How to Customize Your Leash
Step 1: Pick Your Hardware
-
Solid Brass – Rust-proof and durable, with a classic look.
-
Sport (Autolocking Carabiner) – Lightweight, strong, and secure, with a modern look.
Step 2: Pick Your Size
Width:
-
Small (3/8") – Best for dogs under 30 lbs
-
Medium (1/2") – Best for dogs 30-60 lbs
-
Large (3/4") – Best for dogs over 60 lbs
Note: These are comfort guidelines, NOT safety ratings. BioThane® is incredibly strong and an undamaged line will not break even with the most determined pulling. Longer lines naturally become heavier. For better handling and ease of use, choose a thinner width as length increases.
Length:
-
4 to 6 ft – Best for close control in crowded or tight spaces.
6 ft = conventional "standard" leash length -
8 to 12 ft – Perfect as an all-purpose, everyday leash
10 ft = bestselling everyday leash -
15 to 20 ft – Ideal for hikes, beach trips, camping, travel, and training
15 ft = ideal hiking leash
20 ft = versatile adventure + training leash -
30 to 50 ft – Best for open fields, quiet beaches, SniffSpots, or backyards.
30 ft = great for intermediate/advanced long line users
Step 3: Pick Your Colors
-
Single Color or Two Tone - Two tone leashes have an accent color at the clip and handle ends.
Most popular color combos:
Sage + Forest Green
Black + Caramel
Ocean + Midnight
Poppy + Plum
Green Apple + Blueberry
Lavender + Violet
Step 4: Choose Your Handle
-
Standard Loop Handle - default selection

Convertible Handle + Sliding O-Ring – For hands-free use; our most popular customization!

Recently adopted my sweet girl who was trained on a retractable and she's adjusted beautifully to the new leash! It's better for me too as I have more control and she keeps her sniffing freedom! I also ordered it in green apple as the primary color and it's easy for both of us to see, even at night! It's easy to clean and soft on my hands. The clip is just the right size for my little pup (only 8lbs!) and the 2ft traffic handle is always within easy reach ♥️
Oh my goodness, such sweetness she is! Thank you Sarah, we are so glad you are both loving your HTH gear (and freedom!)
The leash looks great. The locking caribener seems very secure. My husband doesn't like the way it feels in his hand (we have the thinner leash). Unfortunately after using this leash for about a week, my 6 month old puppy was lying at my husband's feet and bit the leash in half. Her adult teeth have been coming in and she's been chewing more than usual. Obviously not high tail's fault but it's hard to leave 5 stars for something that broke so quick. I would not recommend this for dogs that grab the leash or chew.
