A dog run is a designated area where dogs can play and exercise off-leash. These spaces are typically fenced to ensure the safety of the dogs and to prevent them from wandering away. Dog runs often include features like benches for owners, agility equipment, and separate sections for small and large dogs. Dog runs can be found in parks, urban areas, and community spaces, providing a safe environment for dogs to socialize and burn off energy. They promote physical activity and can help improve a dog's behavior by allowing them to interact with other dogs and people in a controlled setting.
