When Kaji use to mark, I would double clap to get his attention and follow it with a firm "no". I didn't yell, but it was a firm no. A belly band is a piece of material that goes around the dogs belly covering his Mr Peeps. The idea behind it is it catches any pee when they try to mark, thus protecting your house and items from getting marked. In my opinion, if you don't have marking issues inside I wouldn't spend money on a belly band. Instead, what I would do is be there when the boys are playing chase. As soon as I see Gizmo lose interest in the game and want to sniff around, I would step in and physically move Mork if he got in the way. At least that's what I would do.
