@rocky said in Only charging and biting my adult son:
All we know is the husband dropped him off saying he was allergic to him.
That sentence tells you most of what you need to know. Poor little Basenji has been given reason to fear or loathe men. Become allergic to them.
Now your son has come into his world, and he fears him. You need to build up his confidence, slowly over time. Start by getting your son to cease the games and resort to dispensing treats, being the one to give him his meals, taking Rocky for lovely walks, talking quietly and reassuringly to him all the time.
If Rocky has a favorite toy, after a week or so of no games but plenty of treats, walking and talking, get your son to sit on the floor (come down to Rock's level) play with the toy, throw it, pretend to chase it. Ignore Rocky but have obvious fun with the toy - in time, Rocky will want to join in and that is when your son, talking gently to Rocky, can start to 'share' the toy.
Main thing is to get Rocky to want to play with your son. To have enough confidence in him that he can relax and have fun with him.
This is going to take time so be patient, and be prepared to back off and put things on hold if there is a regression.
