Our Old Soul Orbee-Tuff® Bones innovatively address issues that every dog experiences as they grow older and wiser: reduced vision and snout strength, weakened jaw muscles and brittle teeth. They were specifically designed for senior dogs whose chewing strength and urgency have waned over the years, but who still like a good, gummy chew. They are double soft, double minty, uniquely pliable and stretchy. As an added auditory bonus, the Bone naturally makes a "clicking" sound when squeezed together. Like all Orbee-Tuff® toys, Old Soul Bones are 100% recyclable, buoyant, bouncy, non-toxic and safely made in the U.S.A. Because Old Soul Orbee Bones were designed specifically for senior dogs, they are not appropriate for aggressive chewers. But they may be enjoyed by dogs of all ages who have gentle jaws. Only available in Large size (8" long).
