How to Tell if Your Dog Has a UTI: Symptoms Guide
There’s nothing quite like the panic that sets in when you notice your beloved pup acting a little off. If your dog has been making more frequent trips outside than usual, or you’ve spotted something unusual in their bathroom habits, you might be wondering: could it be a urinary tract infection? UTIs are surprisingly common in dogs, affecting both males and females across all age groups, and catching the signs early can make all the difference in getting your furry friend the help they need.
A urinary tract infection in dogs is caused by bacteria invading the urinary system, and while it’s definitely uncomfortable for your pooch, the good news is that UTIs are highly treatable when caught early. The tricky part? Dogs can’t exactly tell us when something’s wrong, so we have to play detective and watch for those telltale signs. In this comprehensive guide, we’ll walk you through everything you need to know about recognizing UTI symptoms in dogs, understanding what causes them, and knowing when it’s time to call the vet.
Whether you’re dealing with a senior pup, a young troublemaker, or anything in between, understanding how to spot a UTI could save your dog weeks of discomfort and prevent the infection from becoming something more serious. Let’s dive into the symptoms, risk factors, and what you can do to help your four-legged friend feel better.
Common Signs Your Dog Has a UTI
The most obvious indicator that your dog might have a UTI is a sudden change in their bathroom habits. If your previously housetrained pup is suddenly having accidents in the house, that’s your first red flag. This isn’t about discipline or regression—it’s your dog’s way of signaling that something’s amiss with their urinary system. They may not be able to hold it as long as they normally do, or they might feel the urge to go much more frequently than usual.
You might also notice that your dog is straining to urinate or producing only small amounts of urine despite frequent trips outside. Some dogs will squat or assume their usual bathroom position but produce little to nothing, or they may circle and re-position multiple times. This straining is particularly telling because it suggests discomfort or urgency in the urinary tract. Additionally, if your dog seems to be drinking more water than usual, this could be another piece of the puzzle, as increased thirst often accompanies UTIs.
One of the most alarming signs—and one that absolutely warrants an immediate vet visit—is blood in the urine. If you notice pink, red, or brownish-tinged urine, or if you spot blood droplets where your dog has been, that’s a clear indication something serious is happening. We’ve got a detailed guide on why your dog might be peeing blood that can provide more context, but any blood in the urine should never be ignored.

Behavioral Changes to Watch For
Beyond the obvious bathroom-related signs, UTIs can cause significant behavioral shifts in your dog. Many dogs with urinary tract infections become noticeably more lethargic or withdrawn. Your normally playful pup might lose interest in their favorite toys, decline invitations to go for walks, or spend more time resting than usual. This change in energy levels is your dog’s way of telling you they’re not feeling their best.
Anxiety and restlessness are also common behavioral indicators. Your dog might seem anxious about going to the bathroom, whining or crying before, during, or after urination. They may also display signs of discomfort by constantly licking their genital area—more than their normal grooming routine. Some dogs become more clingy or seek extra attention from their owners, while others may become irritable or snap more easily than they normally would.
You might also notice your dog asking to go outside more frequently than their established schedule, even in the middle of the night. If your senior dog who’s been reliably sleeping through the night suddenly needs bathroom breaks at 2 AM, that’s worth investigating. Similarly, a dog who typically has solid nighttime control might start having accidents in their crate or bed, which is particularly distressing for them since dogs naturally dislike soiling their sleeping areas.
Physical Symptoms and Changes
Beyond behavioral changes, there are several physical symptoms that can accompany a UTI. The urine itself may have a stronger, more pungent odor than usual. Some owners describe it as smelling particularly foul or ammonia-like, which is caused by the bacterial infection. The color might also change—cloudy urine is a classic sign of a UTI, and as mentioned, any discoloration or blood warrants attention.
Fever is another physical symptom to monitor. If your dog seems unusually warm to the touch or is displaying other signs of illness, checking their temperature might be helpful. We have a complete guide on how to tell if your dog has a fever that walks you through the process. A normal dog temperature ranges from 101 to 102.5 degrees Fahrenheit, so anything above that could indicate infection.
Some dogs with UTIs also experience loss of appetite or seem less interested in treats they normally love. Combined with lethargy, a decreased appetite can indicate that the infection is causing systemic discomfort. In some cases, dogs may also experience mild abdominal discomfort, though this is harder to detect without professional examination.

