sorry but i wish you luck.
I will try to get some pics of a horse at our yard who has windsucked for about 8 years.

To date he has had the vet out at least twice yearly for chronic colic through windsucking.His gums bleed where he has worn his teeth down,his owner puts up rope and toys for him as they are softer on his mouth and last month he had the vet out three times in one week resulting in the last two being on the same da and he was taken in for surgery at a cost of thousands,he isn't insured for colic induced by windsucking anymore???

When he is out in the field he stands and windsucks on the posts,when they put him in electric posts he did it on his field mates neck!!then he tries to do it on the chest buckles of the rug he is wearing!!!!Water buckets anything he can get his teeth into.
