I tried never to reprimand my dogs with force or loud yelling. Every time they misbehave or do anything that they specifically know that I do not like (intentionally and not in a playing mode), I restrict their freedom by placing them in their cage for fifteen or twenty minutes. It took about 3 months for them to realize that every time they do something that I do not want them too, they will get stuck in the cage for a while.

Try it if you like. Either that or buy two socks every time you buy a new phone sock.
