Who's a Good Boy? is the bronze trophy for petting Buckley, the dog at Tommy's hydroelectric dam in Jackson County. He is part of the work party at the dam, and Tommy jokes that he makes a poor guard dog.
When you reach the dam with Tommy, find Buckley outside the generator building and use the prompt to pet him.
