Large. Yellow Unicorn. The MIGHTY® Bone is sure to become your dog's favorite toy! This toy is made with multiple layers of material and durable seams located on the inside. There's NO stuffing! The inside of the toy is a plastic core in the same shape as the toy. If your dog removes the outer fleece covering, there's a whole new toy inside! Did we mention it also floats and is machine washable for extra fun and convenience? Our toys are built to last, but keep in mind that no toy is "indestructible". MIGHTY® toys are designed for interactive play and not for chewing.
