Size can depend upon the bloodline, nutrition, and environment.
The DACA standard does not have a top on the height at present. We do not want undersize Dogos for the same reason. Smaller Dogos under minimum height will not have the length of leg to cover ground chasing a boar or mountain lion. If he gets to the quarry he will not have the strength to hold it until the hunter arrives. All other points being equal, the taller, heavier Dogo is to be preferred, provided he is balanced and in condition.
