The flirt pole is excellent cardio work. Anything that provokes a dog to go all out, change direction, and go all out again it is just about as good as it gets in the cardio world.

Flirt pole is continual, non stop direction changing exercises for the dogs. Maybe Shaun T saw a bulldog doing flirtpole work and the light bulb went off. LOL...EWO
