MEET THE DUAL LAYER BONE: Built with a hard inner core, a chewy outer layer, and embedded with all-natural Chicken scent, this is the rubber dog bone your pup's been waiting for. Designed to mimic the texture of a real meaty bone, the Dual Layer Bone helps combat boredom and makes a great chew toy for dogs who are tough chewers. The Medium size is ideal for dogs 15-35 lbs. ENCAPSISCENT TECHNOLOGY: A dog’s sense of smell is 10,000x more powerful than a human’s. Dogs experience the world through scent, so we make interactive dog toys with the all-natural scents they love. Every Playology dog toy is embedded with an all-natural scent at the microscopic level. The fresh bursts of scent that are released with each chew will keep your pup engaged 7x longer than unscented toys. EASY TO CLEAN: Dirt and sand trapped on the surface of a toy can grind down your pup’s teeth, that's why we make all our rubber dog toys easy to clean. With our Encapsiscent Technology, the all-natural scent is embedded throughout the material of each toy, so no need to worry about washing away the scent your pup loves. Just rinse with warm water to clean and pat dry.
