This listing is for a 1.5" BioThane martingale collar that tapers to 1" near the chain. All of our chains are made of stainless steel with a durable finish. Please note that although baked with two coats of a clear gloss finish, these colors can fade over time.
The chain allows approximately 3" of fitting range. Your requested size will fall near the middle of this range.
For a looser, anti-escape fit (rings just touch when fully tightened; not intended for correction): Measure your dog’s neck behind the ears and add 1" to that measurement.
For a snugger fit (rings do not touch when tightened): Enter your dog’s exact neck measurement. If the head measurement exceeds the neck measurement by more than 1", we recommend adding a buckle for easier on/off and to help maintain a proper fit.
