Oh my God, the poor thing, I would take him in a heartbeat if I were closer! I have more time available than you do, only problem is we just got rid of a roommate and her chi mix dog who marked all over the apartment... we JUST got the carpets cleaned and the smell gone (as well as the nasty roommate) so.. I just... man. He is so beautiful, and I hate to see Aussies up for adoption and not able to take them in myself. I just want to say, you do what you think is best for both you AND him and the situation at hand. Don't feel bad about the decision!
