ghost of a dog - brickell edie and new bohemians lyrics

how can that dog be barkin’ in the backyard?
we ran over him years ago
how can that dog be runnin’ by the backfence?
we ran over him years ago
ghost of a dog
barkin’ in the backyard
how can that dog be scratchin’ at the back door?
we ran over him years ago
how can that dog be lying under the shady tree
where we buried him years ago?
ghost of a dog
flyin’ through the backyard
