1.5" Biothane Martingale

1.5” Biothane Martingale Collar – Slip-On, Custom Made to Size
 
This heavy-duty 1.5” martingale collar is built for strength, security, and simplicity. Designed to slip over your dog’s head, it offers reliable martingale-style correction — gently tightening when pressure is applied, and releasing once relaxed — all without buckles or clips.
 
Custom Made to Size
Each collar is handcrafted to fit your dog.
Please refer to the measurement guide in the listing and provide the measurement around the widest part of your dog’s head (not the neck size). This ensures the collar can slip on comfortably while still tightening effectively.
The 9” stainless steel chain will allow the collar to tighten by up to 9 inches when engaged.
