About the only thing Buck and Yella have in common is their color

In my mind Buck is a strike dog and Yella is a catch dog...
You can cut Buck loose from the truck, let him take a track, then go hunting your other dogs. Come back to Buck in a couple hours and see what he has worked out. He might still be on the trail, or he might be looking at the hog. Only time I have ever seen him check in was after him starting a track in some palmettos at 7:00am, and he started working his way back near 11:00am. Every other time we have tracked to him. With the exception of one other hunt. We had several inches of rain on a Friday evening, went hunting Saturday am, we never saw any sign, and he never went out past a couple hundred yards. That one hunt got me to thinking that maybe he is not so long ranged, as he is cold nosed. Give him a track and he will take it for hours...If there is not a track, he won't go far looking for one to take... I would not call Buck rough or catchy, he will catch when help is there, but I have only seen him catch a 50# pig on his own. Buck weighs 68# on the vets scale. To me Bucks primary faults are that if he is on a big hog he will walk with it, rather than turn it, and he seems to work a track a slower than some other dogs I have seen. He does not burn up the woods, just slow and steady. Buck is certainly not a super dog, but he's far from being a cull.
Yella is going to hunt short range, and pretty much catch what he finds. He has been used as a lead in catch dog, and also as a RCD, however he will do a little hunting on his own. His current owner Ray has mentioned that a time or two he has gone out with the other dogs several hundred yards, and a couple times he has bayed a bit before catching. I guess there are no absolutes, but I still think of him as a catch dog more than a strike dog. Pretty sure Yella is going to weigh about 5-10# more than Buck, though I never had him on a scale.
