I have two custom made 5’ biothane leashes, one is olive/gold and the other is brown/gold. They’re beautifully made, but my dog hates it, I think they’re just a little too heavy for her 15 lb body. Would recommend for a 30 lb - 50 lb dog. The Olive one was never used, the brown one has been on 5 short walks and is basically brand new still. Bjothane is... • Waterproof • Odorproof • Easy to clean • Durable • Stylish • Strong From the original seller: “Biothane is a very strong and durable material. Leashes are made with 5/8" wide, super heavy biothane at .150" thick. It has a breaking strength of over 600 lbs while most of the hardware has a breaking strength of 350 lbs or more. The hardware is solid brass.” Not with tags since none came with.
