I just wanted to respond to this thread. I hope everything is going good with you and things are working out. The thing I wanted to respond to was the thought that a man may have abused him since he does not do well with men. A basenji can make their mind up about disliking something for no reason at all. My first Basenji was with me from 6 weeks of age and never had a man abuse him and at two years old decided he hated men for the next two years. I kept him socialized and kept getting men to feed him pet him while I had him stacked and holding his head, had them talk to him, go over hime etc. after a while his dislike left as quickily as it came. I have had a few dogs do this sort of stuff between 12 and 18 months I call it the stupid stage, they all the sudden don't like men, women, the grooming table, the trash can outside etc. It is important to work them through their fear so they can be a complete dog. Just think how it would be for you if say you were scared of men but had to see them daily just think how stressful your life would be. I hope if you keep him you help him get through this or if you place him please be honest with the new owners and recommend that they get him out and work him through this.
