Meursault describes his meeting with Salamano and his old dog. What is Salamano's relationship with his dog? How does that relationship contrast with the way Meursault lives his life?

Salamano and his dog have a love/ hate relationship. They are inseparable, but they also fight constantly. Salamano is abusive, and his dog responds violently. Meursault is very much unable to feel love or hate.... he feels nothing.
