My boyfriend’s girl dog is a nightmare (our precious little nightmare). We were able to get this on her and secured! She is around 60 lbs, a weirdly shaped pitbull mix and this set fit her comfortably! The leash was perfect and helped with training and controlling her high energy on a night walk. She did so well with this leash and already looking forward to adding more to our collection. My first dog goods purchase and the story behind this brand is touching!
