Outward Hound Unbelieva-Balls are the perfect dog toys for interactive fun! Each cute character contains a spikey light up dog ball inside for your pup to find. Watch as your dog uses its problem-solving skills to get the ball out, then toss for an interactive game of fetch! The lights get your dog excited and keep them engaged in play. Plus, these Unbelieva-Balls are built to last because they are made with K9 Tuff Guard: an inner layer of super durable materials that create a powerful protective shield. Reinforced seams make this one tough toy! Available in multiple characters.
