Gingham All the Way MartingaleOur fun and fashion infused Martingale collars are a gentle way to have control over your dog. Perfect for dogs that pull or easily slip out of their collars. Martingales work by creating an even tension around the neck to avoid neck and throat injuries. Like all of our collars, they are made from high tensile strength nylon webbing with sewn on polyester and nylon ribbons, and are stain and fray resistant. They are designed to last a lifetime! PLEASE
