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.
