There is no substitute for a well fitting blanket. That being said, you do have a few options. Dover and SmartPak are wonderful with returns and will let you try the product until you get just the right fit. Saratoga Horseworks, however, will custom fit any of their blankets/turnouts etc. for your horse. I have purchased items from them, pinned them up so that the fit is what I want, shipped it back and they have done alterations for me. Their prices are about the same as you would pay for any quality blanket/turnout. If you need something immediate – go to one of the Dover Stores.
