I use them. My girl loves them. They are a little big for training if left whole. I cut them into quarters for training treats. They break into small pieces easy enough, too, but I do find they crumble a lot if you break them with your fingers. I use them mostly in her treat puzzle and kong. I have used them for training but prefer to use Wellness bites. I cut those, too.
