The muddy walk ends at the sink

Rain, mud and lake water sit on top of BioThane instead of soaking in, so there's nothing left in the collar to smell. Rinse it, towel it off, and it's back on your dog before dinner.

Where cheap collars give out

Close-up of the ridged edge and box stitching on the black collar

Ridged edge

A ridge runs along the edge of the strap, so it grips the slider. The fit you set in the morning is still the fit after the walk.

The Mountain Dog quick-release buckle on the red collar

Quick-release buckle

Squeeze the sides and it's off. Handy at bath time, at the groomer, or with a soaked dog at the back door.

A rope leash clipped to the metal D-ring

Metal D-ring

Box-stitched into the strap. Every Mountain Dog clip, carabiner and hands-free leash clips straight on.

A fit that stays put

Two fingers slid under a fitted collar

Two fingers of room is the right fit

3/4 inchNecks 13" to 20.5"The width for our Mini leashes and their lighter clip.
1 inchNecks 16" to 26"The width for our Standard leashes.
  1. Measure the neck with a soft tape, where the collar will sit.
  2. Pick the width whose range covers that number.
  3. Set the fit so two fingers slide under the collar. The ridged edge holds it there.

No more frayed, faded collars

BioThane is coated, so it won't fray at the edges or fade like nylon.

Frequently asked questions

Will it work with my leash?–

Yes. Every Mountain Dog clip, carabiner and hands-free leash clips to the heavy-duty metal D-ring.

Will the color fade in the sun?+

BioThane is UV resistant, so the color holds up on sunny walks.

Is BioThane vegan?+

Yes. It's a cruelty-free alternative to leather, and it outlasts leather and flat nylon.

What does the collar warranty cover?+

Defects in manufacturing and workmanship, for the life of the collar. It doesn't cover normal wear and tear, chewing, damage caused by accidents, or the natural breakdown of materials over extended time and use.

Collars in new, resalable condition can be returned within 30 days of receipt for a refund or exchange. See Warranty and Refund Policy for more information.
