Agility training is a healthy and enjoyable experience for pet owners and their dogs to share. It builds a dog's fitness, mental skills and confidence while strengthening the bond between pet and owner. With the broad assortment of TRIXIE agility products, you can customize courses for your dog's unique skill and fitness level. Each piece of equipment can be used separately at first, then later combined into a complex training course. The TRIXIE Agility Hurdle for Dogs is a height-adjustable training obstacle that accommodates jumpers of all sizes and skill levels. The hurdle bar lies loosely in the supports to prevent injury and properly train your dog instead of being attached. When not in use, it is fully collapsible for easy storage in our zippered nylon bag, included. Because this set is made of hard plastic, it is durable yet lightweight enough for even the kids to carry. An instructional booklet is included, sharing tips for designing the perfect fitness and training program. Quick and easy assembly. One-year warranty. Measures 48 by 45 inches.
