"Fobby doesn't do fly spray." Bruce told me."Not yet." I replied.We filled a spray bottle with water and began. I had Bruce walk up to the colt and begin spraying his lower legs, the sprayer in one hand, and the lead rope in the other. Of course Fobby jumped, and bucked, and snorted, trying to get away. Because Fobby knew to keep the rope slack, and to honor Bruce's personal space, he didn't drag or pull. He just did some incredibly acrobatic maneuvers trying to stay out of spray range.I had Bruce keep spraying until Fobby paused, and then he'd quit. After a short breather Bruce would start again. It took awhile, but two bottles of water later, Bruce got the fly spray on, while Fobby stood quietly.Bruce was really tired, so we didn't start to longe until the next week. Fobby was fine.
