Plush on the outside with a rope running all the way through the limbs, which is what keeps it in one piece when a dog grabs a leg and shakes. The squeaker sits in its own sewn pouch stitched into the seam rather than loose in the stuffing, so it survives longer than most. Double-reinforced mesh fabric, polyester shell, and the fill is made from recycled plastic bottles. 13" long. Built for medium and large dogs that play rough and then want to curl up with it. Spot clean.
