I found when Wolfie misbehaves, that time out in his crate works wonders. I leave him in there for a few minutes and he comes out calm and ready to be a good boy. I don't say bad boy or anything like that when I put him in ther. They say you aren't supposed to use the crate as punishment. When I started doing this, I would just take him by the collar and say time out, and put him in the crate. It progressed quickly to me just saying time out and he would go in his crate. Now, just like a little kid, he will do something bad, and go right into time out without me saying anything. So, maybe this isn't an effective tool anymore. He does something wrong and punishes himself. Is he learning not to do that behavior or is he learning the behavior is acceptable as long as he goes in time out?
