I was a bit hesitant at first, But it is sturdy, which is a good thing, and I can remove it fairly quickly when I need to. I weigh 175lbs and have an 80lb Labradoodle who is pretty strong. When he pulls, I feel it, but I am not jerked off balance, probably because the pulling is right under my weight. Mostly I feel it when I'm going uphill and he decides he wants to hang back! I used to feel so guilty leaving poor Fez behind so I could get a ride in, now I can take him with me! Fun!
Bought this product after many bike rides with my dog by my side. It's great for medium or larger dogs that can keep up with you while you're biking. It's flexible and avoids all those tangles and hassle of holding or clipping a standard leash. I gifted this also to friends who bike with their dogs often - they all love it! Highly recommend!
The leash is a game changer. Our dog loves it and I highly recommend it.
