Enzo likes to dash in and out of places. I asked him for a sit and wait while I open the door and step outside. When he got up I calmly put him back. I don’t repeat the command, I just disagree with his action and say “Eh,eh”. I put him back in a sit at the original spot. He is smart and easily handled this exercise! Even with all my standing by “helpers” saying “go for it!”
