Biothane is the better choice for dogs that swim, get muddy or tend to smell, because it's waterproof, odour-resistant and wipes clean in seconds. A nylon or fabric collar is lighter, softer and comes in more patterns, which makes it a good fit for everyday dry use. This guide breaks down the real differences so you can pick the right one for your dog and your climate.
What is biothane?
Biothane is webbing — a strong polyester core — sealed in a waterproof coating. That coating is what gives it its standout qualities: it doesn't absorb water, doesn't hold odour, won't fray, and resists UV, mud and mildew. It feels a little like soft leather but needs none of the upkeep, which is why it's popular for active dogs and wet climates.
What is a nylon or fabric collar?
A nylon collar is woven fabric webbing. It's lightweight, soft against the coat, inexpensive and available in the widest range of colours and patterns. The trade-off is that fabric absorbs water, so it can get heavy when wet, dries slowly, and may trap odour or mildew if it isn't dried properly after rain or swimming.
Biothane vs nylon: the differences at a glance
| Feature | Biothane | Nylon / fabric |
|---|---|---|
| Waterproof | Yes — doesn't absorb water | No — soaks up water |
| Odour | Stays odour-free | Can trap smells when wet |
| Cleaning | Wipe or rinse, dries instantly | Needs washing, slow to dry |
| Durability | Won't fray, rot or mildew | Can fray over time |
| Weight | Slightly heavier in thicker widths | Light |
| Look & patterns | Clean, solid colours | Widest range of patterns |
When to choose biothane
Choose biothane if your dog's lifestyle involves water or mess, or if you simply want a low-maintenance collar. It's the right pick when your dog:
- swims, or you walk near water, beaches or rivers;
- loves muddy fields and wet-weather walks;
- tends to develop a "doggy" smell on fabric gear;
- hikes or spends long days outdoors;
- lives somewhere with a lot of rain.

When to choose a fabric or martingale collar
A fabric collar makes sense when looks and lightness matter more than waterproofing — for everyday dry walks, indoor wear, small or delicate dogs, or when you want a specific pattern. For sighthounds, the fabric martingale collars also give the limited-slip security those breeds need; if you're unsure of the fit, see our martingale sizing guide.
How to clean each type
Biothane is the easiest collar to clean: wipe it with a damp cloth, or rinse under water with a drop of mild soap, then it's dry almost immediately. A nylon collar should be hand-washed or machine-washed in a bag with mild detergent, then fully air-dried — putting a damp fabric collar back on is what causes odour and skin irritation.
Is biothane good for sighthounds?
Yes. Biothane suits sighthounds well, and a thinner width sits comfortably on their slim necks. For greyhounds and whippets it pairs naturally with a martingale style, giving you secure, escape-proof control with none of the upkeep of fabric — ideal for dogs that walk in all weather.
Frequently asked questions
Is biothane better than nylon for dog collars?
It depends on use. Biothane is waterproof, odour-resistant and wipes clean, which makes it better for dogs that swim, get muddy or smell. Nylon is lighter, softer and comes in more patterns, which suits everyday dry use.

How do you clean a biothane collar?
Wipe it with a damp cloth, or rinse under water with a little mild soap, then it dries almost instantly. Unlike nylon it doesn't need machine washing and won't stay damp or smelly.
Does biothane smell or hold odour?
No. The coating doesn't absorb moisture, so biothane stays odour-free even on dogs that swim or roll in things, unlike fabric collars that can trap smells.
Is biothane good for sighthounds?
Yes. Biothane suits sighthounds well and pairs with a martingale style for secure, low-maintenance everyday wear.
