How to clean the bitch during the first estrus and keep the dog clean and healthy?

Don't bathe it at this time. You can buy diapers for dogs or wear them with human underwear. Cut a hole in the back and take out the tail. You can put sanitary napkins in it, so that the house won't be everywhere. It's best not to let it mate during the first estrus, which is not good for the bitch.
