How hard is it to break a dog from digging? Boomer has turned into quite the excavator now. He does it in a matter of minutes. And we're talking HUGE holes all over my yard now. I want him to learn that he can't do that and haven't got a clue how to teach him that other than catching him in the act and saying "no" which so far has had absolutely no effect on him. He will look over at you and continue digging. Can anyone give me any tips on what to do to remedy this problem?
