A wet dog shouldn't mean a smelly collarbiothane rinses clean and doesn't hold odor

BioThane is polyester webbing coated in PVC. Water can't soak into it, so lake water, mud and whatever your dog just rolled in all come off under a hose.

It stays soft and flexible, it holds up in the sun, and it will outlast leather or flat nylon.

How the collar is madehandmade in the usa

  • 01
    A ridge along the edge

    We chose BioThane with a raised ridge on each side. It's stronger than a flat strap, and it won't slip once you set the size.

  • 02
    Quick-release buckle

    On and off in a second, with our logo on the front.

  • 03
    Heavy duty metal D-ring

    Where your leash clips on. Any Mountain Dog leash fits it.

  • 04
    Box stitching

    Stitched in a box and X where the strap takes the load.
