Signs of UTI in Dogs: How to Tell If Your Dog Has a Urinary Tract Infection

How Common Are UTIs in Dogs?

Urinary tract infections are one of the most common bacterial infections in dogs, affecting up to 14% of dogs at some point in their lives. Female dogs are significantly more prone than males. Catching a UTI early means faster treatment and less discomfort for your dog.

10 Signs of UTI in Dogs

1. Frequent Urination

Your dog needs to go outside much more often than usual — sometimes every 30–60 minutes. This urgency is caused by bladder inflammation irritating the urge to urinate even when the bladder is nearly empty.

2. Straining to Urinate

Your dog squats or lifts their leg for a long time but produces only a small amount of urine, or nothing at all. Straining with no urine output in a male dog is a potential urinary blockage — a life-threatening emergency. Go to the vet immediately.

3. Blood in Urine

Pink, red, or brown-tinged urine indicates blood — a classic sign of UTI or bladder stones. Even a small amount of blood in urine warrants a vet visit.

4. Accidents in the House

A house-trained dog that suddenly starts having accidents indoors is often experiencing urgency they can't control. This is one of the most common ways owners first notice a UTI.

5. Cloudy or Strong-Smelling Urine

Healthy dog urine is pale yellow and has a mild odor. Cloudy urine or urine with an unusually strong, pungent smell indicates bacterial infection.

6. Excessive Licking of the Genital Area

Dogs with UTIs often lick their genital area excessively due to discomfort and irritation. This is especially noticeable in female dogs.

7. Whimpering or Crying When Urinating

Vocalization during urination indicates pain — a clear sign of bladder inflammation or infection.

8. Lethargy or Loss of Appetite

Mild lethargy can accompany a UTI, especially if the infection is more significant. Significant lethargy, fever, or loss of appetite may indicate the infection has spread to the kidneys.

9. Dribbling Urine

Involuntary dribbling of urine — especially when resting or sleeping — can indicate a UTI, hormonal incontinence (common in spayed females), or bladder stones.

10. Increased Water Intake

Some dogs with UTIs drink more water than usual. Significantly increased thirst combined with frequent urination can also indicate diabetes — which increases UTI risk. See our guide on signs of diabetes in dogs.

UTI vs. Bladder Stones: How to Tell

Bladder stones cause very similar symptoms to UTIs — straining, blood in urine, frequent urination. The only way to distinguish them is with a vet examination, urinalysis, and X-ray or ultrasound. Both conditions often occur together.

Signs of Kidney Infection (More Serious)

If a UTI spreads to the kidneys (pyelonephritis), symptoms become more severe:

• Fever (above 103°F)
• Back or flank pain (dog hunches or flinches when you press near the kidneys)
• Significant lethargy
• Vomiting
• Loss of appetite

Kidney infection requires urgent veterinary treatment.

When to See a Vet

Any suspected UTI warrants a vet visit for urinalysis and appropriate antibiotic treatment. Do not attempt to treat a UTI with home remedies alone — bacterial infections require antibiotics to fully resolve.
