Spunky Pup's Double Wall Hydrant is the perfect way to treat your pup. Made in the USA with thick-walled Rubber-like material and textured for healthy teeth and gums, stuff this Hydrant with peanut butter or your pup's favorite treats. Completely free of PVC/vinyl, phthalates, lead, petroleum, and heavy metals, the Hydrant is top shelf dishwasher safe. *Not recommended for tough chewers. These toys aren't going to hold up to Pups that love to gnaw. We recommend using these as a treat dispensing play toy. They are durable in the way that they are very heavy. Please always practice supervised play!
