Dogs can't resist the squeaking fun from HERO Squeakables! Each toy features a long-lasting squeak to engage dogs longer. Originally included in dog toys to simulate the sound of prey, squeakers have become the mainstay of the most engaging toys! Keep the curious canine busy or have some chase, chew and fetch fun with HERO Squeakables. This ball has built in chewing and handling nubs, making it easier for dogs to use. It is great for throwing, tossing and chewing. Rolls and bounces erratically. Add treats for extra exploring fun!
