Dog get loose and chases horses!!! Part 1

A neighbor brought her dog over for me to bathe today. She had a harness on it instead of a slip leash. When the dog saw the horses it immediately slipped out of the harness and took off after the horses. There was no stopping the dog there was no catching the dog. I finally used a little psychology and told the lady to go get her truck and act like she was leaving and the dog instead of chasing the dog. Tune back in to see if we caught him in part 2.
