Taela Lae, sweet little Sheltie girl
You're gonna be missed on this sad old world
Your chipper self, always alert
Saved your people's lives, kept them from hurt
But hurt now they do, dear,
  from saying good-bye
But you bark once in their dreams tonight,
  so they'll know you're nearby
Watch over them, ever faithful,
As you always did do
And someday, at the Rainbow Bridge
They'll reunite with you.

Woof!
