DURABLE!!! ❤️❤️ These are great toys for pupies. We bought large balls too.. The small balls are great for puppies... the large Ridge Ball is PERFECT for adult dogs. If you have an adult dog... this is a great treat to bring to your older dog that's at home. Getting a new puppy? Do not forget about the older canine at home that might feel left out. Small balls for puppies going home... big ball for the existing dogs at home or tuck it away for the future. These balls are EXTREMELY durable! Love this product.
