Looks like Plott and Mt. Cur mixed. There's an actual registry and program for them through UKC and national breed club, so its not entirely just a mixed up mutt. They usually have a high prey drive, least the ones I've met and couple I've played sitter for for friends. They are usually a more orange wider spaced brindle (or orange/black masked marked) and are good family dogs. They coloring on that one is more like a Plott's if it would be lightened up a bit. My sister raised Plotts for a couple years, they were big goof balls 99.9% of the time but when they were out hunting it was all business to find that coon. Mt. Curs have a bad tendency to chase chickens and cats though if not properly trained early on and they can be VERY stubborn to break from bad habits. One I sat I was told had a head of time that he would, if not leashed, take of on any scent even if it was days old to try to find a coon. While might be good for a hunter, its not good for an unknowing (and not counting on a 5 mile or more hike) person. He said he's tried to break him from running constantly like that, but never has. He's just got high drive and when out he's a darn good dog, too good to make him into a lazy house dog or even try to deep down. Mt. Curs aren't a big dog, but not a small dog either usually 35-45lbs but I have seen some big ones on hunts tipping scale at 50 and 60 lbs or slightly more. They are really common on coon hunts here, have had more than one wonder in. They are usually friendly, never had one snap or act aggressive towards me like the coon dogs that often come in with them. She looks like she'd make a good dog for you though
Happy and friendly, plus if any pesky raccoons are around....no more garbage pick up or at least if she has any hunting blood in her...
Taken snip from UKC formal breed history:
"The Mountain Cur was declared a breed in 1957 with the organization of the Original Mountain Cur Breeders of America (O.M.C.B.A). Prior to that time, dogs of this type could only be found in very remote, rural areas and there were no organized breeding records. The most common strains of Mountain Cur included the McConnell, Stephens, Ledbetter, Arline and York strains. OMCBA was able to assemble breeders and register the original-type Mountain Cur. On the last weekend of September, 1991, a group of men and women met at Robert and Lou Ella Kemmer's house and formed a new breed club that registered a strain of line-bred cur that became known as the Kemmer Stock Mountain Cur. These curs are Mountain Curs that are bred from the above-mentioned lines. The best was bred to the best and then line bred. Kemmer Stock Mountain Curs were first registered with the Kemmer Stock Mountain Cur Breeders' Association (K.S.B.A). Mountain Curs from O.M.B.C.A. and K.S.B.A. provided the foundation stock for the U.K.C. Mountain Cur breed. Today these dogs are used on squirrel, raccoon, and all types of big game.
The Mountain Cur was recognized by U.K.C. on November 1, 1998. "
