Our Biothane martingale dog 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.
