Best long dog leash?

Hey all,

I’m looking for a long leash for Cooper. He’s 5 and has pretty good recall, but he’s a little nervous in new places, so I like having him on a long leash when we’re out and about to give him some freedom but still lets me keep an eye on him. I’m hoping to find something that’s sturdy but not too heavy, since he can get a bit overwhelmed with anything too thick or bulky.

Would love to hear what’s worked for you!

Thanks!
