I like the freedom the Flexi 2-8 Retractable Leash provides for my older dog when he is walking. I originally tried to use this leash when my dog was still in the "puppy stage" but found that it was not a good fit for an energetic puppy. He pulled too much on the leash and the length the leash extended was too far for him. My puppy would get distracted and did not walk well on the Flexi 2-8 Retractable Leash. I decided to put this leash away until my puppy was a little older and just recently started using this leash on our walks again. The Flexi 2-8 Retractable Leash is perfect for an older, slightly less energetic dog. The extension length is perfect and the locking mechanism is strong. I can extend the leash out some of the way, lock it, walk my dog, and the leash stays in the same position during the time we are out walking. Overall, I am very impressed with the Flexi 2-8 Retractable Leash. While I would not recommend it as a leash for puppies, it is a perfect choice for older dogs!
