Recognizing early signs, understanding treatment options, and implementing preventative measures are key to keeping your pet healthy.

At Lewiston Veterinary Clinic, we are committed to providing expert care for pets experiencing urinary issues, ensuring they receive timely and effective treatment.

What is a Urinary Tract Infection (UTI) in Pets?

A UTI occurs when bacteria enter the urinary tract, leading to inflammation and infection. The urinary tract includes:

  • Kidneys – Filter waste and produce urine
  • Ureters – Carry urine from the kidneys to the bladder
  • Bladder – Stores urine until elimination
  • Urethra – Carries urine out of the body

If left untreated, UTIs can spread to the kidneys, causing serious complications such as pyelonephritis (kidney infection) or sepsis (systemic infection).

Causes of UTIs in Dogs and Cats

Several factors can contribute to UTIs, including:

  • Bacterial infections – The most common cause, often due to coli or other bacteria entering the urethra
  • Weakened immune system – Older pets or those with underlying conditions like diabetes are more susceptible
  • Urinary stones or crystals – Can block urine flow and create an environment for bacteria to thrive
  • Poor hygiene or grooming issues – Especially in long-haired breeds or pets with mobility issues
  • Inadequate water intake – Leads to concentrated urine, increasing infection risk

Recognizing the Symptoms of a UTI in Pets

Common Signs of UTIs

  • Frequent urination in small amounts
  • Straining or pain while urinating
  • Blood in the urine (hematuria)
  • Strong-smelling or cloudy urine
  • Accidents in the house or inappropriate urination
  • Lethargy or decreased appetite

If your pet is showing severe symptoms like vomiting, fever, or extreme discomfort, seek veterinary care immediately. A complete urinary blockage (more common in male cats) is a life-threatening emergency.

Diagnosing Urinary Tract Infections in Pets

At Lewiston Veterinary Clinic, we use advanced diagnostic tools to accurately diagnose and treat UTIs:

  • Urinalysis – Examines urine for bacteria, blood, crystals, and pH balance
  • Urine culture and sensitivity test – Identifies the specific bacteria causing the infection and determines the most effective antibiotic
  • Ultrasound or X-rays – Detects urinary stones, tumors, or structural abnormalities
  • Blood tests – Checks kidney function and rules out underlying conditions like diabetes

Treatment Options for UTIs in Pets

Once a UTI is diagnosed, treatment typically includes:

  • Antibiotics – Prescribed based on the specific bacteria identified in the urine culture
  • Pain management – Anti-inflammatory medications may help relieve discomfort
  • Increased hydration – Encouraging water intake helps flush out bacteria
  • Dietary changes – Some pets benefit from prescription urinary health diets to reduce infection risk

It’s critical to complete the full course of antibiotics as prescribed, even if symptoms improve, to prevent recurrence and antibiotic resistance.

FAQs About UTIs in Pets

Can I treat my pet’s UTI at home?

No, UTIs require veterinary treatment with antibiotics. Home remedies may temporarily ease symptoms but won’t eliminate the infection.

How long does it take for a UTI to clear up in pets?

Most pets show improvement within 3-5 days of starting antibiotics, but the full course (usually 7-14 days) must be completed to prevent recurrence.

Can UTIs be a sign of something more serious?

Yes. Recurrent UTIs may indicate underlying conditions like diabetes, bladder stones, or kidney disease. Your veterinarian may recommend additional tests if infections keep returning.
