OLD YELLER is a touching tale. The scene when Jim returns, as Travis and his friend Lisbeth are burying Old Yeller, is particularly meaningful. Jim tells him that the loss of Yeller is "not a thing you can forget. Maybe not a thing you want to forget. ... Now and then, for no good reason a man can figure out, life will just haul off and knock him flat. … I'll tell you a trick that's sometimes a big help. Start looking around for something good to take the place of the bad."
Jim's talk with Travis is a model of parental wisdom, understanding, and patience. He accepts and validates Travis' feelings completely, and does not try to minimize or talk him out of them. (Contrast that with Lisbeth, who tries to comfort Travis by encouraging him to "come to like the pup.") Instead of telling him what to do, he says, "I'll tell you a trick that's sometimes a big help," letting him decide for himself whether to take the advice. Travis was not just reluctant to adopt Old Yeller at first -- he was downright hostile because of the loss of his first dog, Belle. That, at the end of the movie, he is able to accept Young Yeller more easily shows how much he has grown up.
