The stimulating, protruding nubs of KONG® Squeezz® Goomz massage teeth and gums to help clean teeth while rewarding appropriate chewing behaviour. Different textures and a durable material provide lasting fun while satisfying the dog's natural instincts. The squeaker provides long-lasting, interactive activity indoors and out. Note: Please never leave the pet unattended while playing. No toy is indestructible. To prevent injuries, the toy should be checked regularly for damage or loose parts and replaced if necessary.
