I had to google flirt pole, as my first thought of it being a pole used by dogs to do pole dancing didn't seem very likely.
It looks like a good way of exercising a dog in a small space, but I'm in two minds with developing a dog's prey drive, if there are a lot of small animals where the dog lives or is walked, in case the game gets transferred to another animal that can be hurt. I can also see how it could be dangerous to the dog in the wrong hands, but I guess that is true for many things if misused.
