I’m fairly picky about leashes. I’ve probably gone through 10+ styles and looked through countless more at local pet shops. I have dogs who are small/medium sized but occasionally pull like wild horses. Most leashes have something “wrong” with them for my dogs - the clasps are too heavy for their size, the clasps are too dainty and likely to break under pressure, the leash is too thick/thin/delicate/ugly/imbalanced/etc. Mendota leashes are the only ones I’ve found that feel “just right” from the thin, but strong, colorful leash length to the lightweight but strong clasp. Finding all this in two leash sizes, both a 4 and 6 foot leash length was the cincher for me (as the vast majority of 4 foot leashes are absolutely hideous). The 4 feet length leash was our default when we lived in midtown Manhattan. We’ve since moved to suburbia so they’ve been upgraded to 6 feet, but I still have the 4 foot leash handy and highly recommend it as a back-up/secondary leash for everyone occasionally lets their dog tag along to high traffic areas
