I have been buying partial cows butchered for my beef for about a year now. I get great meet that is grass fed and no hormones from a local farmer I know and trust and save money in the process. With all my cuts of meet, I also get a few packages of "soup bones". We have never done anything with these bones as we don't really have a desire to make broth from scratch for soup. Would these bones be OK to give to our dog, and if so at what age? (she is 5 months now).
