Dog agility ... and she's really good at it. She and her Border Collie, Jackson, have been competing for a long time (he just turned 9) and they have qualified for Nationals two or three times. Jackson is perfection in motion when he and my sister are running a course.
Three-year-old Roxanne (Sheltie) is coming up the ranks, and she is a bit more opinionated than her brother. In this video I shot of Roxanne running the course yesterday morning, listen to her telling my sister the way SHE thought things should be done. (Roxanne refused the second obstacle, choosing a different one that was better to her liking, and the rest of the run was for training because she was disqualified.)
After her run, I told my sister, "Roxanne sure looked like she was having fun." My sister just shook her head.
