Recently I read this magazine and one of the cool tricks was to teach your dog to close something. First find something light weight that your dog can close easily. (If you have a small dog do this on a lower cabinet, if you have a big dog do it with a bed room door)Open the door or cabinet that you're using, apply a little bit of peanut butter about 5 inches above your dog. Show your dog the peanut butter and he'll have to jump up to lick the peanut butter. His or her paws' will press up againt the door or cabinet and it will close.
I hope this trick works and you and your dog enjoy it.