When to Call Your Veterinarian
Here’s the bottom line: if you suspect your dog has a UTI, it’s time to call your vet. UTIs don’t resolve on their own, and while they’re not always emergencies, they do require professional attention. The sooner you get your dog checked out, the sooner you can start appropriate treatment and get them back to feeling normal.
You should seek emergency veterinary care if your dog is showing signs of extreme distress, has blood in the urine, is unable to urinate at all despite trying, or has a high fever. If your dog seems to be in severe pain or is vomiting, don’t wait for a regular appointment—head to an emergency clinic. These could be signs of a more serious condition like a blocked urethra or kidney infection, which require immediate intervention.
For less urgent situations—like occasional accidents and increased bathroom trips without other alarming signs—a regular veterinary appointment is appropriate. Your vet will likely want to collect a urine sample to confirm the infection and may recommend starting treatment right away. Having information about when the symptoms started and what changes you’ve noticed will be incredibly helpful for your vet’s diagnosis.
Risk Factors and Vulnerable Dogs
While any dog can develop a UTI, certain factors make some pups more susceptible than others. Female dogs are statistically more prone to UTIs than males due to their anatomy—their urethra is shorter and wider, making it easier for bacteria to travel up into the bladder. This doesn’t mean male dogs are immune, but it’s worth knowing if you have a female pup.
Senior dogs are another high-risk group. As dogs age, their immune systems become less effective at fighting off infections, and they may have other underlying health conditions that increase UTI risk. Dogs with diabetes, Cushing’s disease, or kidney problems are also more vulnerable to urinary tract infections. Additionally, dogs who are overweight or obese may be at increased risk due to reduced mobility and potential complications with their urinary system.
Dogs with a history of UTIs are more likely to develop them again, so if your pup has had one before, you’ll want to be extra vigilant about watching for symptoms. Certain breeds may also have predispositions, and dogs with anatomical abnormalities are at higher risk. If your dog has any of these risk factors, maintaining regular vet checkups and being proactive about any changes in their bathroom habits is especially important.
Diagnosis and Testing
When you take your dog to the vet with suspected UTI symptoms, the diagnosis process is typically straightforward. Your vet will ask detailed questions about your dog’s symptoms, when they started, and any other changes you’ve noticed. They’ll perform a physical examination, which may include palpating your dog’s abdomen to check for pain or discomfort in the bladder area.
The most common diagnostic tool is a urinalysis, where your vet will examine a urine sample under a microscope and perform chemical tests. This test can detect the presence of bacteria, white blood cells, and other abnormalities that indicate a UTI. Your vet may also perform a urine culture, which takes a few days but identifies the specific type of bacteria causing the infection and determines which antibiotics will be most effective.
In some cases, your vet might recommend additional imaging like an ultrasound or X-rays, particularly if your dog has recurrent UTIs or if they suspect there might be an underlying structural problem. These additional tests help rule out complications like bladder stones or tumors that could be contributing to the infection.
Treatment Options Available
The standard treatment for a bacterial UTI is antibiotics. Your vet will prescribe an antibiotic based on the type of bacteria identified in the urine culture, and it’s absolutely critical that you complete the full course of antibiotics as prescribed, even if your dog seems to feel better after a few days. Stopping early can allow the infection to return stronger and potentially lead to antibiotic resistance.
Most dogs start feeling noticeably better within a few days of starting antibiotics, but the infection may not be completely cleared. Your vet might recommend a follow-up urinalysis after the antibiotic course is complete to confirm the infection is gone.

Beyond antibiotics, supportive care is important. Make sure your dog has constant access to fresh, clean water—this helps flush the urinary system. Take your dog out frequently to urinate, as this also helps flush bacteria from the system. Some people add supplements to their dog’s diet, and there’s interesting research on whether dogs can have cranberries, which have been traditionally used to support urinary health in both humans and dogs.
If your dog is experiencing abdominal discomfort or upset stomach from the infection or antibiotics, you might wonder what you can give a dog for upset stomach. Always check with your vet before giving any supplements or remedies, especially while your dog is on antibiotics, as some can interfere with medication effectiveness.
According to the American Kennel Club’s guide on UTIs, most uncomplicated UTIs respond well to antibiotic treatment within 7-10 days. However, some infections can be more stubborn, particularly if they’re caused by resistant bacteria or if there’s an underlying issue complicating recovery.
Frequently Asked Questions
How long does it take for a dog UTI to go away with antibiotics?
Most dogs show improvement within 3-5 days of starting antibiotics, but the full course typically lasts 7-14 days depending on the severity and the specific antibiotic prescribed. It’s essential to complete the entire course even if symptoms disappear, as stopping early can lead to recurrence and antibiotic resistance. Your vet may recommend a follow-up urinalysis to confirm complete resolution.
Can a dog UTI go away on its own?
Unfortunately, no. Unlike some minor infections in humans, canine UTIs caused by bacteria require antibiotic treatment. While a dog might seem to recover temporarily, the infection typically persists and can worsen, potentially spreading to the kidneys. This is why veterinary care is essential.
What’s the difference between a UTI and a bladder infection in dogs?
A UTI (urinary tract infection) is a general term that encompasses any bacterial infection in the urinary system, which includes the kidneys, ureters, bladder, and urethra. A bladder infection (cystitis) is specifically an infection of the bladder, so all bladder infections are UTIs, but not all UTIs are bladder infections. Kidney infections are more serious and require immediate attention.
Are male or female dogs more prone to UTIs?
Female dogs are significantly more prone to UTIs due to their shorter and wider urethra, which makes it easier for bacteria to ascend into the bladder. However, male dogs can absolutely develop UTIs, and when they do, it’s sometimes more serious because the infection has to travel farther, potentially reaching the prostate or causing complete urinary blockage.
Can I prevent UTIs in my dog?
While you can’t prevent all UTIs, you can reduce the risk by ensuring your dog has constant access to fresh water, taking them out frequently for bathroom breaks, and maintaining good hygiene, particularly for female dogs. Regular vet checkups help catch early signs, and maintaining a healthy weight supports overall urinary health. According to the ASPCA, proper hydration and regular urination are key preventative measures.
Should I be worried if my dog has had multiple UTIs?
Recurrent UTIs can indicate an underlying issue that needs investigation. Your vet may recommend additional diagnostic testing like ultrasound or X-rays to check for bladder stones, tumors, or anatomical abnormalities. According to VCA Animal Hospitals, dogs with recurrent infections may benefit from preventative measures or further investigation into root causes.
What should I do if my dog refuses to take their antibiotic?
Contact your vet immediately. They may be able to prescribe a different formulation (like liquid instead of pills) or recommend ways to administer the medication. Some vets can crush tablets and mix them with food, though this should only be done with your vet’s approval. Never skip doses or stop treatment early, as this compromises your dog’s recovery.
