The KONG Signature ball is a great way to encourage an active and healthy lifestyle for your dog. It's ultra-durable and perfect for interactive play and fetch games, bouncing higher than a tennis ball. This ball is made from safe, non-toxic materials that won't harm your dog's mouth and is designed to last for those dogs that can't get enough fetch. It's also available in different sizes so you can choose the perfect size for your pet. This Medium KONG Signature Ball comes in a pack of 2, however it is not suitable for puppies under 36 weeks or dogs that are known chewers. If you find that the ball is damaged, discard it immediately and replace it with a new one. Supervise your pet when playing alone with this ball if your dog is an aggressive biter.
