# Playology Dual Layer Ring Dog Toy, Jumbo Size – Built for Power Chewers Meet the ultimate chew toy for dogs who demand durability and engagement. The Playology Dual Layer Ring features a revolutionary dual-construction design: a chewy, textured outer layer paired with a reinforced inner core that stands up to serious gnawing and tugging. This Jumbo size is engineered for large dogs weighing 50+ lbs, ensuring safe, appropriate sizing for powerful jaws. What sets this toy apart is Playology's proprietary Encapsiscent Technology—the all-natural chicken scent isn't just sprayed on; it's embedded microscopically throughout the entire material. Every bite releases fresh bursts of aroma, keeping dogs engaged up to seven times longer than unscented alternatives. The scent persists through cleaning, so your dog stays captivated session after session. Safety is paramount. The premium rubber is sourced from Singapore and rigorously tested against U.S. government standards, including ASTM guidelines and CPSIA protocols for toxins, lead, and phthalates. Maintenance is effortless—simply place it on your dishwasher's top rack (no detergent needed) to keep it hygienic without compromising the embedded scent. Perfect for interactive play, solo chewing, and satisfying natural instincts, this toy delivers the mental and physical stimulation power chewers crave—without treats, mess, or unnecessary calories.
