What Are the Symptoms of an Enlarged Prostate in Dogs?

Dogs may suffer from an enlarged prostate, or prostatomegaly, because they are not neutered. Symptoms of an enlarged prostate may become evident in dogs as young as three years. Enlargement often occurs as a result of the growth of benign cysts in the prostate. Infection is another cause. Neutering your dog usually relieves all symptoms.

  1. Strain During Bowel Movements

    • The prostate is located directly below the rectum. When the prostate becomes enlarged, it pushes against the rectum, making it difficult for the dog to defecate. If you notice that your dog is straining or seems to be in pain when it has a bowel movement, it may be suffering from an enlarged prostate.

    Abnormal Gait

    • An enlarged prostate may also cause your dog to walk strangely to avoid anything rubbing the prostate and causing increased pain. You may notice that your dog walks with its back legs straight and stiff, and takes small steps.

    Discharge

    • Check your dog for any kind of discharge from its penis. If your dog has an enlarged prostate, you may notice blood or pus.

    Bladder Issues

    • Urination may also be a problem for your dog. In addition, bladder infections are common when a dog has an enlarged prostate.

    Abnormal Behavior

    • Monitor your dog's behavior carefully. If it has an enlarged prostate, it may not be eating to avoid painful bowel movements. Your canine may be unusually fatigued and uninterested in play.

    Diagnosis and Treatment

    • Your veterinarian will perform a number of tests to diagnose the cause of your dog's symptoms. A rectal exam will allow your veterinarian to determine the size of the prostate. A urine sample may also be necessary. The best treatment for an enlarged prostate is neutering, because this removes the hormones that cause the prostate to grow.
