The Holt Control Harness is a very effective and humane form of control that applies an even amount of pressure under the girth instead of pinching the dog behind the front legs. This harness is constructed of durable braided nylon with metal hardware. This training tool will give you an alternative to the chain collar, alternative training collar etc... when you are training your dog not to pull or tug on his lead. This comes in three different sizes to accomadate most dogs.
