My 70-pound city dog loves to pull when he sees other dogs on the street and I have struggled with poorly-crafted leashes that are too bulky in my hand to give me a good grip, uncomfortable or awkward to hold, or too flimsy at the connection to give me confidence. The knot-a-leash elimates all of those concerns. A comfortable grip that is easy to grip and a powerful connector that will not open accidentally. I could not recommend strongly enough.
