Vaginitis in Dogs

The term vaginitis refers to inflammation of vagina or vestibule in female dogs. Although this conditions is uncommon, it may occur at any age and in any breed.

Symptoms and Types

  • Discharge from the vulva
  • Male attraction (due to vaginal discharge)
  • Frequent urination (polyuria), even in improper locations
  • Frequent licking of the vagina (due irritation caused by inflammation)

Causes

Vaginitis may occur due to feces or urine contamination of the organ or collection of blood at the site. An injury to the vagina or abscess formation may also lead to vaginitis. Other common underlying causes include:

  • Urinary tract infections (viral or bacterial)
  • Vaginal tumors
  • Zinc poisoning
  • Problems with urinating

Diagnosis

After completing a complete medical history of your animal, your veterinarian will perform a physical exam, including a blood chemical profile, a complete blood count, a urinalysis, and an electrolyte panel. Although the results of these tests may be normal, there are exceptions. In some dogs, the urinalysis may indicate inflammation, while biochemical testing may indicate abnormally high hormones, a sign of uterine inflammation or pregnancy.

To rule out neoplasia, foreign bodies, and/or constriction of reproductive tubes, your veterinarian may recommend abdominal X-rays. Ultrasounds can also be of great help in diagnosing vaginal masses.

A sample from the vagina may be gathered for further testing. For instance, it may be cultured and microscopically examined or it may be sent to a laboratory to identify whether pus, blood, or feces is present in the sample.

Your veterinarian will also examine the inside of vagina -- either with his/her finger or a special instrument called a vaginal scope -- to rule out the presence of a mass, tumor, foreign body, blood-filled cavity, or abnormal narrowing of vagina.

Treatment

Unless there is some serious underlying problem such as a tumor, foreign body, etc., a dog rarely requires hospitalization or surgery for vaginitis. In the case of bacterial infection, your veterinarian will prescribe antibiotics. Antiseptics may also be administered via the vagina to help control the infection locally.

If the inflammation occurs before puberty should take place, it usually resolves after the first estrus (heat) and no treatment is required. Otherwise, the complete removal of the ovaries and uterus may be recommended in some dogs, especially if the condition is not medically treatable.

Living and Management

If your dog has undergone surgery, she might feel sore for few days. Typically, your veterinarian will prescribe pain-killers to alleviate the pain. Good nursing care and a stress-free environment will promote a speedy recovery.

Follow-up examinations are used to evaluate the progress of treatment. However, the overall prognosis largely depends on the underlying cause of the vaginal inflammation.
