What is a Urinary Tract Infection?

Urinary tract infections in pets occurs frequently causing urination to be extremely painful and uncomfortable. These infections are caused by bacteria that enter the urethra (the tube connecting the bladder to the exterior of the body through which urine flows), bladder or any part of the urinary tract.

Bladder stones, some underlying diseases, overuse of medications, bladder tumors or cancer or abnormalities of the urinary tract can also increase the risk of urinary tract infections. Urinary tract infections affect both dogs and cats, although they tend to be more common in cats.

Female cats and dogs experience more episodes of urinary tract infections because the urethra is shorter and broader than in males. If left untreated urinary tract infections can lead to more serious health complications such as kidney infections.

  • Straining to urinate
  • Urinating with pain
  • Licking of the genitals
  • Cloudy or blood urine

What Causes Urinary Tract Infections?

Diagnosing Urinary Tract Infections

The diagnosis of urinary tract infections are based on the symptoms, medical history and a physical examination. A urine test will be performed to check for a high ph balance, the presence of bacteria, crystals, red and white blood cells. Additional tests such as a urine culture, blood tests, x-rays and ultrasound may be performed if recurring infection occur or to determine the cause of underlying diseases or abnormalities.

In more severe cases or with persistent urinary tract infections, surgery or catheterization may be recommended by your vet.
