When I was growing up in Texas, it seemed that most of the horses I was around had spent some time in their life pastured with cattle. Pastures were extremely large and it was kind of expected that they would have cattle and some horses as well. And many people turned mares and their older foals out to let the young horses grow until time to learn saddling. So, most horses didn’t give cattle a second glance.
Fast forward to recent times. There is a lovely small ranch? farm? in North Texas with a nice cross-country schooling course built on the forward part of the cow pasture. If you are going there on open schooling days, you and your horses will share space with the cows, as there is only the perimeter fence, and no fence to keep the cows off the cross-country course. The owners see no reason why that would be needed.
Cows being cows, they tend to gather near the cross-country area to stare fascinated at the horses jumping obstacles. What on earth has got in to those horses to make them gallop and jump like that?
Of course today the horses may come from anywhere. Maybe they’ve seen cows before, maybe they were unaware that there was such a thing.
The rider on the bravest horse can ride toward a group of cows and kind of shoo them back a bit. The cows do seem to get the idea that the bleacher seats are best for watching the show.
