• Fungal infection

Such as canine candidiasis, mostly caused by long-term use of antibiotics, immunosuppressants or damp living environment.

II. Physiological factors

• Oestrus

Vaginal secretions increase and the vulva swells during the estrus period, which is easy to breed bacteria and cause inflammation.

• Labor and delivery

Trauma to the vulva during delivery, poor sterilization during assisted delivery, and poor discharge of the evil dew after delivery may all lead to infection.

• Mating

Infection can be caused by vulvar mucous membrane damage during mating and unclean genital organs of male dogs.

III. Environment and living habits

• Poor hygiene

Long-term not washing the vulva, living environment damp, feces and urine pollution and so on easy to breed bacteria.

• Foreign body stimulation

Such as foreign bodies in the vagina, tumors, hematomas, etc., can stimulate the vaginal mucosa to trigger inflammation.

• Excessive washing

Excessive use of stimulating lotion or frequent cleaning will destroy the natural defense mechanism of the vagina.

IV. Other Factors

• Genetic factors

Certain dog breeds such as German Shepherd Dogs and Boxers may be prone to primary vaginitis due to heredity.

• Immune factors

Low immunity, long-term use of immunosuppressants, etc., can easily lead to infections triggering vaginitis.

• Improper diet

Diets high in salt, sugar, low protein or food allergies may affect vaginal health.

Such as uterine pus storage, ovarian cysts, urethral stones, etc., can be secondary to vaginitis.

How to Treat Vaginitis in Dogs?

2. Systemic treatment

• Antibiotic treatment

Vaginitis caused by bacterial infection can be treated with appropriate antibiotics. Common antibiotics include penicillin and cephalosporin.

• Antifungal treatment

For vaginitis caused by fungal infection, antifungal drugs can be used for treatment.

• Antiparasitic treatment

For vaginitis caused by parasitic infection, specific anti-parasitic drugs should be used for treatment.

3. Other treatments

• Immunomodulators

For cases of recurrent or chronic vaginitis, your veterinarian may consider using immunomodulators to regulate your dog's immune response to reduce inflammation.

• Laser therapy

Regularly and gently clean your dog's vulva with warm water and a non-irritating lotion to help reduce symptoms and keep it clean. However, please be careful not to use overly harsh lotions or strong cleansing as this may disrupt their natural defense mechanisms.

• Avoid Allergic Foods

Determine if your dog is allergic to certain foods and avoid feeding them to prevent vaginitis triggered by an allergic reaction.
