Well when our dogs have an accident we say "Bad Girl" and put them outside well we clean the mess and when the come inside they expect a treat and dont get it. Thats our way of no violence punishment. I have been over at peoples houses and they hit there animals for having an accident! I never hit my dogs if they have an accident on the floor.. If they are sick then we let it go. Its the right thing to do lol But our dogs barley have accidents they are trained to ring a bell attached on our back door if they want out.
