All work and no play

Makes Sam a dull boy.

Sam would have you think that the life of a guardian dog is all work and no play. It's guard, guard, guard - 24/7.

However, if you're REALLY stealthy...

and use your zoom

you can catch this

and this

and this. But if he catches on to  you...

you get this.

The sheep have checked out the object of his affection.

but so far

just don't get it.
