Using the Rogz Utility Step - In Dog Harness is a breeze. Just let your dog step into the harness. Then adjust the straps to fit your dog's body snugly but not too tight. Make sure the double metal ring attachments are secure before heading out for a walk. When it comes to maintenance, you can spot - clean the harness with a mild detergent and water. Keep it away from sharp objects to avoid damaging the webbing. After use, store it in a dry place. Also, regularly check the reflective stitching and the condition of the components. If you notice any signs of wear and tear, it might be time to replace the harness.
