hmmmmmmmmmmmm tough one as I have had some wind suckers come through the yards I have run who were fine and one that it gave colic to on numerous occasions due to stomach ulcers
I know my first choice yard wouldnt take him. he has been seen to do it only occasionally and in every other aspect he fine. its just finding understanding YO in South Yorkshire.
I wouldn't be put off buying a windsucker - have known a few yards discriminate against them, but find they are the minority.
Why not ring a few yards in your area and ask if they would take a windsucker - at least you then know if you do go ahead and view this horse what your options are as to where to keep it.
