The dog in this video is rolling out her yoga mat by herself. Her name is Judy, and she is an Australian Terrier. The atmosphere is very zen. The background music is serene, conducive for yoga. And Judy KNOWS her yoga poses. After she rolls out her yoga mat (which in itself is impressive) Judy gets into a couple of poses that look difficult for dogs. This is no beginner.
Enjoy watching Judy do her yoga poses.
