Commonly known as training collars, martingale collars fit looser around the neck when the chain is not tugged on. However, if the two rings of the control loop touch when it is pulled tight by the leash, the collar is too loose.
*Always consult with a trainer before considering purchasing a martingale collar. These products should only be used once owners are taught how to properly fit and use the tool on their dog.
These bad boys is a go-to option for training a beast of a dog we like to say.
