How is lennie's treatment of his dead puppy typical of his character?

We must consider Lennie's primary motivation through the book: the chance to "tend the rabbits. Everything Lennie does revolves around petting soft things. Weather it is a mouse, a puppy, or the hair of a woman: Lennie wants to pet it. Unfortunately Lennie has the emotional and intellectual maturity of a six-year old inside the body of a big man. Any petting session he has with anything ends badly. He invariably pets way too hard and kills the object of his affections.
