How to Tell If Your Dog Has a UTI: Signs, Causes, and When to See a Vet
Urinary tract infections (UTIs) are one of the most common urinary issues dogs experience, and they can be uncomfortable if left unaddressed. As a pet parent, it’s helpful to understand the early signs of a potential UTI, what might cause it, and when it’s time to contact your veterinarian. While UTIs can affect dogs of any age or breed, knowing what to look for helps you respond quickly and support your dog’s overall wellness.
What Is a UTI in Dogs?
A urinary tract infection occurs when bacteria enter the urinary system (most often the bladder) and begin to multiply. Dogs normally flush out bacteria when they urinate, but if the bacteria aren’t cleared, an infection can form. UTIs require veterinary diagnosis and care, so recognizing early symptoms is essential.
Common Signs Your Dog May Have a UTI
Dogs can show several behavioral or physical changes when something isn’t right with their urinary system. Here are the most common symptoms pet parents tend to notice:
1. Frequent Urination
Needing to urinate more often than usual is one of the most noticeable signs. Your dog may ask to go outside more frequently or have trouble holding it between walks.
2. Straining or Discomfort While Urinating
If your dog seems to push, take longer than usual, or appear uncomfortable during urination, it may be a sign that something is irritating the bladder or urethra.
3. Accidents in the House
A dog who is well-trained may suddenly have accidents indoors because of increased urgency or discomfort.
4. Strong Odor or Changes in Urine Appearance
Cloudy urine, darker color than normal, or a stronger scent can signal an issue in the urinary tract. In some cases, you might even notice traces of blood.
5. Excessive Licking
Dogs may lick the genital area more frequently when they are uncomfortable or irritated.
6. Behavioral Changes
Irritability, restlessness, or seeming “off” can accompany urinary discomfort. Some dogs become less active or avoid activities they normally enjoy.
Not all dogs show every symptom. Some show only subtle signs, which is why monitoring changes in routine is important.
Common Causes of UTIs in Dogs
UTIs can develop for a variety of reasons, including:
- Bacteria Entering the Urinary Tract: This is the most common cause and can occur from environmental exposure, grooming habits, or bacteria that naturally live on the skin.
- Weak Urinary Immune Defenses: Dogs may be more susceptible to UTIs if the body isn’t effectively clearing bacteria during urination.
- Poor Hydration: Dogs who don’t drink enough water may urinate less frequently, giving bacteria more time to multiply in the bladder.
- Incomplete Bladder Emptying: If a dog isn’t fully emptying their bladder, bacteria have a greater chance of growing.
- Age and Sex Factors: Female dogs can be more prone to UTIs due to a shorter urethra, but male dogs can experience them too. Senior dogs may also be more susceptible.

How Vets Diagnose a UTI
A veterinarian typically performs a urinalysis to examine pH levels, crystals, bacteria, and other markers of infection. They may also culture the urine to identify the specific bacteria present. Because UTIs share symptoms with other urinary concerns, proper testing is essential for accurate diagnosis.
When to See a Veterinarian
It’s always a good idea to reach out to your vet if you notice:
- Frequent accidents or sudden changes in urination
- Straining or crying while urinating
- Blood in the urine
- Persistent licking or discomfort
- Changes lasting more than 24–48 hours
UTIs don’t resolve on their own and require veterinary treatment. Prompt care helps prevent the infection from becoming more severe or spreading to other parts of the urinary system.
How to Support Your Dog’s Urinary Health Long-Term
While only a veterinarian can diagnose and treat UTIs, you can help support your dog’s urinary wellness through simple daily habits:
- Keeping fresh water available at all times
- Encouraging regular bathroom breaks
- Maintaining consistent grooming and hygiene
- Monitoring any changes in bathroom routine
- Scheduling routine checkups with your veterinarian
Paying attention to your dog’s normal habits makes it easier to spot changes early.
Keeping Your Dog Comfortable and Healthy
Recognizing the early signs of a potential UTI can make a meaningful difference in your dog’s comfort and overall well-being. By paying attention to changes in urination habits, behavior, and daily routines, you’re able to spot issues sooner and seek the veterinary guidance your dog needs. Consistent hydration, regular bathroom breaks, and routine checkups all play an important role in supporting a healthy urinary system. When something feels off, trusting your instincts and consulting your veterinarian is the best way to keep your dog feeling their best.
