Dave,
I'd guess your running young patch dogs together, what else would you expect?
3X's solo, 1X pack. If you got some older hounds, mix the pups in 1 at a time till they mature and settle...you got to break the motor in right, not drive it like you stole it from the start...

If you want a more mellow hound but yet in the patch blood, get you some Yates breeding, they were bred to hunt and for the spo trials down south, they come with more of a governor on the motor from the start but grow old quicker.imho
At 3 years old you pretty well see what you got in either type. A blending of the two has proved to make a well rounded hound. Each breeder seems to add heavier on one than the other according to their likes and dislikes.
That's the thing with looking at finished running hounds when picking pups, you don't know how they developed and what it took to get them there. If the breeder would tell you what to expect as the puppies develop and how you should go about avoiding problems, I think people would not become disgusted or give up hope too soon.
Best of luck with your pups.
