Martingale dog collars are really helpful by trainers for canines who slip out of conventional buckle collars. Martingale-style collars are designed to tighten if your dog starts to tug. When your dog stops pulling, the collar loosens automatically, so the collar is only tight when it must be. Recommended by veterinarians and trainers, our dog harnesses and headcollars work by safely and gently discouraging your canine from pulling on the leash.
