Hol-ee Cow! Made with the same durability JW customers have come to know and love, we've created a new spin on the Hol-ee Design. JW's® Hol-ee Cow™ is specifically designed for small dogs and features the same non-toxic, durable, super-stretchy design as the original Hol-ee Roller® Designed with small mouths in mind, the Hol-ee Cow works great as a chew toy, fetch toy, and treat toy.
