Silent Hound????????

i had a black and tan gyp named chigger, she was a jam up dog, and she was closed mouth till looken at a hog! i ran her with BMC and BMC/mtn cur cross! i got her as a 6 month old pup that had never seen anything other then another dog. i also had a big waker dog that was closed mouth and was run with curs from an early age. so i cant confirm it but i have had succes with closed mouth hounds that where started with curs! i currently have a jam up plott gyp that i run with curs and bred her to a nice BMC stud of my buddies, and she is also closed mouth. MAYBE im just lucky or maybe there is something to them curs that start hounds?!
