i have gone through too many leashes to count in search of something that was comfortable for me to hold and strong enough to hold my 80+ lb rescue dog on the chance she wants to run after a bird (she is getting to be a good birdwatcher now instead of a birdpouncer, i'm so proud! but i digress). i love how light-weight and durable all the climbing rope leashes are from TFG - i now have 2. you really can't go wrong. as much as i love the look of their marine rope leashes, they are just a tad too heavy for my taste so the climbing ropes are a good alternative if you are looking for something super light and super durable/strong!
