You’ve washed it. You’ve left it in the sun. You’ve even tried baking soda. But no matter what you do, your dog’s collar still smells. Sound familiar?
The problem isn’t your dog — it’s the material. Most dog collars are made from nylon or leather, and both have a fundamental design flaw: they absorb moisture. Once moisture gets in, bacteria follow. And bacteria is what causes that unmistakable wet-dog smell that no amount of washing seems to fix permanently.
In this post, we’ll break down exactly why collars smell, which materials are the real culprits, and why a growing number of dog owners are switching to coated webbing as the permanent odor-proof solution.
Why Dog Collars Smell in the First Place
Your dog’s collar sits against their skin all day, every day. It absorbs sweat, natural skin oils, mud, rainwater, and whatever your dog decides to roll in. For most collar materials, this moisture soaks straight in — and once it’s inside the fibers, it creates the perfect warm, damp environment for bacteria to multiply.
The smell you notice isn’t actually the water itself — it’s the waste products produced by those bacteria as they break down organic matter trapped in the collar material. Washing removes some of it, but unless the collar dries completely and quickly, the bacteria simply regrow.
This is why collars that look clean can still smell. The bacteria are deep inside the fibers, not on the surface.
The Worst Offenders: Nylon and Leather
Nylon is the most common collar material — cheap, lightweight, and available in every color. But nylon is essentially a woven fabric, and fabric absorbs liquid. After a few wet walks, the fibers are saturated with moisture and organic debris. Washing helps temporarily, but nylon takes a long time to dry fully, and in the meantime, bacteria are thriving.
Leather is the premium alternative, but it has its own problems. It’s porous by nature, which means it absorbs water, sweat, and oils over time. Wet leather smells — and as it dries out, it can crack and degrade. Leather collars also require regular conditioning to stay intact.
Both materials share the same core problem: they’re porous. And porous materials trap bacteria.
What Is Coated Webbing — And Why Doesn’t It Smell?
Coated webbing is a material originally developed for industrial and outdoor applications — think horse tack, marine equipment, and working dog gear. It’s made from a strong nylon or polyester core that’s bonded with a smooth PVC outer coating.
That outer coating is the key. Unlike nylon fabric or leather, the surface of coated webbing is completely non-porous — which means water, mud, sweat, and bacteria have nowhere to go. They sit on the surface rather than soaking in, and can be wiped away in seconds with a damp cloth.
No absorption. No bacteria build-up. No smell.
This is the same principle behind BioThane®, the gold standard in premium waterproof dog gear. BioThane-style coated webbing products offer the same core benefits — a smooth, sealed surface that repels moisture and resists odor — at a more accessible price point.
“The look and feel of leather — without the upkeep. Wipe it down after a muddy walk and it’s done.”

Which Dogs Benefit Most From an Odor-Proof Collar?
Honestly? All dogs benefit. But coated webbing collars are especially worth it if your dog:
- Loves swimming — Lakes, beaches, and puddles are no match for a non-porous surface.
- Gets walked in rain regularly — No more soggy, heavy collars that take hours to dry.
- Has sensitive skin — Bacteria build-up in wet nylon can irritate skin. Coated webbing stays clean.
- Wears their collar 24/7 — If it never comes off, it needs to stay hygienic on its own.
- Loves rolling in things — The smooth surface means mud and mess wipe right off.
How to Clean a Coated Webbing Collar
This is the part most coated webbing owners find almost unbelievably simple:
- Wipe the collar with a damp cloth.
- Done.
For a deeper clean after a particularly muddy adventure, mild soap and water works perfectly. The collar dries in minutes because the water-repellent surface doesn’t absorb moisture. No machine washing, no air-drying for hours, no conditioning required.

Frequently Asked Questions
Is coated webbing safe for my dog’s skin?
Yes. The smooth, non-porous surface is gentle on skin and doesn’t cause the chafing or irritation that rough nylon weave can. It’s also antibacterial, which means it won’t harbor the bacteria that cause skin irritation in sensitive dogs.
Will a coated webbing collar get stiff in cold weather?
No. Unlike leather, which can stiffen and crack in cold temperatures, coated webbing remains flexible year-round. It’s designed for outdoor use in all conditions.
How long does a coated webbing collar last?
Significantly longer than nylon or leather alternatives. Because it doesn’t absorb moisture, it doesn’t degrade from the inside out the way porous materials do. With basic care, a quality coated webbing collar should last several years of daily use.
What’s the difference between BioThane® and BioThane-style coated webbing?
BioThane® is a registered brand name for coated webbing made by BioThane Coated Webbing Corp in the USA. BioThane-style coated webbing uses the same construction method — a strong inner core bonded with a smooth outer coating — but is not produced by that specific manufacturer. The core benefits (waterproof, odor-proof, easy to clean) are the same.
