Frequently Asked Questions
We offer a range of Biothane dog walking and training accessories including Traffic handles, safety straps, long line keepers, clicker straps, utility belts, keychains, and more. We also offer non-BioThane walking accessories like poop bags and waste bag holders, all designed to pair seamlessly with our BioThane® gear.
Yes! Our BioThane® accessories are made with solid brass or Sport (carabiners made from aircraft grade aluminum paired with and black steel) hardware. All are water proof, odor proof, and easy to clean.
Most accessories clip to a leash D‑ring or can be attached via a carabiner to our Utility Belt or your own waist belt. Some items (like leash keepers or traffic handles) are intended for specific products; see each product page for instructions.
Soak in warm soapy water, clean with a towel or sponge, and rinse with water. For tough messes, a light scrub with a soft sponge or toothbrush works well. Always store dry. Solid brass will not rust, but may develop a natural patina over time. Black‑coated hardware may show cosmetic wear or rust over time, but strength isn’t compromised.
Our BioThane® accessories are available in our full range of colors; perfect for matching your other walking gear. Many of our accessories have custom width and length options to fit you and your dog.

I recently upgraded my leash and added a safety strap to my order. My girl, Mandy wears a harness but she is still learning not to pull so much. She is making progress but if she sees something of great interest (squirrel etc), she will jerk the leash very hard. I have always been concerned that if she doesn't rip my shoulder out of socket she might break the harness and be free to chase her furry friend. When I saw this safety strap I was so excited to add this to our tool box. Now I know she will be safely attached to her collar if the harness were to fail. This is a great addition to our Biothane leashes. I was able to get it in matching colors and I love the hardware.
That is great! I'm sure your Mandy will be doing better and better! Thank you Eileen, we love the photos too!
This is a great little safety strap. I haven't tested it out yet as I live overseas and it took me a while to actually get my hands on it after ordering, but now I've seen it, the design looks very robust for a lightweight item. The carabiners are quick and easy to use and should be pretty well failure-proof (which is one of the great benefits of gear that has been derived from the climbing industry). I love the colour too!
Thank you Catherine! We hope you have many amazing adventures with your HTH gear!
