If you've ever had a urinary tract infection (UTI), you know how uncomfortable they can be, and they're just as common in dogs as they are in people.

Dogs of any breed can get a UTI, so it's worth knowing the signs early and getting it treated before it leads to bigger problems. Here's what causes a UTI in dogs, the most common signs, and how you can help.

Dog UTI Causes

A UTI is a bacterial infection of the urinary tract, most often caused by E. coli entering the urethra and disrupting its normal pH balance. Female dogs tend to be more prone to UTIs than males, and older dogs or those with diabetes, kidney stones, Cushing's disease, or chronic kidney disease are also more susceptible.

Up to 27% of dogs will experience a UTI at some point in their life. It's common and very treatable, recognizing the symptoms early and getting prompt treatment is usually all it takes to get your dog back to normal.

Common Signs of a UTI in Dogs

Some dogs will show signs of a UTI right away while others will have much more subtle symptoms. Here are some of the most common to be aware of. 

• Urinating in the house.  If a housebroken dog suddenly starts having accidents indoors, something could be wrong.
• Cloudy and strong-smelling urine. A strange smell after urinating is worth a call to your vet. 
• Blood in the urine. One of the more unmistakable signs, check for blood if you suspect an infection.
• Frequent urination in small amounts. More frequent trips outside with less urine each time.
• Straining, whining, or whimpering while urinating. Urinating can become uncomfortable with a UTI.

• Constant licking of the genital area.

• Increased thirst.

• Low energy or fever

If you notice one or more of these, don't wait to schedule a vet visit. Left untreated, a UTI can lead to more serious issues including kidney infection, sepsis, or bladder stones.

Dog UTI Diagnosis 

Your vet will typically start by asking about your dog's drinking habits, diet, and any other symptoms you've noticed, followed by a physical exam that includes feeling the bladder from the outside.

A urine culture is one of the best ways to confirm a UTI. If you can't collect a sample beforehand, your vet can take one during the visit, it's quick and usually well-tolerated. The sample is cultured to identify the specific bacteria involved, and can also reveal urine crystals, glucose (a sign of diabetes), or bladder parasites.

Dog UTI Treatment

Treatment depends on severity. Most cases clear up with a course of antibiotics matched to the bacteria found in the urine culture. More advanced cases may need additional tests to determine whether bladder stone removal or a diet change is necessary, and antimicrobial treatment courses typically run three to six weeks. Make sure your dog has plenty of water at home to help flush the bladder during recovery.

Preventing UTIs in Dogs

Talk to your veterinarian about the best prevention plan for your dog. A few general tips:

• Regular potty breaks. Holding their urine in for too long can lead to a UTI.
• Fresh drinking water every day. Water quality matters for flushing bacteria out of the system.
• A healthy diet. A well-balanced diet supports overall urinary and general health.
• Routine grooming and bathing. Pay attention to the skin and fur around the urethra opening to help prevent infections.
