The Pawzly Harness & Interchangeable cover system was created so that you can easily and affordably give your best furry friend a new awesome look every day of the week. All that's needed to start is the base harness (this listing), and you're ready to start collecting from our huge selection of interchangeable and reversible covers. Be sure to check out our storefront for a wide range of covers before checking out! This is the base harness that all of our covers can be buttoned on to for a new look every day. Featuring a thick nylon webbing strap and D-ring for attachment to a leash, two hook & loop straps for securing around the neck and midsection, and an additional snap lock around the neck (except for sizes XXS and XS). Please note that unlike our covers, the harness is not reversible. The XL and XXL harnesses share the same harness shape, the only difference being the length of the strapping used around the neck and girth of your dog. The XXL harness includes extra strapping, with the intention that you will cut it down to size once you've sized your dog appropriately. The excess strapping can be cut off, and the edge can be melted gently with a flame to prevent unraveling. All harnesses include a free 'I ♥ My Dog' charm! We recommend using an additional collar for any dogs over 15 lbs, or excessive pullers. While we use industrial strength hook & loop fasteners to keep your pup safe and secure, our harnesses are intended for style over function.
