Here's Boomer

Here's Boomer was a Heroic Pet Story series that aired very early in The Eighties, featuring the adventures of a mixed-breed dog. As The Other Wiki points out, the premise of the show was similar to The Littlest Hobo.

Newly famous on the Internet because a very big fan recently (August 2010) tried to legally change his name to "Boomer the Dog" and was denied by the court. Is there no justice?!

Tropes used:
"Like magic he appears, a hero to save the day,
 * Heroic Pet Story: The series follows the adventures of Boomer, a stray dog that traveled around helping people in trouble.
 * Keep Circulating the Tapes - in order to get an English language video of the show to put on his youtube channel, the guy had to combine video from a German TV broadcast with audio from a home cassette tape. (Picture a kid in the 80's sitting next to the TV with a tape recorder, capturing the audio) The result (http://www.youtube.com/watch?v=Ee K 8 p 0 C Bwv 8) is actually pretty good quality!
 * Walking the Earth - the theme song possibly summarizes that trope better than anything else outside of its Trope Namer:

and just when you think he's here for good,

that's when he goes away. Because he's

Boomer, he's never gonna settle down
