FIDO'S FOOT is a term used to describe the PAW of a dog. It is made up of three letters, PAW, which stands for the Pad, Astragalus, and Wrist bones. The Pad is the fleshy part of the PAW that provides cushioning and protection from the ground. The Astragalus is the bone that connects the PAW to the leg and helps with balance and movement. The Wrist bones are the small bones that connect the PAW to the leg and help with stability and movement. Together, these three bones make up FIDO'S FOOT, which is essential for a dog's mobility and comfort.
