How to Get Rid of a Dog's Fistulas

When speaking of fistulas in dogs, it is almost always the perianal, or anus region that is affected. Perianal fistulas are recognized as lesions around the anus that are typically open sores that ooze and become infected. These fistulas are usually the result of sweat and sebaceous glands becoming clogged, and subsequently infected around the anus. Treatment can range from medications to surgery to remove the lesions.

Instructions

  1. Diagnosing

    • 1

      Observe your dog's behavior for increased licking of the anus area. Watch your dog for diarrhea, constipation, bloody stool or pain during defecation. These are all symptoms of perianal fistulas.

    • 2

      Lift your dog's tail and see if you can find any open, red sores around the anus. According to Dr. Holly Nash of Pet Education Online (peteducation.com), you might see bleeding ulcers and foul-smelling discharge. You should have friend hold your dog's head while you do this, in case the dog's tail is tender when you raise it.

    • 3

      Take your dog to the veterinarian for an examination. The veterinarian will take samples of the fistulas to make sure certain bacteria are present.

    Treating Medically

    • 4

      Begin giving your dog antibiotics prescribed by your veterinarian. Metronidazole is often used, or a combination of several antibiotics. Give the pills by mouth as precribed.

    • 5

      Give your dog the presribed oral anti-inflammatory medication, such as the steroid prednisone. The anti-inflammatory will help lower the swelling of the fistulas, and help control pain. Give the pills by mouth as directed, usually with a meal.

    • 6

      Apply topical medication. Put on a latex glove, and smear some medication directly onto the fistulas. These topical medications are often antibiotics, topical steroids, and are immuno-suppressive. Have a friend hold your dog's head while you apply any topical medication to the area.

    Treating Surgically

    • 7

      Take your dog back to veterinarian for a surgical procedure.

    • 8

      Sedation is often used because of the likelihood of pain to the dog.

    • 9

      The veterinarian will either freeze the fistulas with liquid nitrogen, or simply cut out the necrotic tissue from the perianal region.

    • 10

      Follow the post surgical medication instructions given by your veterinarian. This will likely include much of the medical steps above.

    • 11

      Watch your dog for excessive licking after surgery. If the dog will not stop licking, you may have to put a plastic collar on him to prevent further licking and agitation of the surgery area.
