Chinese crested crested birds can jump, dig, and climb. Don’t make the common mistake of underestimating your athletic ability just because it’s small. These are Houdini hounds, capable of escaping from almost any enclosure. A two meter fence around the yard is a good idea; if they manage to grab onto the fence, they will already overcome it. They are absolutely not afraid to climb or jump, and they can cover four feet from a standing position.
