Cetacea chain martingale collars are one of your best choices for a quality training collar. Dog trainers and vets recommend this type of collar when a correction collar is needed. The martingale collar is fashioned after equine designs providing a form of a limited choke collar. The exceptional feature of a martingale collar is that the slip function can be limited to not over-choke your pet. To make the Cetacea martingale more practical than other brands it uses a quick release buckle so that the collar can be put on or removed from your dog’s head without having to readjust the length.
Cetacea collars are sewn using a unique Bar-tack stitch which is remarkably stronger and more durable than traditional "Box X" stitch used by other manufacturers. The Chain is made from steel and is coated with a durable and rust resistant nickel finish while the quick release snap is made of high quality Acetyl plastic.
Martingale collars are useful for narrow headed breeds or any dog who has a tendency to slip out of regular buckle collars. Properly fitted martingales are accepted by many venues for use in Rally Obedience trials.
