Bacterial infection in the urinary bladder and/or upper part of urethra is called urinary tract infection. Though it can happen in dogs of all ages, generally, old age dogs are more prone to this condition. In such cases, stone formation, prostate disease, and tumors are frequently seen. Additionally, female dogs are more susceptible to bacterial infections of the lower urinary tract than males.
Symptoms of the disease are inflammation of affected tissue and urinary problems. Some dogs with bacterial infections of the lower urinary tract may not show any signs, but many more do. A few of the more common signs include:
Difficulty urinating
Blood in urine (hematuria)
Cloudy or malodorous urine
Frequent urination, but only in small amounts
Urinary incontinence, especially during confinement or at places that are not customary (i.e., locations he has not peed before)
Urination when bladder is touched (occasional)
