Five Tips for Getting Started Using a BioThane Long Line

A BioThane long line is one of the most versatile pieces of gear you can have for your dog. Whether you're using it for enrichment walks, training, hiking, or recall practice, a long line allows your pup more freedom while keeping them safe and connected.

However, handling a long dog leash takes some practice! Here are five essential tips to help you get started with confidence.

1. Choose the Right Length

Getting Started: If you're new to the world of long lines, we recommend starting with a leash that is just a few feet longer that what you are currently using. For most of us used to handling standard 6 foot leash, upgrading to 10 or 12 foot long line is a great starting point! 

✔ Shorter long lines (8-12 ft): Great for neighborhood walks, slow sniffy walks, small dogs and senior dogs, or as an all purpose everyday leash. 

✔ Mid-length (15-20 ft): Perfect for decompression walks, hikes, beach trips, recall training, traveling, and more - an awesomely versatile adventure leash! 

✔ Longer lines (30-50 ft): Best for wide-open spaces, big backyard, SniffSpots, or uncrowded open fields. Requires intermediate to advanced long line handling skills. We don't recommend this for beginners. 

💡 Remember that just a few extra feet of leash makes a big difference! We know that making your selections can be hard. When starting out - start simple. We recommend a Small or Medium Standard 10 foot Leash as an amazing "gateway" long line. Check out more tips on Long Line Sizing and Customizing Your Long Leash.

2. Choose the Right Gear

Using a long line changes how you handle a leash, so having the right setup is key!

✔ Flat Collar with ID Tags – Always keep a form of ID on your dog.
✔ Back-Clip Harness – Prevents legs from getting tangled and reduces risk of neck injury. We do NOT recommend clipping a long line to your dog's flat collar. 
✔ Long Line – Waterproof, stink-proof, and lightweight for easy handling. 

💡 Add-on accessories for extra safety and convenience:

✅ Safety Strap – Attaches from the harness to the collar or leash base to the collar, preventing accidental escapes.
✅ Built-in or Stand Alone Traffic Handle – Helps quickly secure your dog when needed. A built in Traffic Handle is available for products in our Custom Leash Collection. 
✅ Waist to Leash Strap – Keeps the leash attached to you even if you drop it.
✅ Quick Release Long Line Keeper – Keeps your long line neatly stored and tangle-free.

3. Learn and Practice a Safe Leash Grip

Unlike a short leash, long line handling is dynamic—you’ll need to actively manage giving and taking slack.

💡 Try the “Thumb Grip” (aka Ice Cream Cone Grip):
✔ Hold the leash between your thumb and index finger with the dog-end on the outside of your thumb.
✔ Let the line slide through your hand as needed.
✔ If you need to stop the line, close your fist—this acts as a natural “brake” without causing leash burn, and it allows you to drop or release the line if needed without risking injury to your fingers or thumb. 

The Thumb Grip is a safe and effective way to hold a long line. In this photo I am holding a leash with no handle, but this grip can be used anywhere along the length of a leash, not just at the end. 

4. Practice Skills at Home First

Before heading out into the world with a long dog leash, take time to practice at home. Handling a long line is different from a standard leash, and mastering the mechanics first will help both you and your dog have a smoother experience.

Start with Proper Grip & Handling

Begin by using the thumb grip, holding the leash in your non-dominant hand while your dominant hand adjusts slack, slows the leash, or acts as a brake when needed. This grip prevents leash burn and allows for better control. For added stability, use both hands—one holding the leash material and the other grasping from the top to manage slack and apply gentle braking. If you're using a longer leash (12+ feet), keeping both hands engaged will help prevent tangling and maintain control.

Practice in a Low-Distraction Environment

Once you’re comfortable with leash mechanics, practice in a quiet space like your backyard or an open field. Avoid areas with triggers (dogs, squirrels, busy sidewalks) until you feel confident handling the leash. Give yourself time to get comfortable before heading into higher-distraction areas.

Keep a “Smile” in the Leash

One of the biggest advantages of a long dog leash is reducing leash tension so your dog can move naturally.

✔ Avoid tension or dragging excess slack—aim for a gentle “smile” shape in the leash.
✔ Regularly adjust slack as you walk, keeping the leash just above the ground.
✔ Practice leash handling at home first—it takes time to get used to managing a balanced line!

When you’re ready to transition to busier areas, stay engaged with your dog, anticipate movements, and adjust slack as needed. The more comfortable you are with leash handling, the more enjoyable and safe your walks will be!

5. Maintain Situational Awareness

Safety comes first! Before heading out, always:

✔ Check local leash laws—some areas require 6 foot leashes.
✔ Choose open spaces for practice—start in low-traffic areas before using it on busy trails. For lots of ideas, Check out our blog post 20 places to take your dog for an enrichment outing.
✔ Manage slack carefully—gather the leash when approaching corners, crossings, or tight spaces, or when around others. 
✔ Scan your surroundings—anticipate distractions like wildlife, bikes, or other dogs.
✔Always be aware of where your long line is to avoid tripping others, causing leash burn, or causing injury to your dog. Be conservative. When in doubt, gather up slack and move away. 

💡 Pro Tip: If your dog is reactive or easily distracted, work with a force-free positive reinforcement trainer to build skills gradually.

Ready to Go Longer?

Once you’re comfortable with a 10-12 foot long line, you may want to explore a longer leash (20-50 feet) for training, hiking, or sniffari-style outings.
