Help your pup refine his or her agility skills with hurdles. Vary the challenge level with different shapes and heights. These Hurdles provide a fast-paced obstacle with lots of excitement. The Pentagon Hurdle is larger with a customizable routed design (customization is an extra charge). Hexagon is suitable for most dog sizes, and builds coordination and strength/conditioning, while Pentagon is ideal for larger breeds. These jumping products can be used in a row, alone, or offset for different challenges. Use one hurdle or group them together for an extra challenge.
