Don't know about the other big dogs out there...but mine aren't going to let me sit still.
Chance got in a great chase across our back yard with a squirrel this morning. Whoosh. From one end to the other -- dumb squirrel was on the ground in our yard, not on the fence!
Squirrel made it through the bottom of the fence in time, glad to say. Then a train went by down on the water -- and Chance proceeded to answer it's horn with a hound-dog howl. What a riot! He'd have made a Coon Hound jealous. Matched the train horn perfectly.
