Mirabelle, a dressage-trained Thoroughbred mare, keeps an eye on things out in Accokeek, Md., where her owner, Michel Gauthier, stables her so he can make the quick trip across the Woodrow Wilson Bridge for a ride or to give lessons. Mirabelle, when not showing off her Level 3 Dressage skills, begs for carrots and sugar cubes. She also follows without a lead, is sensitive to the slightest change difference in position, and “speaks” both French and English.
