I'm in love with a 120 lb 30in Anatolian Shepherd

Okay. Maybe not those measurements exactly. I'm in love with this dog. I really, really want to help him, but we're not in a good place to do that, and I can't take any more dogs. Not to mention, my Mom would have a cow because of his huge size. He is apparently starving himself because he is so depressed. His owner left him on the side of the road because he didn't get along with her cat, I guess. I really, really, really wish I could bring him home with me. =(
