We are so lucky to have a butcher near us that allows us to take the remains after they process animals. I have a freezer full of beef carcass and the dogs are loving it. We have ribs, hip bones, femurs, tendons etc. I put the dogs out in the backyard with enough bones for everyone. No one had a problem and each one found their own bone. Even Trouble (12 weeks old) found his bone and settled in by himself. Trouble goes to his new home next week.
Here are some pictures of the dogs going to town on their treat.
