What do you expect out of your dogs?

Well, if I can add my $.02, then here it goes...

I will say this first; I like to hunt a range of different dogs on the ground at one time. I don’t want all of my dogs to leave the country looking for tracks. That's not saying too many dogs either, that's just saying different kinds of "hunt". In my pack, I have two lead dogs that will find their own hog, and then some of the puppies that we will not speak of in this thread. My lead dog Fred will hunt hard making loops from 150-500 with hardly any sign on the ground, and when he hits a track he will not stop unless I'm close enough and have/need to call him out/off. My three legged dog Diablo is a short range dog that will stick semi close to you but will take a track and hunt out anywhere from 100-300 yards depending on sign. He isn't the type of dog to just go and hunt way off from you by himself, but he does hunt and take a track. Some would call him a help dog, but yet he will and has found his own hogs. Both of these dogs will honor a bay if not on their own hogs, and both of these dogs will catch with the CD; also both of these dogs, even the one with 3 legs, will put down anywhere from 15-20 miles on a hunt if in sign and on hogs. Hell, I’ve seen Fred put down 13 miles with no sign at all just trying to hunt for tracks. I like some grit, but just like what was said, I want them to be smart enough to know when to let go and back off. If I had to make it really simple, I would say that I want the dog to find hogs, be able to take to a handle and still hunt good, no aggressiveness, and not give up on a track/hog until they are about to kill over (bottom). I’d have to say that Bottom is the most important to me around where we hunt because these runners can take hours to stop in this thick crap, and even then sometimes have to call the dogs off and out.

My question is, how long do you wait for the pups on your yard to show you the specific criteria before you label them a “cull” from your yard?
