The KONG® SHAKERS SHIMMYs are the ideal playmates for any dog. Faux leather and shiny and fluffy textures keep your four-legged friend interested, while a soft squeaking sound and crackling noises encourage shaking and provide plenty of healthy exercise. Note: Please never leave the pet unattended while playing. No toy is indestructible. To prevent injury, toys should be checked regularly for damage or loose parts and replaced if necessary.
