Anyone out there ever used a black mouthed cur breed for cattle work? Wondered if they were supposed to be good, an all around kind of dog...like Old Yeller? That dog was supposed to be a BMC, but who knows? Anyways, curious! We are looking for a dog or mix of breeds other than aus. shepherd and border collie, need something that will move cattle, heel a bit, not back down, and can also protect our ranch from wolves if they come around again!
