CS choke chrome dog collars are strong and durable, featuring a fine mesh chain structure made of chrome steel. The useful end rings allow for easy attachment of the leash. These collars indicate training your dog, and are particularly solid and safe as they do not break or slip when the animal is pulled very strongly. During use, it is always recommended to exercise great caution and not reach the point of "choking" the dog, which causes it pain. The collars are available in eight different sizes to fit animals of any breed. Size A of the collar mentioned in the sheet does not include the rings.
