Some of our neighbors put a great deal of effort into training herding dogs, and when it turns out a dog just doesn't have the knack, it's a fairly substantial loss of money, time, etc. In fact, Saturday we witnessed the fun that ensues when a (small) flock of sheep escapes and runs around town. The ram and his three or four young ewe companions had quite a time of it while various locals on ATVs, dirt bikes, and whatever else they had at hand tried to corral them again. One neighbor tells me he'd rather drive 10 miles to fetch a sheep dog than try rounding up a flock on foot. That said, I wonder idly if this is a suitable alternative... and how it would fare against the somewhat more scrubby terrain some of the local ranchers have to deal with.
