Went through a stage where he would only eat out of my hand if we were playing tug/flirt pole, if we weren't playing that he wasn't interested lol. I've tried when we were out and about but he'd sniff it then turn his head away.
He's a strange one, seems like the more I do to get him on board the more he resists and the less I do the more he wants to be part of the team, so to speak.
