Urinary tract infections (UTIs) are a common ailment affecting approximately 14% of the canine population at some point in their lives. While older dogs (7 years and up) are more frequently diagnosed, younger pups can also develop UTIs. All breeds are susceptible, though female dogs are more prone than males due to their shorter urethras, allowing bacteria to ascend more quickly. Signs my male dog has a uti.
What is a Urinary Tract Infection in Dogs?
A dog’s bladder is typically a sterile environment, free from bacteria. However, bacteria can enter the bladder through the urethra, the tube that carries urine from the bladder out of the body. Once inside, these bacteria can multiply and colonize the urinary tract, leading to an infection.
Recognizing the Signs and Symptoms of UTIs in Dogs
Dogs with UTIs may not always exhibit obvious symptoms, but when they do, key indicators include:
- Increased thirst and urination: Excessive drinking and frequent, small urinations.
- Changes in urine: Bloody, cloudy urine, or urine with a strong odor.
- Behavioral changes: Licking excessively around the genital area, acting uncomfortable or distressed while urinating, or lethargy.
- Appetite and energy: Lack of appetite and a general decrease in energy levels.
- Fever: An elevated body temperature.
- Incontinence: Difficulty holding urine for normal periods.
Certain conditions and treatments can put dogs at a higher risk for UTIs. These include diabetes, endocrine or hormonal disorders like Cushing’s Disease, and dogs undergoing chemotherapy or immunosuppressive drug therapy. Long-term use of cortisone-type medications also increases risk. For these dogs, regular urine tests are often recommended by veterinarians to monitor for infections.

Causes of UTIs in Dogs
Bacteria, often from the area surrounding a dog’s genitalia and the environment, can travel up the urethra into the bladder, causing infection. E. coli is a common culprit, but various other bacteria can also be responsible. A weakened immune system, common in very young, elderly, or ill dogs, makes it harder for the body to fight off these infections. If left untreated, the infection can spread to the kidneys, potentially leading to more severe issues like pyelonephritis (kidney infection), kidney stones, or even kidney failure.

Are Certain Dogs More Prone to UTIs?
While any dog can develop a UTI, some factors increase susceptibility. Female dogs are more likely to be affected than males. Dogs with pre-existing health conditions like chronic kidney disease or Cushing’s disease are also at a higher risk.
Diagnosing a UTI in Dogs: Urinalysis and Urine Culture
Diagnosing a UTI involves collecting and testing a urine sample. A urinalysis (UA) examines the urine’s chemical properties and allows for visual inspection for crystals, cells, or bacteria. This can be done in-house by your veterinarian or sent to an external laboratory, with results typically available within 24 hours.
Common UA findings in dogs with UTIs may include an excess of white blood cells, the presence of bacteria under a microscope, or excess protein in the urine. However, if a dog drinks a lot of water, the urine may be too diluted to detect abnormalities. Therefore, a urine culture is often necessary to confirm an infection. This test involves incubating the urine sample to encourage bacterial growth, confirming the presence of infection and helping determine which antibiotics will be effective. Urine culture results usually take 3 to 5 days.
UTIs can be classified as uncomplicated or complicated:
- Uncomplicated UTIs: This is typically the first infection in an otherwise healthy dog and is usually treatable with a short course of antibiotics.
- Complicated UTIs: These occur due to an underlying anatomical or functional abnormality in the urinary tract, leading to persistent or recurrent infections. Conditions like pyelonephritis, bladder stones, or prostatitis fall into this category. Addressing the underlying cause is crucial for resolving a complicated UTI. Signs of a uti in a male dog.
Recurrent UTIs, defined as three or more occurrences within a 12-month period, can be classified as reinfection or relapse:
- Reinfection: The UTI returns within 6 months of treatment completion, caused by a different bacterial organism.
- Relapse: The infection is caused by the same bacteria as a previous episode and occurs within 6 months of completing treatment.
Treatment and Recovery for UTIs in Dogs
Treatment for UTIs varies depending on the type and severity.
