The Ruffians are a whole new breed of technology! This soft-textured toy not only comes with a tennis ball, crinkle, and squeaker inside, but also comes equipped with a STEEL SHIELD. The shield provides a durable lining, so your dog really has to work to sink their teeth into this one! Each toy comes with a Chew-O-Meter rating, ranging from gentle to tough, so you know just how well it will stand up to your dog and their canines. Even if they do succeed in tearing through the seams, there is a tennis ball toy waiting inside—two toys for the price of one!
