Wondering out loud.

I have started many hounds by themselves that have opened on track without ever having been shown by an older dog. Its in their blood, and what they were bred to do. But doesn't mean they all will.
       Same as curs being silent. Starting a pup of any breed too young, alot of times will cause them to babble out of frustration and/or excitement because they cant keep up with the big dogs. Some grow out of it some dont.
    Alot of it depends on the individual dog. I have seen a couple open mouthed dogs "learn" to run silent too.
good luck with your pups

Bingo...

I mixed the four best plott lines I could find when I crossed these dogs, I blended fox/cat dogs for thier intelligence, cold trailing abilities and I mixed hog and bear dogs for grit, and desire as well as the ability to shut up on a track until they see it... I believe that this has produced a really good mix of genes to catch a variety of game on different terrains. Well the genes are their, I think it takes environmental element to get the gene expressed such as running open with open and tight mouthed with tight mouthed dogs especially in a breed like the plotts that are used for hunting different types of game that have different requirements.
