other songs that I wanted to find for this show were:

Mr. Bojangles,
Uncle Charlie and his dog Teddy, Nitty Gritty Dirt Band
Shep,(by Ramblin; Jack Elliot)
a bluegrass song about a dog that came to church
after his master was buried in the churchyard,
Greg Brown's "Like a Dog"
Utah Phillips has a song about a dog by a train yard
Gotta stop kickin' my dog around...

got any others?

the theme song to Lassie t.v. show...whistled...I can hear it now..
and perhaps music from any of Disney's doggie flix
Grey friars' Bobby,
Old yeller,
