I do that, too! It seems to work at the door for about a moment, but then later Sug surges forward to about 5 inches past my left knee. I think I need the Ilusion collar. He is a stubborn muttley.
Sug likes to watch the shows, too. He likes the pits when they move around on the TV, he jumps up to smell the TV and goes around the back of it, too. Poor guy. I am convinced that he will ecognize that man's voice.
