The dog ball built for the dogs that destroy everything. The FloTek Dog Ball is made for power chewers and high-drive dogs that shred ordinary toys in minutes. Crafted from 100% natural rubber and made in the USA, it stands up to intense fetch, catch, and chew sessions that send tennis balls and hollow rubber to the trash.Built for aggressive chewersBelgian Malinois, Dutch Shepherds, German Shepherds, Rottweilers, and other strong-jawed breeds go through toys fast. FloTek's dense natural rubber takes the toughest chewing and holds its shape, so one ball outlasts a pile of replacements.Engineered for safer play: The patented FloTek airflow groovesFloTek's signature grooves are a safety feature, not just a grip. They channel air around and through the ball so your dog can keep breathing during intense fetch, and they help prevent choking by letting air pass through even if the ball ends up at the back of the mouth. The same grooves give your dog's teeth something to grab, so catches on the run are cleaner and easier.100% natural rubber, made in the USANatural rubber is tougher than synthetic alternatives and gentler on teeth and gums, and every FloTek Ball is molded in the USA.
