Cudaspaz -
Years ago we had an Irish Setter that was as gentle as he could be, but our neighbors had a teacup poodle that was extremely belligerent. He came tearing after our Setter one day yapping for all he was worth. Our Setter just stood there while this little ball of piss and vinegar kept yapping at him.
Finally after at least a full minute, our Setter reached down, picked up the poodle and shook it just one time, set it down and it ran off for 'mama' yelping all the way. Neighbors were just like Betty, glad another dog finally taught their little terror a lesson.
That little poodle never left their property again whenever our Setter was out in the yard.
It was hilarious.
