You are asking about the size or circumference of the pastern and stifle, the area between the foot and the dew claw I think. I have no idea but if I remember I will measure them tonight when I bring them all in. Think they are called the metacarpus and metatarsus bones in the dogs. Don't think dogs have ankles and wrists. That might not go over real big with your teacher if he/she knows anything about animals.
