Tre Ponti harnesses are simple and easy to use. These are top quality harnesses designed and handmade in Italy. The Easy Fit design looks like a boomerang with the center cut out. You place your dog's front legs into this center opening, then simply pull the ends up and fasten them at the dog's back. The result is a smooth band across the chest and another around the rib cage. There are no "armpit" straps to cause chafing, and the chest band stays put so it won't choke the dog.