- Uncomplicated UTIs: Typically treated with a 7- to 14-day course of antibiotics. While improvement should be noticeable within days, completing the full course as prescribed by your veterinarian is crucial. A follow-up urine culture is recommended about a week after treatment to ensure the infection is cleared.
- Complicated or Recurrent UTIs: These may require longer treatment courses, often 3 to 6 weeks, though shorter courses of 10-14 days can be effective with the right antibiotics. Veterinarians may recommend re-culturing urine both during and after antibiotic treatment to monitor effectiveness.
During treatment, increasing your dog’s water intake is important to help flush bacteria from the urinary tract. While some owners explore natural remedies, there’s no scientific evidence they can cure UTIs, and some human remedies may be unsafe for dogs. Always consult your veterinarian if you suspect a UTI, as symptoms can mimic other serious health conditions.
Is there a cure for UTIs in dogs?
Yes, urinary tract infections in dogs can be effectively cleared with antibiotics.
Are UTIs contagious?
No, UTIs in dogs are not contagious to humans or other pets.
Cost of Treatment
The cost of treating a UTI can vary based on geographic location, veterinary fees, the type and duration of antibiotics, and necessary diagnostic tests like urinalysis and urine cultures. Costs can range from approximately $25 for antibiotics to several hundred dollars for diagnostic tests.
Recovery and Management Tips
Recovery time depends on infection severity. Most uncomplicated cases resolve quickly with treatment. To aid recovery and prevent recurrence:
- Hydration: Ensure constant access to fresh, clean water. Incorporating wet food into the diet also contributes to water intake.
- Medication Compliance: Administer all prescribed medications on schedule and complete the entire course, even if symptoms improve.
- Regular Potty Breaks: Allow frequent opportunities for urination to prevent holding urine for extended periods.
- Monitor for Improvement: If your dog shows no improvement after 48 hours of starting treatment, contact your veterinarian.
Potential Complications of Untreated UTIs
If left untreated, UTIs can lead to more serious health problems, including kidney infections (pyelonephritis) and the formation of struvite bladder stones. Bladder stones, often correlated with UTIs, can cause significant pain and predispose dogs to further infections. Seeking veterinary care promptly for suspected UTIs is essential.
Preventing UTIs in Dogs
Preventing UTIs involves several key practices:
- Fresh Water: Provide clean water daily to help flush bacteria.
- Grooming: Regular grooming of the urinary opening and bathing can help prevent bacterial entry.
- Potty Breaks: Offer frequent opportunities for urination.
- Diet: Feed a healthy, well-balanced diet.
- Probiotics and Vitamin C: Probiotic supplements can support healthy gut bacteria, and Vitamin C can bolster the immune system (consult your vet before administering Vitamin C due to potential effects on urine pH).
- Regular Check-ups: Routine veterinary visits can help identify and address potential issues early.
There is currently no vaccine available for urinary tract infections in dogs.
When UTI Symptoms Indicate a More Serious Issue
UTI symptoms can overlap with more severe conditions. If your dog exhibits any of the following, seek immediate veterinary attention:
- Bloody Urine: While a UTI symptom, it can also indicate poisoning, kidney disease, trauma, cancer, or bladder stones.
- Difficulty Urinating: This is a medical emergency and can signal urinary tract obstructions, scar tissue, spinal cord issues, trauma, cancer, or prostate disease.
- Changes in Urination Habits: Abrupt changes, such as accidents in the house or increased frequency, can be linked to diabetes, hypothyroidism, Cushing’s disease, cancer, trauma, or UTIs.
In Summary
Urinary tract infections are common in dogs and may not always present with clear symptoms. When symptoms do occur, such as frequent urination, passing small amounts of urine, or increased thirst, prompt veterinary treatment is crucial to prevent complications like kidney infections and alleviate discomfort. Preventive measures like ensuring adequate hydration, regular potty breaks, and routine veterinary care can significantly help minimize the risk of UTIs.
