Your small dog collar is ready before the trail is. Whether it is a puddle crossing, a rainy morning walk, or a full-on creek scramble, the Cosmos Mini is sized and built for dogs who move through the world at full speed without needing heavy gear to keep up.
BioThane® construction. The Cosmos Mini is made with BioThane®, a waterproof dog collar material that resists bacteria and mold growth, so the collar stays stink proof even after repeated wet adventures. No drying rituals, no lingering odour between walks.
Lightweight fit. The Cosmos Mini is a lightweight dog collar that lets smaller dogs move freely without the collar adding unnecessary weight or bulk through the day or on the trail.
Waterproof build. Built to handle rainy days and wet adventures, BioThane® sheds water and wipes clean rather than absorbing it, which means the collar keeps its shape and feel across seasons.
Stink proof. Because BioThane® resists bacteria and mold growth, odours do not build up the way they do in fabric or webbing collars after repeated exposure to water, mud, and general trail life.
Secure fastening. The black metal buckle keeps the collar securely in place during outdoor activities, so you are not second-guessing the fit when your dog decides to bolt after something in the underbrush.
Please note that COSMOS MINI does not offer dual colour options.

We got the Cosmos Mini for our 15lbs dog and it’s perfect for her! I highly recommend it for smaller dogs

Love how mysticaltails offer 3/8” biothane collar for small dogs… got ours a couple months ago and love how light it is

Love this collar! The collar is nice and thin and holds my pups name tag nicely. Because the collar is thin, it pairs nicely with our Boa slip lead and isn’t too bulky on my dog’s neck.
