Cracker is ONE happy dog! The butcher at my Publix kindly made me a custom package of marrow bones of 4.5 pounds vs. the usual tiny ones, then charged me just $1.29 a pound vs. $1.89!!! I boiled them in salted water, drained then froze them in a bag in my fridge's freezer. I used to microwave them for him until recently upon realizing JUST how much he loves to eat ice cubes....I now give him the bones right from the freezer....dog paradise for my best little buddy!
