Canine Prostatitis

Prostatitis is a bacterial infection of the prostate gland and can occur in an acute (sudden) or chronic (long-standing) form.

It is more common in male dogs that are not neutered.

CAUSES:

Prostatitis can be caused by disease of the urethra (the small tube where urine flows from the bladder through the penis) or by other urinary tract infections.

SIGNS:

Symptoms vary, depending on whether the disease is acute or chronic. Dogs with the acute form will be weaker than those with the chronic condition.

Signs you may notice include:

  • Cloudy or bloody discharge from the penis
  • Abdominal discomfort
  • Stiff gait
  • Weakness
  • Straining to urinate or defecate
  • Vomiting
  • Weight loss

DIAGNOSIS:

Diagnosis is based on your dog's medical history and the following exams:

  • Urine and blood tests
  • Digital rectal exam
  • Abdominal x-rays and ultrasounds
  • Evaluation of seminal or prostatic fluid
  • Prostatic massage and wash

TREATMENT:

Antibiotics are typically given as treatment.

Intravenous fluids may be required in acute prostatitis cases, along with pain medications.

Neutering may also be recommended.

PREVENTION:

Neutering a dog can help prevent prostatitis.

To prevent relapses:

  • Bring your dog for a recheck a week after finishing the medication. Your veterinarian may recommend urine and prostatic fluid cultures to ensure that the infection is no longer in the body.
  • Make sure the urine color is becoming clearer if it was an abnormal color when your pet was ill.

PROGNOSIS:

Although animals are sicker with acute disease, it is generally easier to achieve a complete cure than chronic disease.

Chronic disease is challenging to cure. Dogs with chronic prostatitis are more likely to have continued problems despite therapy.
