Extra strap for puppies and smaller dogs. The strap is used to adjust the harness from puppy age to an adult dog. The strap is fastened with Velcro in the front loops and it will be easily removed when the dog is fully grown. This strap can also be used to customize our harnesses to smaller dogs where the harness otherwise would have been too big. Note, the strap should be fastened around the rear wider ribbon (see image), not around the colored detail ribbon. Extra Strap Small fits Sighhound Harness XS and S. Extra Strap Medium fits Sighthound Harness M, L and XL. Extra Strap Large fits Sighthound Harness XXL and XXXL.
