Me and my boyfriend have had our Alex Bozo for about a year. He's about 21 years old. The problem that I've been having with him is he hates my hands. He won't let me pet him or anything. The funny thing is he has no problem with my boyfriends hands. The only way Bozo will let me pet him is if my boyfriend is petting him too. Bozo has no problem coming up onto my shoulder or giving me kisses but the minute my hand goes near him he gets nervous and tries to bite me. What do I do?
