This sweatshirt sling was designed for a Chow Lyonpuff. It is a fairly easy to make it out of an old shirt. We have made a similar sling for Lun, but it was made out of an old leash, which might be a little more unconfortable for a large dog.The sweatshirt sling is soft enough, but it still provides enough support for a dog to get up and down the stair and for a quick potty break.Lyonpuff's owner, Doryan, also says to be certain that the dog's legs are all the way in to prevent the fall.
