When a horse has cow sense, he is said to be “cowy.” Basically, this means he has an instinct to anticipate and react to a cow's moves, and is smart enough to go after the animal that his rider points him toward.
Boss is “cowy.” He doesn’t like sheep and is terrified of goats (and bears), but he really likes chasing cows.
A lot of the public lands we ride on are used for cattle grazing. Sometimes the animals scatter as we ride past, and Steve and Boss take the liberty of rounding them up just a little.
I would have better pictures if my quad-pod (Mischief) would stand still for my photo shoots!
