Get the same lead that we use with every dog we work with. Get rid of the chokers, prong collars, and harnesses. Not only is the Immediate Correction Collar the key to getting your dog to walk on a loose leash, it is also the way we execute one of the three non-verbal corrections we use to mark and remove any unwanted behavior. George sews each and everyone by hand using mountain climbing rope. They are guaranteed for life for any craftsmanship defects. Damage from chewing is not covered. Choose between the puppy/toy breed model or the original. If your not sure which to order, just tell us what type of dog you have.
