The Hol-ee Roller is built from soft, stretchy natural rubber formed into an open, honeycomb-style sphere. Its hollow, multi-hole construction lets owners tuck treats, kibble, small toys or ice cubes inside so a dog has to work to remove them, turning playtime into a mental exercise. The same rubber body also functions as a fetch ball, tug toy and chew item, with a soft texture that is gentle on a dog's gums during chewing and teething. Each toy is seamless and comes in a single, ready-to-use piece with no assembly needed. Colors are assigned at random from an assorted mix and cannot be requested. The toy is intended for supervised play and is not designed to withstand sustained heavy chewing.
