Our work was done then; the cattle had to walk on like sheep in a race.

We led our horses behind them, and the dog walked along, saving his sore feet as well as he could, and never tried to bite a beast once he got within the walls.

He looked quite satisfied, and kept chuckling almost to himself.

I really believe I've seen dogs laugh.

Once upon a time I've read of they'd have taken poor Crib for a familiar spirit, and hanged or burnt him.
