We raise registered australian shepherds, they go back to hangin' tree blue bear and are a foundation line that stay short to medium haired. Best part about them is they pretty much train themselves are are cowy as all get out! My pups want to start working at 6 mos and will keep a stranger away from the vehicle at that age too! My female rounded up 100 cow/calf pairs and swam them across the niobrara river by herself when she was about 2 yrs old. My male dog worked cattle aggressively at 9 mos of age when my husbad was working for O'neil Cattle Company AI'ing cows and heifers. Fortunately I have been able to breed them to be a "direction you are going dog" so when the cow turns on you the dog doesn't keep following the heels and chase her over the top of you, he bites her nose and turns her around and keeps her going! We also love to have ranchers that enjoy using dogs have our dogs, if you know someone looking, send them a line on us!! Our dogs were also at the Black Hills Stock Show at the petting zoo, so if you were there, you saw em
