Hi, I have a 10 week old Boston Terrier which I'm trying to train to ring the bell hanging from the door knob so he can do his thing. He's very smart and has learned how to ring the bell only after I showed him twice upon exiting to go pee. Well, he's using the bell to signal playtime outside instead now and although I appreciate the fact that he hasn't used a pee pad for about a week, did I train him incorrectly or is this normal for puppies when they get bored inside?
