Active, intelligent and very much a farmer's dream dog by the sounds of it. My brother in-law works on a farm and they work collies and every so often a few Aussie's but he has said if the oppertunity presented itself he would have one. Dont lack in confidence and live for their work. It could be a Kelpie cross but without a picture couldn't even hazzard a guess. Usually its those ears that give it away (look like they pick up their own radio frequency) nice sounding dogs though Iv never had the pleasure of meeting one myself.
Pretty much like any collie or working breed, keep him busy doing
