Sherpa started it all fifteen years ago and is a well-known name in the dog carrier world. With state of the art carry on dog bags suited for traveling in cabin on the airlines, Sherpa has not scrimped on style and makes choosing just one carrier difficult, so you may need to buy two so you can change your mind at a moments notice, depending on your mood! The Jazzy SoHo Backpack comes with an adjustable over the shoulder strap that converts to a backpack strap.
