With the weight of a pet on your shoulder or back, your speed slows down and you start to get tired faster from carrying more, but when you're able to walk with a wheeled pet travel system behind you, you're free again. This 2-in-1 Aosom design allows easier pet portability on walks, while also attaching to bicycles, and offering safety features to stay highly visible and keep your furry friend safe. With a tall red flag and a reflector, you can alert those around you from multiple directions.
