I was out the other night, and someone played this song that was an absolute unabashed tear-jerker. It was about a couple of kids who'd decided to drown their dog because she was too old. The chorus had something about the look in the dog's eyes saying "I know you'll always be my friend." The final verse (before the chorus) has the older boy falling into the river as they're about to chain her up and throw her in, and the younger boy is too small to save him, so Dixie dives in and pulls him out. All I remember about the author is that his last name was Sykes, which doesn't really narrow things down. Anyone know what I'm talking about?
