Not a durable toy.
Size: Drop Ball, Size: Drop Ball
I was very disappointed in this rope toys. It took one day for my Border Collie to destroy it. The rope is not a durable material at all. I had a rope toy that was like this one several years ago, but it was much more durable. It lasted a couple of years. I think this one would be great for a small puppy, but not for an adult dog. Very disappointing!

Fabulous play!
Size: Drop Ball
It is small for my 1 yr old girl boxer... my bad for not reading the product size details. The tug rope is great, but my rough boxer loved it too much and couldn't be trusted with it after much play. This toy opened the door for my purchasing tougher rope pull toys from the same brand.
