I buy them, and my boys LOVE them! I get the chicken and beef liver ones. Those are the "special" treats. They only get them when we have to leave. I'll grab the bag and tell them we have to go to work (we can't say bye bye, because they know that means they get to come too
), and they will both run and get in their beds (in their pens). I've never tried the cheese ones though. They also work great if you have a picky eater. I've taken one and crushed it up to put on their food, and the liver has more of a smell, so it gets them to eat too.
