The TRIXIE Dog Agility Tunnel is a fun, healthy, and challenging activity designed specifically for puppies and small-breed dogs. In the sport of agility, this tunnel type is called an open tunnel. Small dogs or puppies can easily enter the tunnel through a 15-inch round stable opening before running through the durable, structured polyester 6.5-ft tunnel. The obstacle can be easily set up indoors or outdoors, including fillable stabilizing saddlebags to secure the tunnel. It is fully collapsible for easy storage in the zippered nylon bag when not in use. The open tunnel is also easy to clean - wipe it down with a damp cloth. An instructional booklet is included, sharing tips for designing the perfect fitness and training program. Suitable for puppies and small breed dogs.
