    ASPCA logoThere are many problems that can affect a dog’s lower urinary system. Incontinence, bladder stones or crystals in the urine, bacterial infections, cancer, trauma or even obstruction of the urethra, the tube that allows urine to pass from the bladder to the outside of the body, can occur.

    What Causes Lower Urinary Tract Problems in Dogs?

    • Stones, crystals or debris accumulation in the bladder or urethra
    • Bladder inflammation or infection
    • Incontinence from excessive water drinking or weak bladder/hormonal issue
    • Trauma
    • Cancer
    • Stress
    • Spinal cord abnormalities
    • Congenital abnormality
    • Prostate disease

    What Health Conditions Might Lead to Lower Urinary Tract Problems?

    The most common lower urinary tract disease in dogs over seven years of age is incontinence related to a weak urinary sphincter muscle, allowing urine to “leak” out. Bacterial infections are also common. Endocrine diseases such as adrenal disease and diabetes mellitus can predispose dogs to bacterial infection of the lower urinary tract.

    Which Dogs Are Prone to Lower Urinary Tract Problems?

    Older female dogs and dogs with diabetes are especially prone to urinary tract problems. There are different types of bladder stones that have a tendency to form under different conditions-some in older dogs, some in either males or females, and some in specific breeds under certain circumstances.

    How Can I Tell if My Dog Has Urniary Tract Problems?

    • Inability to urinate or only passing a small amount of urine
