Been thinking about his a lot lately. What are your thoughts?
A sprinter is typically longer than the average joe from the ankle to kneed and elbow to wrist and his waist is a bit higher than the common fellow of the same height.
A man with shorter arms can bench press a man of the same weight who has longer arms.
A thicker man can squat more wt than a skinny man of the same weight.

These are examples. OUTSIDE THE FREAKS AND EXCEPTIONS, what are your thoughts on the shape of the dog's head and his ability to bite? Not something I'm extremely focused on, but it's something I've been thinking about. A longer legged dog typically wrestles better than a short legged dog.

Head structure does play a role in the ability to bite or how hard. Is this something you guys consider?

I know there are a 100 other variables to consider, but when selecting stock to breed and many things being equal, what are your thoughts on head structure?
