Like many great products, the Yapper Wrapper™ was developed because of a need we had.  Our little chihuahua, Gracie, loved to be under Greta's hoodie, right on her chest.  Greta had to hold Gracie inside the hoodie most of the time when walking or while standing.  At the time, all the industry had were big, bulky packs that were not so great for small breed dogs.  So we tried to come up with a very basic, minimal pack/harness to carry Gracie while under Greta's hoodie.  We had several prototypes we tried at our store with some of our customers and their pups.
