This is the first summer our horses have worn fly masks. Well, at least SOME of them have! Cali, of course, was very calm about the whole thing..."ho hum". She could have cared less. She just wanted some attention! Gigondas, who had a THING about people touching her head and ears, accepted hers with the quiet dignity that she now has and didn't even put up a fuss. She rather enjoys hers! And, Scout, the "wild one" calmly accepted one when I offered it to her. That's quite a bit of trust from a mustang! And, of course, Quad readily accepted his. He's a pro at this kind of stuff. I actually take his off every now and then. I haven't put one on Sunni...too much "drama". I notice that some of our horses need them...not the mustangs, but the thoroughbreds and Sunni, the quarter horse, and Lady, the grulla. And, it doesn't seem to be their color. Both mustangs and Quad are light colors, while Sunni and Gigondas are darker. Any ideas or thoughts about why some horses need fly masks and others don't? I do add some apple cider vinegar to their water. ABC Wednesday for August 26, 2009.
