Here's a rattlesnake. The only time a game dog is going to be any different to another dog is going to be if its getting wailed upon by another dog. Who needs that in a dog unless thats why they have it? People want some gamebred thing thinking its going to be the holy grail but unless you are throwing them in the situation to prove their gameness, which can only be truely proven in combat, you will never have anything better than the next guy down the road.
