Great thread.
Now the question.
What are y'all's opinion on too tight? Wait until something shows up, or a specific number of generations? I read earlier that some lines handle it better than other. I am just trying to learn from you guys that have seen it and done it. Right now, I am on a 5th generation, no out cross at all.
I saw smaller testicles and smaller litters...5 or 6 pups...towards the end some of the pups hunted a little too hard...there were three that died from heat exhaustion...my belief was too much hunt and not quitting as long as there were hogs to run...or maybe it had something to do with genetics...or a combination of both...

My dogs started out with plenty of hunt and seems I got a little extra grit with a few and lots more hunt with some as well...but I was selecting for that...
