Travis Coates is the main protagonist of Old Yeller and its sequel, Savage Sam.
He is Jim and Katie's son and Arliss' brother. Originally, he was the first-person character in the book. Likewise, he has to be the man of the house for the summer while Jim is out selling steers for current money, as where they live used to be part of the Confederate States, but when it became part of the United States, their money turned useless. To do this, he has to take care of his family and do a man's work.
He is played by Tommy Kirk in both films.
