Salty's Own is a family business (and Etsy store) I recently discovered that makes nautical-inspired dog leashes tied by hand in New England using US-made paracord and with solid brass clips. I love their backstory:

While serving in the US Coast Guard, my great uncle tied beautiful leashes for our family dogs. My daughter and I have revived that family tradition. Our leashes are tied by hand in New England with the finest materials. We hope you and your dog enjoy your time together!

They offer a variety of lengths and colorways to choose from, along with specialty creations like these:

• The "Destination" collection is inspired by the family's favorite places, such as the USA (pictured in the hero image above), Nantucket, Santa Fe (Etsy-only as of this writing), and Martha's Vineyard. ($39–$42)
• Their "float" leash is made from floating marine line, making it easy to grab if your dog likes to swim. Not to be used as a floatation device. ($32)

You can browse the Salty's Own online store or see what they have available on Etsy.
