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.


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.


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:


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


Antibiotics are typically given as treatment.

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

Neutering may also be recommended.


Neutering a dog can help prevent prostatitis.

To prevent relapses:


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.
