Frequently Asked Questions
Everything you need to know about our handmade BioThane® gear, production timelines, shipping, care, sizing, and custom orders.
How do I care for my BioThane® gear? +
BioThane® is waterproof, odor-resistant, and easy to maintain. Most dirt wipes off with warm water and mild soap. For heavier messes, soak in diluted oxiclean (unscented), then rinse and dry thoroughly. We recommend avoiding prolonged exposure to strong DEET-based insect repellents, which may affect the coating over time.
What if my dog chews through an item? +
Our gear is designed for durability, but no product is chew-proof. Damage caused by chewing is not covered under warranty. If something happens unexpectedly, reach out — we’re always happy to review the situation and see what options may be available.
What is considered normal wear and tear? +
Normal wear includes cosmetic signs of use such as minor scuffs, scratches, fading, or coating wear on hardware over time. Black hardware may naturally show silver underneath with regular use — this is expected and cosmetic only. Wear from chewing, misuse, improper storage, or unsafe restraint is not covered.
How much is shipping and how long will my order take? +
Our production time for most orders is 2-3 weeks unless otherwise specified. Once shipped, delivery typically takes 1–5 business days depending on location. Shipping rates are calculated at checkout, with free shipping available on orders over $75. Need it sooner? We also offer expedited processing options when available.
How are your products packaged? +
Orders are packaged simply and intentionally to protect your gear while minimizing waste. We focus on practical packaging that gets your order safely to you — nothing excessive.
Do you offer returns or exchanges? +
Because most items are handmade to order, we generally do not accept returns on custom gear. If there is a sizing issue, please contact us — we’ll always do our best to help find a solution. If there is an issue with workmanship or a mistake on our end, we’ll make it right.
Can I cancel my order? +
Orders may be canceled within 24 hours of purchase. After that, production may already be underway and cancellations are no longer guaranteed.
Do you offer wholesale pricing? +
Yes. We work with select retailers, trainers, and partners who align with our brand and values. Contact us for more information about wholesale opportunities.
How do I choose the right size? +
Visit our sizing guide page to learn more about sizing. If you’re between sizes or unsure, reach out before ordering — we’re happy to help you choose the best fit for your dog.
Can BioThane® get wet? +
Yes — BioThane® is fully waterproof and made for muddy trails, rainy walks, dock diving, and everyday adventure. It won’t absorb water, hold odor, or stay soggy like traditional materials.

Contact Us →Excellent seller! Helped me match the leash to our rex specs. Took the leash out on a test hike as soon as it arrived. Quality is exceptional! Feels like it will hold up for a really long time. Roman is very happy to finally have some of his own gear in his theme color collected up. Will definitely be buying more stuff from you guys in the future! Thank you so much!
Thank you so much, Kristin! We’re glad we could help get the Professional Sewn Dog Leash just right for Roman, and it’s wonderful to hear he’s enjoying his new gear. We truly appreciate your support and look forward to making more for you both!
I ordered the professional series after having the hands free version, as I wanted something specifically for client meets, as well as just meets in general! I added my company name at the bottom, got the locking carabiners and overall couldn’t be more pleased. It looks nice, it feels amazing in the hands while handling the leash, and with the locking carabiner there’s extra peace of mind that my dog is fully secured to that leash. Might I add it’s easy to clean and in Washington state that is required to say the least
Thank you for your wonderful review! We are thrilled to hear that our Professional Sewn BioThane® Leash has exceeded your expectations and has been a versatile tool for your client meetings and everyday use. We take pride in our high-quality materials and locking carabiners for added security. It's great to know that you have also personalized your leash with your company name. We appreciate your support and we hope to continue providing you with top-notch products!
Went for the sewn biothane for extra peace of mind with my occasionally leash reactive rescue and added extra customizations. I had a good quality biothane leash from another company but it would get slippery, tangled easily, and wasn’t quite meeting my needs. This leash is far stronger and has the details I needed, but isn’t too heavy despite its thickness. I’ve had it for a few weeks now and far less slippery in the hand even when wet than my previous one. Hasn’t tangled at all. Super cute sea foam color too. I’ve recommended them to my sister for her service dog and will definitely order more myself when needed.
Customer service: Even though I had specific ideas for the placement of the traffic loop, slider, and o-ring and wasn’t sure if it was possible, Jake was extremely kind, detailed oriented, and responsive. He even responded to my online chat after 9 PM when I assumed I would get a response in the next few days and sent a follow up email to make sure he got everything perfect.
Quality! I’m really happy with my purchase.
The leash I ordered from bolder k9 has genuinely been life changing since I’ve received it. I use it on clients walks, for outings, everything. I can easily tether a dog somewhere or be hands free. The limits are endless and I’m genuinely going to order another one
Great

We've only used it a few times so I guess theoretically it could still fall apart and be a dud, but these leashes are wonderful. Incredibly high quality and perfect for our precious boy.

Just do it. It’s perfect.
Thank you so much, Tabitha! We love hearing that the Professional Sewn BioThane Leash was a perfect fit for you. We truly appreciate your support and kind enthusiasm.
Sturdy, nice material, pretty color, great hardware with the frog clip, and peace of mind that it won’t break.
Thank you so much, Joshua! We’re happy to hear the Professional Sewn BioThane Leash checked all the boxes for you and gives that extra peace of mind. We really appreciate you taking the time to share your experience.
Excellent quality. I keep coming back for all my dog’s leashes.
We got an all black leash with a carabiner clip and it’s beautiful. Sleek and sturdy. Customer service is also great. We asked if we could pay to add a traffic handle and they were happy make it happen! We love the hand sewn option. We don’t have to worry about my dog biting any metal when he’s carried his own leash, or getting hit with metal when he’s aggressively zooming around with his leash on. Lol.
Thank you for your kind words! We're thrilled to hear that you love your new Professional Sewn BioThane® Leash in all black with a carabiner clip. It's great to know that the hand sewn option provides peace of mind for your dog's safety. We're happy to have been able to accommodate your request for a traffic handle and that our customer service was able to make it happen. Thank you for choosing our product and for taking the time to leave a review!
Great quality biothane leash. A+
Strong enough for my Great Dane and soft enough on the hands if she pulls.
We love the new leash we bought for our GSD Scout. Jake was very helpful when it came to picking out the right leash. He had great recommendations from leash type to what kind of clip we should use. We ended up getting a BioThane 6ft leash and we love it.
Thank you so much for the great review, Kat! We love hearing you're happy with the Professional Sewn BioThane leash - we hope you get tons of use out of it with your pup!
Exactly what I was looking for. Color is beautiful. Thank you!
Thank you for the great review, Gina! We're so glad you love your new Professional Sewn BioThane Leash and we hope you get lots of great use out of it!
Spectacular product and customer service! I was looking for a biothane leash that didn’t have metal rivets and this sewn leash was perfect! I will definitely be returning for more biothane items.
