The X-Link™ is a reflective everyday dog harness with leash attachment points situated on both the front and rear of the harness. The front D-ring is best for dog training and teaching your dog to not pull on the leash, whereas the rear D-ring allows the X-Link™ to be used as a standard dog walking harness. The X-Link™ harness has been designed with one goal in mind - to help you enjoy a more comfortable walking experience with your dog. The front D-ring offers training and behavioral benefits, with the option to switch to the rear D-ring at any time to use as standard dog walking harness. You can also train your dog to a point where the front D-ring option is no longer necessary, at which point you can switch to the rear D-ring without having to purchase another harness. Choose the X-Link™ Harness for more control over your dog. Once your dog is under control, you can both look forward to more enjoyable and comfortable dog walks.
