Urine Infections in Dogs

Urinary infections in dogs are quite common and can be unpleasant and painful due to the burning sensation when urinating. Fortunately, once diagnosed and treated by a veterinarian, these infections clear up quickly, and your canine companion will soon return to their usual self.

If you're curious about the symptoms of urinary tract infections (UTIs) in dogs and want information on treatment options, continue reading this guide.

What Are Urine Infections in Dogs?

A urinary infection in a dog affects the urinary tract, making it uncomfortable to pass urine. Your dog may strain while urinating and their urine may contain blood. These UTIs are typically caused by bacteria such as E. coli but can also result from fungi or bladder stones. Incontinence in older dogs can also lead to an infection.

Surprisingly, urinary tract infections in dogs are more common than you’d think. According to American Kennel Club, it’s one of the most common infectious diseases in dogs and around 14% will be affected by this problem at some point in their lives. 

Are Some Dogs More Predisposed to Urine Infections Than Others?

Any dog can develop a urinary infection; however, older dogs and female dogs (due to shorter urethras) are more susceptible. Additionally, dogs with pre-existing health conditions like chronic kidney disease and Cushing's disease are at higher risk.

Symptoms of Urine Infections in Dogs

If your dog has a urine infection, they may display some of the following signs: 

• Difficulty urinating – they may appear like they’re straining and might whimper
• Urinating frequently – they may also dribble urine
• Forgetting their housetraining – they might start urinating in the house again
• Blood in dog urine – it may appear as a pinkish color or be cloudy
• Frequent licking – they may constantly lick around the urinary opening
• Fever – your dog may feel hot, and a fever may be present
• Bad odor – the urine may also have a strong smell to it
• Increased thirst – due to the more frequent urination, your dog may drink more often to try and restore their bodily fluids
• Fatigue – your dog may seem more tired or sluggish than usual 

If you suspect a urinary infection in your dog, take them to the vet for diagnosis. Untreated infections can lead to complications such as lower urinary tract dysfunction, kidney or bladder stones, blood poisoning, and even kidney infections.

Diagnosing Urine Infection in Dogs

The vet will inquire about your dog's symptoms and conduct a thorough examination, which may include taking a urine sample for culture to identify any bacteria involved.

Treatment of UTIs in Dogs

Once diagnosed with a urinary infection caused by bacteria, antibiotics are usually prescribed to clear up the infection.

To ensure your dog's full recovery, follow the recommended antibiotic dosage for the prescribed duration. Stopping treatment too early can cause the infection to reappear. If the infection persists, consult your vet for alternative treatment options.

Preventing UTIs in Dogs

There’s no cure for UTIs in dogs, but you can take steps to reduce the risk:

• Ensure your dog always has access to plenty of fresh, clean water.
• Let them outside often to relieve themselves so they’re not forced to hold urine for too long.
• Keep their private regions clean. If you have a long-haired dog it may be a good idea to keep the feathering around their rear end cut shorter as this prevents the fur from becoming soiled, thus reducing the risk of infection.  

If you suspect your dog has a urinary infection, take them to the vet immediately. UTIs in dogs can be painful and uncomfortable, so early treatment is essential for your pet's well-being.
