Our best-selling leashes
Here's what pet parents have to say
Finally, a leash my dog can't destroy.
I've spent hundreds replacing chewed-up leashes. This one's held up for months even with my 90-lb shepherd mix. The chew guarantee gave me peace of mind, but I haven't even needed it yet.

It's soft in my hand even on long hikes.
Most leashes either dig into my wrist or give me rope burn when my dog pulls. This one's surprisingly lightweight, flexible, and super comfortable no matter how far we go.
Marcus D., Colorado
I love knowing it's eco-friendly and built to last.
I try to avoid wasteful pet gear, but most sustainable options feel flimsy. This leash is the real deal: strong, secure, and made from upcycled climbing rope. I feel good using it every day.

@mountaindogproductsFrequently asked questions
What makes Mountain Dog leashes different?
They're hand-assembled in Phoenix, Arizona from upcycled UIAA-certified climbing rope, the same rope used by professional climbers. No cheap hardware, no mass production, and a lifetime guarantee that even covers chewing.
What does the lifetime guarantee cover?
Everything. If your dog chews it, we'll replace it. If it frays or fails, we'll replace it. For life, no questions asked.
Are they strong enough for big dogs?
Yes. The 10.5mm dynamic climbing rope is rated to hold over 4,000 lbs and is built specifically for dogs that pull, lunge, and test their gear. Mini options are available for smaller dogs.
Which leash should I choose?
Take the Find Your Leash Match quiz and we'll recommend the right leash or bundle based on your dog and how you walk. Not sure between a slip lead and a clip leash? The quiz sorts that out in under a minute.
