What Causes Urinary Tract Infections in Dogs and Cats?
The most common source of urinary infections in pets is fecal contamination and subsequent spread of bacteria up the urinary tract. Common bacteria involved include staphylcoccus, streptococcus, proteus, and E coli.
Which Pets are Most at Risk for Urinary Tract Infections?
Urinary tract infections are more common in dogs than in cats. Overweight pets with extra skin folds are at risk. Some female pets may have inverted vulvas that lead to bacterial buildup and secondary urinary tract infections. Very often, pets with weaker immune systems including geriatric pets as well as those with dental disease will more likely be prone to urinary tract infections. Chronic diseases such as diabetes, Cushing's Disease, cancer, and immune suppressive viruses in cats such as feline leukemia (FeLV) and feline immunodeficiency Virus (FIV) may lead to urinary infections as well. Pets with a history of urine dribbling and involuntary urination also should be evaluated for urinary tract infection prior to starting medications such as Proin (for dogs) for urine incontinence.
