This Bright Bag O Balls is a 7" plush ball-shaped bag that hides nine smaller balls for your pet to hunt out. The smaller balls are about 2.5" in diameter in come in a random assortment of bright colors. The interactive design of this toy challenges your pup to think and they get so invested in the puzzle the toy stays intact longer. Half the smaller balls contain squeakers as a delightful surprise for your pup and a reward for puzzling out this toy. The slit in the bag is large enough to allow your pup to sniff and grab out the smaller balls without hindering their mouths so that they're working their brain, not destroying their brand new toy.
