Game Dog 

1.A Pit Bull that has what it takes to not only fight but win.
2.Any hunting dog that is willing to risk life to hunt hold/kill a large or small animal even if it is much larger then himself.

That dog went off the chain 3x and blew thru all 3 dogs it went up with that's a game dog you got there.

The Hot Dog Game 

The game your uncle plays with you when your family isn't looking on family vacation. Results in years of therapy and emotional stunting

Uncle: Hey sport! Wanna play the hot dog game with your uncle Jimmy?
You: Uh, what's the hot dog game?
Uncle: Well, you show me your hot dog, and I'll show you mine, and whoever has the biggest hot dog gets to stick it in the bun!

You: Uh I guess so

That dog that no matter how badly injured it is, will give its life to perform whatever task it's focused on; especially fighting or hunting.

I once went as volunteer to a dog fighting show bust and rescued a two time winner Bullyson doggy that I could see him proving to be a complete gamedog; he did the courtesy scratch with a broken leg and as soon as he reached the other dog we began to enclose these despicable idiots in their own building, arrested them and seized their bulldogs.
