Features: Two Interactive Modes As a mentally stimulating and entertainment toy for dogs, Best Dog Toy Ball is specially designed for active or timid puppies or bored adult dogs. Upon being turned on, it will automatically roll, shake or bounce. There are 2 interaction modes: Normal and Smart among which you can switch to make it suitable for different dog plays. The cool LED light will also be turned on to catch your dog's attention immediately. Ideal for Small Breeds This dog toy ball is 2.05 inches / 52mm in diameter that is most suitable for dogs weighing up to 35 lbs, but not suitable for aggressive chewers. We suggest your supervision during the fun play and instruct your doggie how to interact with the ball properly instead of just chewing on it, which is also good for enhancing the relationship between humans and pets.
