Martingale collars or greyhound/sighthound collars are a perfect choice for stylish hounds with narrow heads, or other dog breeds who want to benefit from the martingale system.  They’re like magic! The collar has two loops - a large one for the head and a small one with a D-ring attached. When your hound pulls, the small loop tightens, keeping their head safe and secure without choking. Say goodbye to an accidental slip out! When there’s no tension, it sits comfortably and snuggly on your dog’s neck. No need to constantly adjust it either - it only tightens when engaged and goes back to normal when the tension is gone.  Learn More
