So I have two.... (Yes I'm crazy) lab pups. A silver named Turkey, andaChocolate named Choco. We have been working on manners. I snap my fingers and use a finger pointed upward for sit. They got that pretty well no treats for that but i did use shunning. Where I turned away when they did not comply. As for manners they now will sit so nicely when they see me grab their dishes to feed them. They wait till I give the command "ok" to approach their bowls. They do not try to eat or take my food usually. These pups do not always get it right. But I say they are pups. They will eventually.
