Dog and Orangutan's Friendship

Those are actually really good ideas/solutions for the orangutan, Victor! I think introducing another dog, a young one, would be ideal at this point since he may be a bit too young for having a mate right now. I've no idea when they become sexually active though, but since he seems happy to hang out with a dog, it would be good to get him another canine buddy to become focused on and involved with before his old friend dies.
