Bow-Wow-Wow

Bow-wow-wow!

It's the great watch dog.

I know by his honest bark,

Bow-wow-wow!

Says the great watch dog,

When he hears a foot in the dark.

Not a breath can stir

But he's up with a whir

And a big bow-wow gives he,

And with tail on end,

He'll the house defend

Far better than lock or key.

— Scotch Nursery Rhyme
