Great lead, but chafed dog
I have the 5m and 10m versions of this lead, and I love the 5m one. It's light and strong and easy to grip.
The 10m version is thicker and less flexible. Seems extremely strong but we've had some mishaps with it. Because it is rubberised, it can wrap around and grip the dog's skin, it doesn't slide off like some other leads. When it grips, the rubber gives friction burns on hairless places. Not so good for our staffie-x's underlegs, so we've had to discontinue use as he was getting lead burn.
