I understand that completely. But do you breed for dogs that get the job done quicker (rougher/faster) or employ methods towards that end . . . or do you just use dogs that quit and/or give up easy on tough hogs?
With the dogs I hunt with, I believe they're bred rougher/faster, which makes gang piling this sort of dog dangerous. I could vest these dogs up, run them together and probably catch a higher percentage than I do now... however, I feel hunting these dogs 1-2 at a time is safer for them in the long run though. As much time as it takes to get these dogs trained, I don't want to just throw 'em in a meat grinder to catch a couple more hogs.
I've got two full sisters(Shiner and Chub), one is genetically longer range, one is genetically short. For the short dog, it's almost like she's got an internal pedometer... she works great, but once outside 500yds, she'll disengage, return, and go right back to hunting. Now this has nothing to do with how tough the hog is, it's just that her "breaker trips" at a certain range. This really is nice when you're on small properties or don't feel like pulling out the tracking equipment... I'll also use this dog when I'm hunting around certain people... property owners tend to get real bored when I'm gone for hours tracking to a bay...a short dog like this keeps their attention, more "quick" hunts/bays to entertain newbies with short attention spans

I'm actually hoping she stays like this, opens a lot more places up to hunt.
