Biting Other People

My Baby Bubba

My Jack Russell's name is Bubba and he just turned 2 in January. He has bitten at least 4-5 people since we have had him. He recently bit my moms friend on the back of the knee. It is random people that he bites, mostly strangers. I don't know what to do about the biting. It has come to the point where I can't take him anywhere or let anyone in the house because he will bite them. I brought him to training but it didn't work. He barks all the time at other people and dogs and I'm at the point where I cry. I dont know what to do. Does anyone know what to do?
