to put a k9 training collar on a 23 year old? I have the pleasure of my nephews company when ever his girlfriend throws him out. My nephew grew up in a home where cocktail hour started very early. He is missing some of the social graces kids are taught. I have tryed everything to get the boy to wipe his feet before entering the house. You would think that would be a very easy thing to teach someone. I am at my wits end. I have tryed calm talking, screaming, I dragged him to bed bath and beyond,made him spend $80 on a new door mat. Once I waited till 2am, rolled him out of bed and made him wash the kitchen floor. I came home last night to muddy footprints all over the floor. Think shock therapy might work?
