Match the setting
Busy sidewalks, trails and open areas create different handling needs.
Inspect clips and stitching
Hardware and attachment points carry repeated load.
Weather matters
Snow, salt, rain and mud can affect grip, drying and corrosion resistance.
Avoid universal length claims
Local rules and the dog's handling needs matter more than one fixed number.
