Mixy the Agility Chihuahua goes running and leaping through the course in her first agility trials in August 2009, along with her owner/trainer Megan Magnant, who also trains her border collies as agility dogs, and other sports. They all live in Oklahoma City.

Megan said, "I got Mixy when she was 4 years old. Mixy started out just being a family pet, but she turned into a pretty good agility dog. She is pretty chill all the time, sleeps a lot. But take her out to the agility field and she tears up the course."

The video below for Mixy is just so charming, and what a splendid way to bond with one's dog while insuring the heart-health and longer life of both human and canine.
