repetition. When our dog was a puppy we were decorating a common area tree with a neighbor. I told her to lay down while we worked. She would get up and come to us. I would bring her back and tell her to lay down. she would get up. I would bring her back. I was doing that about as much as I was decorating. My neighbor was like. Forget it Ill hire someone. Guess what though. The person who you hire has to train you.
