Cool video. I think what is used on the flirt pole is totally up to the owner and what the dog responds to. Couple consideration is the durability of the bait and its ability to withstand the dog's bite and weight without causing harm. Though unusual this works.
I typically don't let my dogs play with anything that is mine for use. No shoes, shirts, pants, slippers, gloves etc.. consequently I leave items outside and the dogs to not touch them. :)
Can we see your dog on the flirt pole?
