After taking a bath during the dog's menstrual period, observe the dog's mental state and see if there are any abnormalities in the vaginal secretions. If there are no abnormalities, the owner does not need to worry too much, just clean the vagina regularly and take measures to keep warm.

If your dog appears depressed, has an elevated body temperature, has diarrhea and other abnormal conditions, you need to take your dog to the hospital for examination immediately. If your dog's vaginal secretions are abnormal and your dog often licks his lower body, it means that your dog's vagina is infected and you need to take medication in time.
