A Great Buy. This leash's best quality is its simplicity. I am a first time dog owner. My puppy (6 months old) chewed on her nylon leash. After ripping one apart, I bought a better quality leash. She chewed through that, too. I bought this chain leash, and it works great. Sometimes she'll still chew it a bit, but it won't damage the leash in any way. I thought 4 feet sounded short for a leash (my nylon leash was a little longer), but 4 feet is actually a great length for a puppy. It lets her roam around a bit, but ultimately keeps her close to my side (and away from danger). The nylon loop lets me hold onto the leash comfortably without trying to grab onto a chain.I'm glad I bought this product, and if I ever get another puppy, I would order another one of these leashes.
