YOUR DOG DESERVES THE ENTERTAINMENTMaterial: Plastic
We call it UFO UNO loves playing with it getting treats in between photos.
Very durable no teeth marks left on rubber ring. Easy for UNO to tilt and holes are perfect size not to small we even put diced chicken in it sometimes. Easy to wash easy and clean. Once putting treats in the top of ball fell on floor off table it survived no cracks . 10 stars very well built strong toy.
