I use food, tiny pieces to train Hap. It has worked well for us. At first every time he got the treat fast, then sometimes not, and sometimes a lot at once, like a jackpot. He still gets treats, but we can go days with none, then one, and then he will hit another jackpot.

I don't think I'd work if I didn't get a treat at the end of the week.
