Loving our new leash

I have always love biothane leash because of its ease to clean and all the colors. I tried a longer length this time with the gorgeous sage color (my current fav). I like it. It gives my pup a bit more freedom and she seems to like it too.

Thank you Jennifer! We wish you (both) many happy trails!

Light weight long line

Love the skinny long lines for my small pups. Great colors.

Thank you Kim!

I went back to buy another

I have two of these in the 6 ft length with brass scissor snaps. One has the D ring at the base of the handle and I find it very useful for carrying used waste bags. I also have a 12 ft sport convertible leash that I love. I’d like to see a purple that’s between violet and lavender, more of a royal purple. Also, the brass hardware doesnt match all the silver-covered metal on my dog’s harnesses but that’s just personal pickiness. It didn’t keep me from ordering two lol

I love the purples too! Thank you for your review Rachel! So glad you're loving both of your HTH long lines!

Whitney G.

It was time for a new long line after a few years of constant use. I like the 20 foot length to use for swimming at the lake and trails at my neighbors. My German Shepherd's love the extra length and room to explore and sniff. The leashes are lightweight and easy to hold when walking two dogs. And easy to clean off the sand and dirt. I plan on getting 8 foot ones for in town and parks when it warms up in the spring.

My favorite is the ease of cleaning too! Thank you Whitney for your love of HTH gear! Happy Tails to you and your GS!

I love that these leashes

I love that these leashes are lightweight, supple, resist knots and tangles and are easy to clean. I usually use a 6 foot leash but decided to go up to 8 feet for local walks and 10 feet for hiking. My little gal is not much of a puller, but now with longer leashes she pulls even less. She also gets more room for sniffing and exploring. I even tried the 10 foot on my 70 pound dog and it's so strong I think I'll be getting him a 15 foot in 3/8 inch for hiking as it will be more lightweight than the 1/2 inch

We are so happy to hear you are loving your new longer lines! Happy Trails, Thank you Maria!
