The iSqueak toy is a vibrant and rugged natural rubber toy infused with vanilla extract that squeaks. Our long lasting toys are fashioned of thick-walled heavy duty rubber and finished with a long-winded squeaker. These tough rubber toys were developed for and by pet owners in order to provide a superior outlet for interactive fun between dog and owner, as well as for the play and exercise of the dog by itself. Pliable, resilient natural rubber has proven itself to be the best material to satisfy the dog's normal craving to chew.
