The fact that breathing operations do not need to be declared is getting some publicity currently. I'm sure most people agree that this information is important to punters, especially given some high profile success stories this season. I don't know if there's someone out there compiling lists of horses that are known to have had operations, but on the assumption that there isn't yet, I thought I'd start a thread for forumites to add to when they hear of a case (with a link if possible) in the run up to Cheltenham where the trainer is good enough to let us know.
