Description
Mini BioThane Safety Connector
Backup Leash Attachment for Added Security
The Mini BioThane Safety Connector is a simple but essential piece of safety gear designed to provide peace of mind when using prong collars, martingales, or harnesses as your primary leash attachment. Acting as a secondary connection, this safety connector clips from your leash to your dog’s flat collar, helping reduce the risk of accidental escapes if primary gear fails.
Compact, lightweight, and unobtrusive, it’s an easy add-on that adds a critical layer of protection during everyday walks and training.
Beyond the Donation

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.

I got nervous every time we were out that they would lose their expensive ecollars while sticking their heads out the window in the car or hiking in the woods. I used to use a carabiner but a durable one was bulky around their necks. These mini connectors are 7 inches, lightweight and durable. I use it to connect the ecollar with the regular collar. It's the perfect size, waterproof and looks so good on them! I don't have to worry about losing their ecollars anymore woohoo 🥳 Highly recommend this product!
Thank you for your positive review! We are glad to hear that our Mini Safety Connector has helped ease your worries while adventuring with your dogs. We take pride in providing durable and lightweight products that make pet owners' lives easier. Thank you for recommending our product. Happy adventuring!
I love the quality of our safety connector so much that I will be purchasing a leash soon down the road. The thickness is great. Customer service is super kind and my package made it on time even while Hurricane Milton was going on here in Florida! Love the spooky packaging too! Thank you!
Exactly what I needed. Thank you!
Great quality materials and fantastic craftsmanship! Very simple to use and easy to unhook when no longer needed.
My sister and I are both service dog user. She has bought a few thing form others biothane makers and the quality has not been the same. I am definitely super happy and delighted by the quality and craftsmanship even thought the piece is small it is the difference is huge. I’ve put off buying a connector for her pinch collar for a while. But I am glad I chose this company. Will definitely shop here again.
Awesome little clip for my dog’s prong collar, makes me feel much more secure walking her on her prong especially after using it over the 4th of July. Love that I was able to get it in her color too! Great quality!
Accidentally ordered in a color they don’t advertise, but they were awesome when I messaged them to correct it. Item is impressive quality, feels sturdy and well made. I would definitely buy again, and will buy again in the future!
quality is fantastic!! as well as very responding to any questions or concerns i had, my dog is wearing the biothane leash along with the collar connector
Definitely worth getting. Much more durable and super high quality than the basic nylon ones off amazon.
Thanks so much, Chris! We're thrilled to hear the Mini BioThane Safety Connector exceeded your expectations and stood out compared to other options you've tried. We truly appreciate your support and hope it gives you lasting confidence every time you're out with your pup.
Love these, I’ve ordered several and they are all very well made and sturdy while still being short and low profile enough for my needs.
We really appreciate your continued support, Gigi! It's wonderful to hear the Mini BioThane Safety Connector has been a great fit for your needs and that you've been happy enough to come back for several. Thanks again for taking the time to share your experience!
Perfect length safety strap to connect my pup’s prong to his flat collar!! The teal and black was a great addition to his gear collection!
Thanks so much for your review! I’m so glad the Mini BioThane Safety Connector was the perfect length for adding extra backup between your pup’s prong and flat collar, and that the teal and black combo matched the rest of the gear so well. It truly means a lot to hear the handmade dog safety connector feels functional and looks great too — I really appreciate your support!
I love the safety connector. After a few escapes from his harness, I knew I had to do something to keep my mini doodle safe. This connector puts my mind at ease, know that if he escapes from his harness again, he will still be connected to his collar and he will not be able to run off. The connector is very well made, and looks good too!
Thanks so much for your thoughtful review! I’m so glad the Mini BioThane Safety Connector is giving you extra peace of mind after those harness escapes and helping keep your mini doodle safe on walks. It truly means a lot to hear the handmade dog safety connector feels secure, well made, and gives you confidence knowing your pup stays connected if a harness slips free — I really appreciate your support!
