The martingale dog collar is a type of collar that is designed to prevent a dog from slipping out of its collar. It is made up of two loops– one that goes around the dog’s neck and another that tightens when the dog pulls or tries to back out of the collar, without choking the dog.

Features:

• Two loops: 1 around the neck, the other tightens when pulled.
• Safety device, not for training. No restriction, no discomfort.
• Collars fit loose when not engaged.
• Available in different materials, including fabric with patterns.
