Accidents in the House? How Do I Know if My Dog Has a UTI

Your fully house-trained dog just had an accident on the floor. Or they've been asking to go outside every 45 minutes. Or you noticed them squatting for a long time and not producing much.

Before you blame your dog, it might be worth considering a UTI. UTIs in dogs are common, treatable, and easy to miss until the signs become hard to ignore.

What Is a UTI in Dogs?

A urinary tract infection, or UTI, happens when bacteria enter your dog’s urinary tract and multiply. This can affect the bladder (cystitis), the urethra, or in more serious cases, the kidneys. Female dogs are more susceptible than male dogs because of anatomical differences in the urethra, though male dogs can get UTIs too.

What Are the Signs of a UTI in Dogs?

The symptoms of a dog bladder infection or UTI often look like this:

• Frequent urination or straining to urinate
• Accidents in the house from a dog that's otherwise reliable
• Blood in the urine
• Foul-smelling urine
• Excessive licking of the genital area
• Increased thirst or drinking more water than usual
• Lethargy, low energy, or restlessness
• Difficulty urinating or producing very small amounts

Some dogs show several of these at once. Others have just one or two. Female dogs sometimes show almost no symptoms until the infection has been going on for a while.

What Else Could Be Causing These Symptoms?

A UTI is the most common explanation, but it's not the only one. Bladder stones, kidney infections, diabetes, and in male dogs, prostate disease can all produce similar symptoms. Bladder tumors are less common but worth ruling out, especially in older dogs.

That overlap is exactly why a urinalysis matters. The symptoms alone don't tell the whole story. Here are some other issues that could be causing these symptoms in your dog:

• Bladder Stones: Crystals or stones in the bladder can cause straining, blood in the urine, and frequent urination, symptoms that look almost identical to a UTI. Bladder stones and infections can also occur at the same time.
• Kidney Infections: An infection that has traveled up to the kidneys is more serious than a bladder infection and may come with fever, back pain, and lethargy alongside the urinary symptoms.
• Kidney Disease: Chronic kidney disease can increase thirst and urination frequency, which sometimes gets mistaken for a behavioral issue before the underlying cause is identified.
• Diabetes: Dogs with diabetes often drink and urinate far more than usual. If your dog's increased thirst and urination aren't accompanied by other UTI symptoms, diabetes is worth ruling out.
• Prostate Disease: Male dogs with prostate issues can have difficulty urinating and may strain in a way that looks similar to a UTI.
• Bladder Tumors: Less common, but bladder tumors can cause blood in the urine and straining. Worth ruling out, particularly in older dogs.

How Do Vets Diagnose a UTI in Dogs?

The standard first step is a urinalysis, which tests the urine for bacteria, white blood cells, crystals, and other markers of infection. A urine culture identifies the specific bacteria involved and which antibiotic will work best against it.

Depending on what's found, your vet may also recommend x-rays or an ultrasound to check for bladder stones, blood tests to evaluate kidney function, or other diagnostics to rule out underlying conditions.

How Is a Dog UTI Treated?

For a straightforward UTI, treatment is usually a course of antibiotics targeted to the bacteria causing the infection. Most dogs start feeling better within a few days of starting antibiotics, though the full course needs to be completed to clear the infection completely. Additional treatment may include:

• Anti-inflammatory medications or pain management if your dog is uncomfortable
• Prescription diets if bladder stones or crystals are contributing to the problem
• Encouraging water intake to help flush the urinary tract

For recurring UTIs, your vet will want to look more closely at potential underlying causes like poor hygiene, anatomical factors, or conditions like diabetes or chronic kidney disease.

When Should You Head to Scout Pet Urgent Care?

Come in if your dog is showing any of the signs listed above. Scout Pet Urgent Care handles this type of visit all the time:

• Your dog is straining to urinate or having accidents inside the house
• You've noticed blood in the urine
• Your dog seems uncomfortable, restless, or is licking at their genitals more than usual
• Symptoms have been going on for more than a day and aren't improving
• Your dog is also showing signs like lethargy, increased thirst, or fever

Your Scout veterinarian will recommend next steps with transparency and clarity. Then, together, you and your veterinarian will make the best choice for you and your pet.

When Is It an Emergency?

Most UTIs are urgent care situations, not emergencies. But there's one exception. If your dog cannot urinate at all, this is a urinary blockage and it's a medical emergency, especially in male dogs.

A blocked urinary tract is painful and life-threatening. Go directly to an emergency animal hospital. Scout Pet Urgent Care will always refer you to emergency care if your pet's situation calls for it.

Frequently Asked Questions

Can a dog's UTI go away on its own?

It's possible but unlikely. Most UTIs require antibiotics to fully clear. Waiting too long can let the infection spread to the kidneys, which makes treatment more involved.

Are female dogs more likely to get UTIs?

Yes. Female dogs are more susceptible because their urethra is shorter and wider than in male dogs, which makes it easier for bacteria to reach the bladder.

Is blood in my dog's urine always from a UTI?

Not necessarily. Blood in the urine can come from a UTI, bladder stones, bladder tumors, or trauma. A urinalysis is the first step toward figuring out the cause.

How do I collect a urine sample from my dog?

Your vet can collect a urine sample in the clinic, or you can try catching a midstream sample at home in a clean container. Ask your vet's office which method they prefer before your visit.

Can I prevent UTIs in my dog?

Encouraging plenty of water intake, keeping up with routine vet checkups, and maintaining good hygiene can all help. Dogs on immunosuppressive medications or with certain underlying conditions may need more frequent monitoring.
