Built to last for active dogs - Robust construction with a flexible buffer layer resists deformation and bursting under high-intensity use. Designed for large dogs that love aggressive chewing. Exciting chasing action - Dynamic rolling paths and spontaneous chasing engage dogs, with an irregular bouncing design that supports stress-relieving interactive play. Convenient to use - Made from quality PVC material for a sturdy, rough-play ready toy. Includes a zippered layer to improve strength and durability. Practical option - Ideal for fetch and throw activities. The elastic composition helps protect teeth, supports discipline development, and strengthens the bond through shared moments of fun and exercise. Use scenarios - Outdoor fetch with a strong chewer: toss the ball for rolling, bouncing, and chasing; built to withstand tough chewing and energetic play in open space. - Indoor play on bad weather days: irregular bounce keeps the dog guessing, providing engaging mental and physical activity in a confined area. - Training and recall sessions: use during fetch drills to reinforce obedience while the elastic, tooth-friendly design aids controlled play and bonding.
