Loved the leash, puppy bit it in half.

The leash looks great. The locking caribener seems very secure. My husband doesn't like the way it feels in his hand (we have the thinner leash). Unfortunately after using this leash for about a week, my 6 month old puppy was lying at my husband's feet and bit the leash in half. Her adult teeth have been coming in and she's been chewing more than usual. Obviously not high tail's fault but it's hard to leave 5 stars for something that broke so quick. I would not recommend this for dogs that grab the leash or chew.

The BEST leashes!

We have a variety of leashes and long lines from HTH. They are amazing! The customization options and colors are perfect for our needs, and we get so many compliments! The carabiners on the sports leashes are lightweight and easy to use. 10/10 long line!!

Thank you Erin!!! We love the lightweight carabiners too, so easy and safe!

Great quality long line!

I have had this long line for just over a month and use it nearly every day. It's comfortable, easy to clean, and looks great! I'm sure I will order another but I will probably get the regular snap next time, the carabiner is not the easiest to use. That being said if it were the only option I would still reorder! Biothane is worth the investment!

So glad you are enjoying your long line! The BioThane is so easy to care of! Thank you Trina!

Love high tail hikes!

100% recommend them! After ordering a 30 ft leash, we knew we needed more. We currently have the a 10ft, 15ft, and 30ft because these are fantastic. So durable, easy to handle + clean, customizable, and pretty!

Lucia, we love hearing how much you love our long lines! Thank you!
