Spunky Pup uses all-natural vegetable dyes. Each Organic Cotton toy is thoughtfully hand built using double-layered and double-stitched construction. Toys feature built-in squeakers to keep dogs engaged and entertained. In a further commitment to natural materials, our Organic Cotton toys are filled with all-natural Coconut Husk fill. Coconut Husk, the byproduct of coconut processing, is a natural, dog-safe material and its reuse helps to reduce landfill use.
