Oops, yep forgot to mention she already gets a wide variety of fun bones, including feet (chicken, pig, duck) and pork neck bones, ox tails, ribs, etc.
I let her work away at a bone about 3-4 times per week.
She also gets access in between to bully sticks, cow/lamb ears, pig snouts (dried), sweet potato chews, and I have been looking into getting a Himalayan chew which can be left with her full time but I am still trying to decide what size would be best for her. She's a strong chewer, so goes through "thin"/"small dog" chews too quickly, but she doesn't enjoy overly large ones either so I am working at finding a middle ground.
