What Causes Lower Urinary Tract Problems in Dogs?

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.
