers, Old English Sheepdogs, Boxers, German Shepherds, Giant Schnauzers, Irish Setters, Rottweilers, Weimaraners

Incontinence should not be confused with house-training challenges or submissive urination ("stress incontinence"). (Stress incontinence, which can happen in young dogs, follows the normal biological voiding process.)3

Possible causes of urinary incontinence in dogs and cats include1,4:



Prostate Disorders

Some additional signs of urinary incontinence in female dogs include discomfort or behavioral changes, scalding of the skin or severe eczema, and (in severe cases) an offensive odor.

Hormone-related incontinence3

In middle-aged to older spayed females, a hormonal imbalance can cause incontinence. One out of 5 spayed female dogs can be affected by incontinence, which usually develops about 3 years after the surgery.5 About 30% of female dogs that develop urinary incontinence also weigh more than 45 lbs.6

It is seen less frequently, but is also possible, in young females and older neutered males. Hormonal incontinence is caused by a deficiency of estrogen (in females) or testosterone (in males). Both of these hormones are important in maintaining muscle tone of the urethral sphincter.

Hormone therapy, such as Incurin® for spayed female dogs, can help treat incontinence due to hormonal imbalance.

Urethral muscle-related incontinence1

Some treatments and surgeries, or collagen injections can help strengthen the urethral muscles that control your pet's flow of urine.

Spinal cord incontinence1

Your veterinarian may recommend surgery for a protruding disc.

Congenital abnormalities1

Your veterinarian may recommend surgery to correct any congenital abnormalities that are causing urinary incontinence in your pet.
