The GoughNuts Pro 50 Black Ball Dog Toy was designed to give dogs a safer, tougher ball. Each GoughNuts Ball is designed with a multi-axis groove system for the purpose of helping to aid in breathing in a worst case scenario air blockage situation. Sizing is the most important factor and therefore be sure the ball is large enough for your dog (the ball is 3 inches in diameter). The GoughNuts Black is guaranteed for life. If the ball becomes damaged simply send it back to GoughNuts for a FREE Replacement (details below). The GoughNuts Black Ball has great bounce, floats and it is very durable. The GoughNut Ball Black is an interactive toy, not for constant chewing! The GoughNut ring design is the most durable design and should be used for power chewing. Never allow your dog to chew on these toys unattended.

• A natural rubber ball that utilizes engineered carbon reinforcement for added durability
• The two layer design is built with a red safety indicator that lets you know when it is time to take the ball away
• Designed for tough and aggressive chewers
• Easy to clean: just use warm water to wipe GoughNuts Rings clean
• Made in USA
• Free Replacement Warranty.

I've used many chew toys over the years but none have been able to hold up for very long besides Goughnuts. Only once have I had to send back a destroyed toy and Goughnuts replaced it for me no questions asked.
