Carnival Step-in harnessThis is one of the safest and easiest to use harnesses! How to use it:Firstly place the harness onto the floor so that your little treasure can place a front paw through each leg opening. Secondly, pull the buckle ends up over the shoulders and, finally, fasten it. Please note that when adjusted properly, the rib strap is snug (so your pet can't back out), and the chest strap is comfortable but not loose. This harness is designed to pressure the breastbone and rib cage. We recommend to attach the swivel hook of your Leash through Both D-rings at the shoulders. Removing the step-in harness is just as easy as putting it on. Release the buckle at the shoulders and drop it to the floor. Your pet can just step away freely. This harness is soft and comfortable and is adjustable in sizes and prints.
