You should fit two fingers under any properly adjusted strap. For harnesses, also measure chest girth at the widest point behind the front legs. Between sizes? Choose the larger size and fine-tune with the adjustable straps. Care & Maintenance Inspect straps and stitching monthly for early signs of wear. Hand wash with mild soap and air dry to preserve webbing and stitching. Rinse after beach or pool trips to remove salt and chlorine. Store flat or hung rather than crumpled to keep shapes crisp.
