I FOUND MY BEST FRIEND IN THE DOG POUND
As recorded by Jesse Lee Jones on the various-artists collection "Doggone Country: Favorite Songs about Dogs" (2008)

I found my best friend in the dog pound,
The best friend that I ever had.
When other friends failed me, my pal with the tail,
He still came to see me when I was in jail.
I found my best friend in the dog pound.
He's an old pris'ner like me,
Who'll always be grateful, when the dog catcher caught him,
That I set him free.

I found my best friend in the dog pound.
He's an old pris'ner like me,
Who'll always be grateful, when a dog catcher caught him,
That I set him free.

For one measly dollar,
A tag for his collar,
I set him free.
I set him free.
Oh, I set him free.
