The KONG CoreStrength Ball is a durable rubber chew and fetch toy with a multilayered internal construction. It's designed to satisfy natural chewing instincts while standing up to longer play sessions than a single-layer rubber toy.

The build is what sets it apart: a textured rubber exterior over a multilayered, reinforced inner core. The layers add toughness for chewers without making the toy hard enough to damage teeth. The textured surface is genuinely useful for grip, both for the dog and for the owner picking it up. Available in S, M and L sizes. Suits moderate to enthusiastic chewers. Pairs well with KONG's stuffable Easy Treat paste for extended engagement.

The CoreStrength range fills a useful spot in KONG's lineup between the standard rubber line and the heavy-duty Extreme, durable enough for serious chewers without being so firm that gentler dogs lose interest.
