To you, your dog's collar is just a minor accessory that serves a practical purpose: holding a name tag and a lead. To your dog, however, it is a constant companion that touches against their sensitive neck every waking moment of every day. When we consider the synthetic nature of nylon collars against the raw, regenerative properties of hemp, we are not just choosing between two pet accessories — we are choosing between two approaches.
1. The Hidden Dangers of Nylon
Nylon is a petroleum-based synthetic plastic that is very durable but comes with several hidden costs that pet owners do not realise until their dogs begin scratching at their collars.
-
Synthetic irritation: Nylon is commonly dyed using strong chemicals that are not good for your dog's skin. Studies have found that nylon collars can worsen symptoms in dogs that already have atopic dermatitis.
-
The "wet dog" smell: Nylon is not breathable, which means that if your dog enjoys a walk in the rain, their nylon collar is likely to stay damp — creating a mildew-prone environment that smells bad.
-
Abrasive texture: Nylon is not smooth against your dog's coat. Over time it saws at the fur, causing "collar baldness" or chafing. Many owners move from nylon to leather before discovering hemp — if you're weighing up those two first, our leather vs nylon collar guide is worth reading.
2. Why Hemp is the "Super-Fibre" of the Pet World
Hemp is not just a greener option — it is also superior to nylon in almost every regard.
Naturally Hypoallergenic & Antibacterial
Hemp is a natural fibre that is hypoallergenic by nature. It has natural antimicrobial properties that help prevent the growth of bacteria that cause skin infections. So if your dog gets wet, a hemp collar is less likely to develop the kind of bacteria that cause skin problems.
Strength That Rivals Steel
Do not be deceived by the natural look. Hemp is one of the strongest natural fibres on Earth. Hemp webbing resists over 500 lbs of force compared to a regular nylon collar at 250–400 lbs. Hemp also has natural resistance to UV rays, whereas nylon loses up to 40% of its strength after six months of sun exposure.
The "Jeans" Effect: It Gets Better with Age
Nylon starts soft but becomes frayed and scratchy. Hemp does the opposite. It softens with every wear. Much like a favourite pair of vintage jeans, a hemp collar breaks in and moulds to your dog's neck.
3. Sustainability: The Planet-First Choice
We cannot turn a blind eye to our plastic footprint in 2026. Hemp collars are the eco-friendly alternative to nylon.
| Feature | Nylon (synthetic) | Hemp (natural) |
|---|---|---|
| Source | Petroleum (fossil fuels) | Fast-growing Cannabis sativa plant |
| Biodegradability | Takes 30–40 years to break down | 100% biodegradable (5–6 months) |
| Carbon impact | High CO2 emissions | Carbon negative (absorbs 1.63 tons of CO2/acre) |
| Pesticides | N/A (lab-made) | Naturally pest-resistant |
4. How to Find the Perfect Fit
For your dog to be comfortable wearing a collar, the fit has to be right. A collar that is too tight puts pressure on the trachea, while one that is too loose is a safety hazard. Dogs that pull on the lead put particular strain on any collar — see our guide to stopping lead pulling for training and gear tips that reduce that pressure.
The 2-Finger Rule
-
Measure your dog's neck by wrapping a soft tape around the mid-neck area. Our full measuring guide has a breed-by-breed size chart.
-
Make sure you can fit two fingers between the tape and your dog's skin.
-
For hemp collars, if your dog is between sizes, go up a size. Hemp does not stretch the way nylon does, so this matters for comfort as the material softens. For dogs with airway sensitivities or those that pull regularly, a harness is often a better choice than any collar — see our harness buyer's guide for what to look for.

Frequently asked questions
Is hemp safe for dogs to wear as a collar?
Yes. Hemp fabric used in dog collars is made from the fibres of the Cannabis sativa plant and contains no THC — the psychoactive compound found in cannabis. It is completely safe for skin contact. Hemp collars are hypoallergenic and often recommended for dogs with skin sensitivities, as the natural fibre is less likely to cause irritation than synthetic materials.
How durable is a hemp dog collar compared to nylon?
Hemp is naturally one of the strongest plant fibres, making it surprisingly durable for collars. A well-made hemp collar can easily outlast cheap nylon options. High-grade hemp becomes softer with use while retaining tensile strength. However, for very large or powerful dogs (over 40 kg), a rolled leather or reinforced hemp collar may be a better long-term choice than standard-weight hemp.
Can hemp dog collars get wet?
Hemp handles moisture well — it absorbs water but dries quickly and does not hold odour the way nylon does. Unlike leather, hemp will not stiffen or crack after repeated wetting. For dogs who swim regularly, a hemp collar is a much better choice than leather. After swimming, simply wring it out and allow it to air dry naturally.
Are hemp collars better for dogs with skin allergies?
Often yes. Hemp is a natural fibre without the synthetic dyes and chemical finishes commonly found on nylon collars. Dogs with contact allergies or hot spots around the neck frequently improve when switched from nylon or polyester to natural-fibre collars like hemp or cotton. If your dog scratches at their collar or has a persistently irritated neck, a hemp collar is worth trying.
How do I clean a hemp dog collar?
Hemp collars can be hand washed with mild soap and warm water — scrub gently with a soft brush, rinse thoroughly, and hang to air dry. Most hemp collars are also machine washable on a gentle cycle inside a mesh laundry bag. Avoid bleach and harsh detergents, which can weaken the fibres over time. Hemp should never be tumble-dried on high heat.
