It's called the Together harness, from Karen Pryor http://www.clickertraining.com/node/3719 It's adjustable in 5 areas, it is the FIRST harness that really fits Seamus well. He's a standard poodle with a deep chest and fairly long back. It's funny, just as she says her poodle does, Seamus puts his head into the harness. He really likes it! From the website: Here's what makes these harnesses truly comfortable: The straps go around the neck and ribs, down the back, and down the middle of the chest in such a way that they don't rub and chafe under the armpits or interfere with the free motion of the shoulders, as many harnesses do. The girth goes around the ribcage so it doesn't shift forward and pinch. The harness unbuckles in two places so it goes on easily and you never have to cram the dog into it. The fastenings, both metal and plastic, are strong, durable, and hypo-allergenic. They are specially made with rounded corners so nothing ever pokes the dog. The woven webbing is soft to the touch, and soft on the dogs, but it's totally washable and lifetime durable—not just the dog's lifetime, but yours, too.
