I have a Boston terrier who has problems in winter with reverse sneezing on walks in the cold weather. I have tried other harnesses and found the buddy belt harness to be the best. There is no pressure at all on Iggy's neck when taking for a walk with this harness so I have found that he rarely reverse sneezes now. It is also easy to use and very adjustable so fits well over winter jackets. It is expensive but is worth paying the extra for.
