Purina Busy Bone Peanut Butter Treats: Surprising Durability Tested for Adult Dog Chew Bones We put these Purina Busy Bone Peanut Butter Treats to the test with our energetic adult dogs, and the results were… unexpected. Designed as chew bones, they surprised us with their durability-resisting the teeth of even the most determined chewers. The peanut butter flavor is rich and enticing, offering a satisfying crunch that balances texture and taste. Each treat comes in a convenient 6-piece pouch, perfect for on-the-go snacking or rewarding calm behavior. While they don't dissolve as quickly as softer treats, we found they provide a longer-lasting chewing experience, reducing the need for frequent replacements. The bark is sturdy yet not overly hard, making them safe for dogs with moderate chewing habits. Overall, they're a practical choice for satisfying a dog's need to chew without compromising on flavor or quality. We're impressed by their sturdiness and would recommend them for pet owners seeking reliable, tasty chew options.
