I just use a piece of PVC with some string, i wouldnt want to go out and buy one. The bait I use is this rubber squeak toy from big lots my dog loves, It actually works out great, because the weight and shape of the toy, its pretty had for him to catch, even on the spring pole, it ends up flying and bouncing around and taking him several times to catch it, Because of this, it provides a bit more "action" than some thing easy for him to catch such as rope, plus the toy squeaks keeping his interest. One thing I notice about my dog on the spring pole, is he whines when he sits there tugging on it, does anyone elses dog do this? He gets bored of the spring pole quickly if I am not there watching and encouraging him, seems to loose interest in it pretty fast, perhaps because he can never "win" by getting the toy? He will do flirt pole with me all day, I am guessing because he prefers the interaction with me over the spring pole.
heres an older flirt pole video with him, when I first started working the Foss command wit him.
