It is natural for dogs to be excited when they smell the smell of menstrual blood, because dogs are also in estrus during their menstrual period. The smell of menstrual blood will attract male dogs, and male dogs will feel very excited, which is normal. If you have a male dog at home, be sure to fasten a leash when taking the dog out to prevent the dog from running around; if it is a female dog, it is best to wear safety pants, which is hygienic and safe.
