Both materials do the job; they just age differently and suit different dogs. Here is the honest comparison, without pretending one is always better.

Nylon: the practical default

Nylon is light, dries fast, wipes clean, and costs less. It takes bright colors and prints well, and it shrugs off swimming, mud, and rain. Its weaknesses: it frays over years, holds odor if never washed, and cheap webbing can rub sensitive skin. For active, wet, muddy dogs, nylon wins on maintenance alone.

Leather: the long-game material

Good leather outlasts several nylon collars, softens as it breaks in, and tends to be kinder to dogs whose coat rubs thin under webbing. The trade-offs: heavier, slower to dry, needs occasional conditioning, and costs more upfront. For strong dogs on daily leash duty, a leather lead is also easier on your hands.

Quick decision guide

• Swims or plays in rain often: nylon.
• Strong puller, daily long walks: leather lead for grip comfort.
• Sensitive or thin coat: soft leather or padded nylon.
• Budget and colors first: nylon.
• One purchase for years: leather.

Whichever you pick

Check the hardware, not just the strap: the buckle and D-ring fail before the material does. Solid metal fittings are worth more than any material label.
