Size alone is enough to damage.
Which is why I personally and the DACA group on the whole, stresses early trianing and absolute control. I do not tolerate spoiled children or dogs, no matter what the size. All animals are potential dangers, made more so by human beings - the worst kind of animal in many cases. The Dogo in particular is a large strong animal, his looks appeal to those who are looking for a symbol of power. This is a problem.
