Hello, I hope to have some suggestions on a "job" for my pet. He is a Border Collie/Aussie mix. He is 7 mos. old and full of energy. We have 10 acres so space is not a problem. I do not have any livestock, poultry etc. We have him for his abilities for being intelligent, active, and a great all around pet. I keep reading how his kind need a "job". Can someone please help out with what type of job we can give him?? I do not expect to get any sheep for him to herd so I would love to give him something to do. Thanks in Advance.
