My service dog, Romeo, is a picky eater with a sensitive tummy. I got the green-lipped mussels on a whim but was 90% sure he wouldn't eat them. He LOVES them! They're easy to feed and good for him. As for the beef liver sprinkles, I can't imagine life without them. My formerly picky eater will eat *anything* if I put the beef liver sprinkles on top of it first. And a little goes a long way, so these are very cost effective. I LOVE everything we got in this box!
