The ball is molded from durable TPR sized at 2.5 inches in diameter, letting it fit medium Chuckit ball launchers as well as hand throwing. A crackle element is sealed inside the rubber shell, producing a crunching sound each time a dog bites down, with no separate squeaker mechanism. The outer material is built to withstand repeated chewing and fetching without breaking down or losing its crunch. Each package contains one blue ball intended for outdoor or indoor fetch and chew play with medium sized dogs. The toy requires no assembly and is meant for supervised play, with regular inspection recommended to check for damage or separated parts before continued use.
