Dogs have an instinct to scavenge. Whether it's a treat-dispensing toy, a wastebasket, or underneath the dinner table, scavenging for food is simply part of their nature. With a KONG Stuff-A-Ball, your pup can satisfy this instinct with appropriate behavior. Its slots can be stuffed with KONG Easy Treat, KONG Snacks, kibble, or other yummy treats to turn it into a fun scavenging challenge. The Halloween Stuff-A-Ball is made with high-quality natural rubber, allowing it to withstand countless hours of chewing—and unlike nylon, hard plastics, sticks, or bones, rubber doesn't splinter and is gentle on dogs' teeth and gums.
