How to Customize Your Leash

Step 1: Pick Your Hardware

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!

  • No Handle / Drag Line – Reduces snagging; ideal for off leash or off trail hikes.

  • Add specialized hardware like a D Ring or O Ring to your leash handle.

Step 5: Add an Optional Built-in Traffic Handle for more control when you need it:

  • At base of leash

  • 12" above leash clip (most popular)

  • 18" above leash clip

  • 24" above leash clip

  • Custom placement (Leave a note at checkout)

Drag or connect!

We let the leash drag on hikes or connected on a jog. Never a hitch and easy to clean.

So glad you're enjoying your new HTH gear! Thank you Robin!
