I just keep going back to that ol saying you get out of something what you put in, so when it stops on you and your the kinda guy that has no love for it then you really have to figure whether or not you did everything in your power to give said dog the best chance at being successful.
Then again I spend more one on one time with mine so I love more things about them than performance. With that said I know what these dogs were bred to do so I keep that in full perspective. But at the same time if this fucker is dumb, or not a pleasure to be around and the ONLY thing it can do is brawl, that's not my ideal dog I like em well rounded from the attitude to the conformation to intelligence to producing. Reason being is because a dog may win/lose because of the situation and not its own ability. Some are miss matched, some aren't ripe, some are stale, and many many of em have idiots for owners that kill the dogs potential and credit but it all falls back on the dog not the guy who instead of love he puts nothing but expectation on the dogs shoulders. There's nothing wrong with loving your dog just so long as it doesn't blind you to the truth.
