Our gorgeous martingales are especially created for the real ‘Harry Houdini’s’ out there. They are the perfect choice for dogs that need a little more control than a regular designed collar, or for those that can slip out off their collars easier than others, depending on their fur texture or shape of their neck compared to their head. Our martingale makes it hard for a dog to slip free as our martingale tightens slightly when the dog pulls on the leash, but not so much where it will choke the dog or harm the neck in any way. Our martingales will soften with continued love and use and can be machined washed.
