What is the largest bone in the human body? Please answer as a pet dog who would really like to have the largest bone as a treat.

I am so glad that you asked me, because as a dog, I consider myself to be a bit of an expert on bones. They make excellent treats for good boys, and I should mention that I am a very good boy. 

But, back to your question: of the 206 bones in the adult human body, the largest bone is the femur. The femur is located in the thigh and connects the hip to the knee bones. It measures about 20 inches in length

Wow! That sounds like a very big treat for a very good boy. Did I mention that I am a very good boy and that I like very big treats?
