All Lottie & Co dog harnesses are fully adjustable with adjustable neck and back straps. They have a quality, black D ring buckle on the back for secure lead attachment. Our dog harnesses are made out of high-quality tweed and corduroy, with internal mesh for your dog’s comfort and breathability while on your walkies. We always recommend hand washing our products, in order to maintain the quality of the fabric. For more information, head to our product care page.
