Biothane Martingale Collar

Size Find your size ? 14


Our Biothane martingale collars are ready for adventure! These collars feature solid brass hardware, including a buckle style adjustment mechanism with a low-profile strap keeper and martingale chain. 

Finished with a brass Strange Tails moon charm, our Biothane martingale collars are proudly handmade in our Vancouver, Canada studio.

Please note: The martingale chain is solid brass and will oxidize as it ages. Since the chain sits directly on the fur, please keep in mind that it may discolour the fur of light coloured dogs. Regular cleaning of the hardware with mild soap and a damp cloth can help to prevent this. 

About Biothane

Biothane is a coated webbing material that is strong, flexible and lightweight.

It's also waterproof, stink-proof, and stain-proof, making it extremely easy to care for and clean. This makes it our material of choice for pups that love to swim or get dirty!

We use the "Super Heavy" Biothane for all of our leashes, handsfree adapters and classic collars which has a substantial and luxe feel to it. Our adjustable quick release collars and martingale collars use the "Standard" Biothane.

Care Guide

One of the best things about Biothane is how easy it is to care for and clean. Simply soak your gear in warm soapy water as needed. You can use an old toothbrush to scrub away any stubborn dirt. Rinse away any remaining dirt and soap residue with clean water.

Solid brass hardware naturally oxidizes as it ages. It can leave tarnish marks against the biothane, especially on the lighter colours.

To remove tarnish marks, we recommend using a magic eraser or a small amount of rubbing alcohol. Please ensure to thoroughly rinse your product with soap and water before using your gear again.

While Biothane is easy to clean, it does still get dirty. Please keep in mind that lighter colours will show dirt and tarnish marks more easily, and will require more frequent cleaning to keep looking fresh!

Biothane Martingale Collar

Melissa Blewitt
Prettiest collar my pup has had!

Finding a martingale style collar for my large dog has always proved challenging, finding one I actually liked the design of is near-impossible. This is the first time I've been able to get a collar for her that's beautiful and functional. The stunning colour, option for brass hardware, and ability to buckle and unbuckle (I never find this option on martingale collars!) are fantastic. The biothane holds up really well and wipes clean so it doesn't pick up odours like her previous fabric collars have. I will be purchasing a second for my new rescue dog!

Just What We Wanted!

This well designed and constructed collar and leash is better than we anticipated. It’s stylish, but practical.

Absolutely love - well worth the investment

Strange Tails martingale collar, hands-free adapter set and long line are part of my daily gear. Quality is amazing and incredibly sturdy. Hardware is heavy duty. I love to support local when I can and know these are hand-made to order (not mass produced) gives me reassurance that they check for quality control and stand by their product. I admit that they are on the expensive side, but honestly 100% worth the investment. I have a reactive dog and that sense of security and peace of mind having her attached to me when walking is worth it.

Great customer service - Savannah and team are absolutely amazing!

It's heavier than I expected, but I got used to it after time. Would recommend getting the narrow width if you worry about the weight or have a smaller dog.

Best Durable Collar

Love the quality and look of this collar. My husky loves playing in any water sprinklers he sees on our walks and getting in any body of water on our hikes so his collar is constantly dirty. His new martingale collar is easy to clean and has also been durable when he sees a squirrel or cat and it gets pulled when walking on leash. Bonus that the brass hardware makes it look classy and timeless. Love it!
