You are not a failure at all! Knock that nonsense off!
Gimoz when he was little liked to pee on bathroom rugs, so I just started closing all the bathroom doors. Is it possible to confine Mr. Peanut's access of the house until he can be trusted a little bit more?
What about belly bands? Those actually helped us with potty training because Gizmo hated them being on and hated the feeling if he wet in it.
