Treatment for vaginitis in dogs depends on the underlying cause. For juvenile vaginitis, often no treatment is necessary as it resolves after the first heat cycle. For adult onset vaginitis, treatment may include antibiotics for bacterial infections, surgical removal of foreign bodies, or managing structural abnormalities such as vaginal strictures. Vaginal douches (0.05% chlorhexidine or 0.5% povidone-iodine solutions) are performed twice per day to help clear the infection. Conservative treatment is often the first approach, but surgical treatment may be necessary for severe cases. Addressing any contributing factors like poor hygiene or excess skin folds is crucial. Regular monitoring and maintaining cleanliness can help prevent vaginitis. Veterinary medicine might involve a complete blood count, bacterial culture, and sometimes surgical intervention for severe cases. Ensuring your dog maintains a healthy weight, as overweight dogs are more prone to infections, can also help prevent recurrence. Understanding your dog's history, including any previous infections or estrous cycle irregularities, is essential for effective treatment.
