Balance Harness This harness has a lot of adjustment options, is lightweight and even comes in a version that has buckles on both the neck and body straps. You can attach a leash at the back or chest. Walk In Sync A front clip harness and leash combination that fits well. There are multiple points of adjustment and the ring on the chest sits in a good position to prevent excessively sliding of the harness while you walk your dog. Freedom No-Pull Harness A front clip harness that also has a ring on the back. I find fitting this harness is more difficult than Walk In Sync and Balance harnesses. If you want the option of attaching a leash to the dog’s back then give this a try.
