The KONG Classic is a versatile toy that helps address a range of common dog behaviours including chewing, boredom, barking and crate training, while also providing valuable mental stimulation. Its unpredictable, erratic bounce keeps dogs of all breeds engaged during play, and the hollow interior can be stuffed with kibble, peanut butter, or KONG treats for an added challenge and longer play sessions. It's also top rack dishwasher safe for easy cleaning. Made from durable natural red rubber and recommended by vets and trainers worldwide, it's suitable for average chewers. Like all KONG products, it's made in the USA with globally sourced materials, backed by nearly 50 years of experience in pet enrichment.
