My husky did something similiar the day I met him. He wouldn't let me pet him. So I tried something similiar to the treat thing mentioned above. I sat down with my shoulder to him and my head down then I held a milk bone out in front of me. After about 10 or 15 minutes, maybe longer, he finally came up to me and let me feed him and pet him. I was outside so tossing treats wouldn't really work (the barn cats would have stole them). After that, he wouldn't return to his previous owner..he was and still is glued to my hip.
