When do dogs start having bladder issues? Let’s Explore

Causes of Urinary Incontinence in Dogs

There are many causes of incontinence in dogs, including:Â

  • Urinary tract infection
  • Anatomic abnormalities
  • Weak bladderÂ
  • Spinal injury or degeneration
  • Inherited medical condition that occurs at or before birth
  • Hormonal imbalance
  • Prostate disorders
  • Diseases that cause excessive drinking of water, for example, diabetes, kidney disease, and Cushing’s disease
  • Some medications, like corticosteroids
  • Urinary stones
  • How is urinary incontinence diagnosed in dogs?

    Incontinence can be confused with diseases and infections that cause a pet to urinate frequently. The tests performed to evaluate a pet with incontinence depend upon the age of the pet and clinical signs.

    A dye study of the bladder is usually performed, and it is common to collect a urine sample for bacterial culture and to see if the urine is dilute or shows evidence of an infection that could be the cause of incontinence.

    Blood tests can detect evidence of kidney damage from infection or for the presence of diseases that might lead to increased urine production.

    X-rays or ultrasounds may be used to look at the parts of the urinary tract.

    What causes urinary incontinence in dogs?

    Pets can be incontinent for many reasons, including abnormalities in parts of the brain and spinal cord that control bladder function, birth defects, and disease. As pets age, they may become incontinent because muscles that hold urine in the bladder weaken.

    Incontinence in young animals is often caused by a birth defect known as ectopic ureter(s). The ureters carry urine from the kidneys to the bladder, and if one or both ureters bypass the bladder and connect to an abnormal location, such as the urethra or vagina, the puppy may drip urine.

    Hormone-responsive incontinence occurs in neutered dogs of both sexes but most commonly in female dogs. The pet can urinate normally, but they leak urine while resting. Hormone-responsive incontinence can occur months to years after a pet is neutered.

    Dogs with brain or spinal cord disease may either dribble urine or be unable to pass urine. Most often they will have other signs of nervous system disease, such as muscle weakness or paralysis.

    Vulvovaginal stenosis, a condition in which the vagina at the level where the urethra ends is narrowed, is a less common cause of incontinence in female dogs. Occasionally when the pet urinates, some urine will get trapped in the vagina in front of this narrowed area. Then when they rise after lying down the urine pours out.

    Older pets can also develop senility and simply be unaware they are dribbling urine.
