The dog's footpad is a fatty tissue locomotive-supporting organ, present at the bottom of the four legs, consisting of digital pads, a metacarpal pad, and a carpal pad, with dewclaw near the footpad. [26] When a dog's footpad is exposed to the cold, heat loss is prevented by an adaptation of the blood system that recirculates heat back into the ...

In humans and elephants, a vertical-column orientation of the bones in the limbs and feet is also evident for associated skeletal muscle-tendon units. [ 6 ]
