Milo has never walked away from a bone! Lol. But I also give him appropriate portion. He could probably eat an entire chicken leg but he gets a skinless drumstick instead. Duck feet, pork rib tips, chicken back, chicken wings, turkey wings. I don’t give beef bones, but when I have some game meat, I do get milo to chomp on the part where there is a ton of sinew, so it acts like floss for his teeth but not on the bone itself.
