We've delivered 100 million toys to dogs like yours, and we made this Bark Super Chewer Kingpin Dog Toy for the busiest pups you know. Tough nylon provides a worthy challenge to even the heaviest chewers, while round rubber keeps the playtimes rolling (and spinning and tumbling). A vanilla scent keeps the ol' olfactories engaged, and Kingpin's spreadable treat grooves are perfect for peanut butter if you want to get your dog's tastebuds in on the action.
