iFetch presents iFetch Frenzy. The toy works best indoors but can be used outdoors on a flat surface. It comes with built-in storage on the bottom to hold three miniature iFetch tennis balls, which measure 1.5 in. in diameter. The product has a hole on the top where the ball is inserted. The ball then rolls out one of three chutes around the base of the toy, keeping the dog guessing each time. The fast-paced, energetic and fun game is great for interaction between pet and owner, but many dogs will be able to learn to use the product on their own.
