My dad is a deer hunter and took a nice buck on Saturday. He was cleaning the deer yesterday and saved me a big pile of scrap meat and a large shoulder bone for Gunner. I'm freezing it for a few weeks to kill off any parasites. I plan on giving him pieces of the meat for training, and the shoulder for a large teething treat outside. Anything I should be worried about or anything else I should do to make it safe for him?
