I have seen a pair of shepherds tree a chuck 25' up to the top of a maple sapling, just swaying back and forth.
Farmer who rented the field across the road growing up had a black lab that would sit by a hole for hours waiting for them to pop their head up.
We had an old farm collie/shepherd cross who was gentle as could be, she loved to just follow the scent trail paths through the tall grass, rabbit, woodchucks, whatever. One day we watched her following one of these paths and there was the WC, who took great exception to the proximity of her nose, and nipped it. So she caught it in the middle, gave it a shake, no more woodchuck. She was a little hurt and mostly happy, and Dad was happy too.
Dad's property was all river clay/reclaimed swamp, and there were several drainage ditches across it. Every 10 years or so the town would come out and clean out the silt muck and grass. Woodchuck holes along the ditches would make the sides slump down into the ditch, making it harder to mow (with a riding mower or cutterbar on the AC-B) so Dad was always bombing chuck holes and filling them in.
But even more unforgivable was the war over green beans. Dad would have either the beanpatch or the whole garden fenced, everything going along great, beans flowering and young beans ready to pick and overnight, there'd be a hole dug under the fence and the whole bean patch would be down to nothing but stubble and there'd be a nice new den dug smack in the middle. Dad took to spending the evenings watching the beanpatch with a scoped pellet rifle. He had a .22 but it would wake the neighbors.
