Why we love the Trainer

The adjustable handle opens a world of peaceful possibility

The Trainer aids you and your dog into off-leash confidence — this long line is designed to adapt as your dog masters recall. Or, if your dog is simply not a candidate for off-leash life, then give them the experience of it while remaining securely attached to you.

Clip the line to your dog and adjust the handle at the other end to suit your needs: open it wide to wear it across your chest and free your hands to work with the line, adjust it into a traditional handle, or close the handle all together when you're ready to fully drop the lead, so the line won't catch on paws or bushes as your dog explores.

The Trainer is also a mindfulness tool — wear it cross-body wearable and immerse yourself in the moment with your pup on a sniffari. We love the double finger lock method to securely and intuitively manage the line. This hands-on approach enhances your bond and helps you de-stress from daily life, including from the doom-scroll device in your pocket.

The Trainer features an auto-lock carabiner, so you can depend on it staying attached to your dog, and is made of BioThane, a durable material renowned for its waterproof, stink-proof and easy to clean properites making it the best choice for product designed to drag

Choose the 15 ft length for urban and wooded walks or 30 ft for open spaces. Custom lengths available – contact us!

Never leave dogs unattended while wearing TinyHorse gear.

Ensure that clips have properly locked when connecting to a dog. Regularly clean and inspect mechanisms to ensure they are functioning properly.

Close handle loop entirely before dropping the line on the ground. Handles, loops and hardware at the end of long lines pose serious danger to your dog's limbs. We've gone to great lengths to ensure our long lines are safe for dragging.

If you've dropped the line, regularly recall your dog and have them check in.

While we've made the safest choices possible for this product, animals are unpredictable by nature. Furthermore, choices made in regards to how animals are handled and how the quality of the gear is maintained in the long term is not within TinyHorse's control. By purchasing this product, the customer hereby releases TinyHorse from any liability or responsibility that may occur, either indirectly or directly from the use of this product.

Please email us immediately at if you experience a safety incident as a direct result of this product.



🫧 Light cleaning: wipe long line with a warm, soapy cloth then hang to dry.

🧽 Deep cleaning: soak long line in warm soapy water for 30 mins, wipe with a cloth then rinse thoroughly. Hang to dry.

🧺 Machine wash: Put long line in a laundry bag, wash on gentle with cold water, hang to dry.

🧼 We recommend using mild detergents as heavy duty detergents have shown to effect the finish on some products. If you are unsure of the intensity of your detergent and want to extend the finish, soak clips in hot water only.

🌊 Rinse product after exposure to salt water.


🛠️ Ensure that you regularly soak the entire product. It's important to clear debris from the mechanics of clips for long-term use. Apply high-quality oil to swivel to extend the life of your long line - like a tire tread, this mechanism eventually wears away and the long line will need to be replaced. NEVER apply oil to locking mechanisms as this may lead to unwanted unclippings. Regularly check the swivel and opening/closing mechanism of clips.

🦷 Never leave your gear unattended with dogs known to chew.

🚗 Do your best to protect gear from exposure to extreme conditions, especially those created during vehicle storage (such as direct light through windows or freezing temperatures).
