I just wanted to add that my friend has a wind sucker. My friends horse will suck wind using her pasture mate. My friend had a consultation from a professional trainer...she said that if the horse wasn't being kept in the stall to much then it was pretty much something you can't do anything about. She said you can try and keep the horse busy all day and it might help...but not even a cribbing collar would help in the long run. If the wind sucking bothers you or you are worried about the horses health...I would pass on it.
