[Two Interactive Modes] This mentally stimulating and entertaining dog toy is specially designed for active or timid puppies and bored adult dogs. Once turned on, it automatically rolls, shakes, or bounces. It features two interaction modes—Normal and Smart—allowing you to choose the best option for your dog's play style. The built-in LED light activates to immediately capture your dog's attention. [Perfect for Small Breeds] This dog toy ball has a diameter of 2.05 inches (52mm), making it ideal for dogs weighing up to 35 lbs. It is not suitable for aggressive chewers. We recommend supervision during playtime and guiding your dog to interact properly with the ball instead of chewing it, which can also help strengthen the bond between you and your pet. [Gorgeous Colors & Safe Material] When activated, the LED lights enhance visual stimulation for your pet, encouraging natural behaviors like chasing and pawing. We prioritize pet safety and well-being. The ball’s outer shell is made of durable, non-toxic, BPA-free plastic that resists easy chewing. It is odorless, easy to clean, and gentle on your dog’s teeth and gums. Additionally, it operates quietly on hard floors. [Automatic Obstacle Avoidance] Equipped with a built-in intelligent motion sensor, this toy automatically detects obstacles and reverses direction to continue moving, keeping play unpredictable and engaging. You don’t need to worry about it getting stuck in corners.
