Goose,
I like the right mtn curs better than any other breed I have hunted. They are somewhere in the middle between bmc, cat and plott, walker hound. They also have that long range winding ability. The mtn curs that Charles Fasola has should be cold nosed and long range winding type dogs. These dogs will circle around you 3 to 4 hundred yards and will go deeper if you don't move but will keep circling around you if you are traveling on a 4 wheeler. If they take a track they will leave out on it and go untill the hog is bayed.
If you don't like open mouthed dogs then find another breed or look hard for a silent mtn cur.
Most will not open on a cold track but will open some on a smoking hot track or open some once the hog breaks bay. These dogs have been bred to hunt for many years.
Just like any breed you will have culls but if bred right that should be minimal. The biggest thing is finding a breeder that breeds the type of dogs you like.
Charles Fasola has pups from time to time and Marshall Willey has pups now that are grandsired by Charles best stud dog named Duke. Also a man named Rob Day keeps some cold nosed dogs. As soon as my gyps coe in heat I will breed them to some good hog dogs out of my old line of dogs. These gyps are out of Marshalls dogs.
There is one large original mtn cur around your area that I am really interested in that I would like to get a pup out of. He is a world champion squirrel dog. I have seen squirrel dogs make awesome hog dogs if they have the right equipment. I will post a pic of him up now that I know how.
Most mtn curs quiet down on the track when they get about 2 yrs old and also if you hunt them regular. They tend to be gritty and catchy.
