Great accessory!

I bought the line keeper to be a traffic handle. I wanted to give my dog more freedom on walks, but the longer leashes were making me nervous. My dog is strong! Having a short handle for emergencies or crossing a busy street makes me feel more comfortable. I don’t have to worry about her pulling the line through my hands when I have to keep her close. It has definitely made me more confident when walking with our new 10ft sport leash. I like the large clip and the length of the loop is perfect!

Can’t believe it took me this long to order one!

Where has this been all my life?! Holds my 20 foot and 10 foot long lines perfectly. There’s a quick tutorial on the HTH Instagram if you aren’t 100% sure how to use it at first but it’s so simple yet so effective. I will definitely be ordering more as my long line collection grows!
