Agreed. Well put. I agree there is a correlation between structure and performance. I just always have put mouth on a shelf by itself. That long and lean dog is normally and can be expected to be faster than his short/stocky/muscled counter part. That stocky/muscled dog can be expected to be stronger. That long dog can off set the strength with leverage. I see the correlation between the that type of structure and performance.

Either of these dogs can bite and either can not. Same with the heads. The jughead dog might crush shit but his twin brother can not. There is no real explanation. That is why I said there is no correlation between the two. I agree it should be, and in other areas it can be and has correlation. Mouth is like a different animal altogether. EWO
