What Are the Causes of UTI in Canines?

by Shanon Ottaway

Overview

A urinary tract infection (UTI) begins in the urethra but can travel into a dog's bladder and kidneys and affect other organs. If your dog is urinating frequently, experiencing discomfort when urinating, has urine that is dark or cloudy, is licking his genitals excessively or his abdomen is tender, he may have a UTI.
Is It Serious?

A UTI can become dangerous, especially if left untreated. It could lead to incontinence, prostatitis, septicemia and kidney disease or failure. It is also uncomfortable and painful, so it is important to treat your dog's UTI right away.

Dog Food

Dog food or water that has been contaminated with bacteria can cause a UTI. Commercial foods could be contaminated, but you should also be careful to store them properly and don't add water to the food or let it sit out for a long period of time.
Other Causes

In addition to the ingestion of bacteria, a UTI could be caused by bladder stones, tumors, Cushing's disease or diabetes. Certain medications can also lead to a UTI.
Males vs. Females

Female dogs are more likely than male dogs to develop a UTI. This is due to the shorter length of their urethra; bacteria do not have to travel as far to reach the bladder.
Treatment

If you think your dog has developed a UTI, make an appointment with your veterinarian. She can prescribe an antibiotic to help take care of the infection, and you can discuss alternative forms of treatment and prevention (such as cranberry extract pills) with her.
