Single-Coated vs Double-Coated Pet Fur: How to Tell Which One Your Pet Has (and Why It Matters for Chiengora)
If you have ever looked at your pet's fur and thought "Is mine suitable?", you are in very good company. It is the question we get asked most about Chiengora (spinning pet fur into yarn), and the honest answer almost always starts with: "It depends on the coat."
Here on the farm we spend our days with sheep fleece, so we are slightly obsessed with fibre structure. Pet fur has just as much going on as wool does. Whether your pet is single or double coated changes how the fur spins, how the finished yarn feels, and what that yarn is best used for.
Our breed list and photo examples on the website are a great starting point, but we know a list doesn't help much if you have a rescue mutt, a fluffy mixed breed, or a cat of mysterious ancestry. So this post goes a step further and shows you how to work it out for yourself, with nothing fancier than your fingers and a brush.
You can always check our double-coated breed list and photo examples on the pet fur spinning page alongside this page.
First, the Basics: Topcoat and Undercoat
Most animal coats are made of two kinds of hair.
The topcoat (guard hairs)
The topcoat is the outer layer. These are the long, straighter, coarser hairs you see and stroke on the surface. They are also called guard hairs or primary hairs. Their job is to shed water, block dirt and protect the skin from sun and scratches.
The undercoat
The undercoat sits underneath. It is short, soft, fine and dense, and often a bit woolly or fluffy in texture. Its job is insulation, keeping your pet warm in winter and (surprisingly) helping regulate temperature in summer too.
If you have ever handled sheep's wool, think of the undercoat as the "wool" and the topcoat as the tougher outer hair.
Double-Coated vs Single-Coated: What's the Difference?
Double-coated pets have both layers: a coarser topcoat over a dense, soft undercoat. Think of a husky, a Pomeranian or a Maine Coon.
Single-coated pets have just the topcoat layer, with little to no undercoat. Their fur is often silkier, finer or curlier, and it tends to feel the same all the way down to the skin.
Neither is better or worse as a pet, of course. They are just different, and that difference matters a lot once fur meets a spinning wheel.
How to Check Your Pet's Coat at Home
You don't need special equipment. Try a few of these checks together, because no single test is perfect.
1. Part the fur and look underneath
This is the big one. Use your fingers to part the fur on your pet's side or back, down towards the skin.
• Double coat: You will see a second layer of shorter, fluffier, denser fur underneath the longer outer hairs. It often looks a different colour or texture to the topcoat, and may feel like cotton wool or down.
• Single coat: You will see one length and type of hair, straight through to the skin. You can usually see the skin quite easily.
2. Feel the texture
Run your fingers through the coat. A double coat often feels plush and springy, with a "two textures" feeling: smooth guard hairs on top, a woolly cushion underneath. A single coat tends to feel uniform, whether that is silky, wiry or curly.
3. Watch how it sheds
Double-coated pets typically "blow coat" once or twice a year, usually in spring and autumn. Fur comes out in clumps and tufts, and you may be vacuuming fluff for weeks. Single-coated pets shed too, but it tends to be steady, individual hairs rather than seasonal fluff-storms.
4. See what the brush brings out
A slicker brush or undercoat rake is a great test. If you brush and pull away soft, fluffy, cloud-like tufts, that is undercoat. If you mostly collect individual longer strands, or very little at all, you are probably dealing with a single coat.
5. Check the density
Double coats are thick. Fur often stands out from the body rather than lying flat, and it can feel hard to push your fingers through to the skin. Single coats lie closer to the body and are easier to part.
6. Think about how the coat looks groomed
A double-coated dog that has been brushed out looks full and fluffy, with a puffy outline. A single-coated dog tends to look sleeker or neater, with the coat falling in one smooth layer, or in curls.
A Quick Comparison
| Double-coated | Single-coated | |
| Layers | Topcoat (guard hairs) plus dense undercoat | Topcoat only, little or no undercoat |
| Feel | Plush, woolly underneath, often two textures | Uniform: silky, wiry or curly |
| Parting the fur | A second, fluffier layer is visible | One layer straight to the skin |
| Shedding | Seasonal "blowing coat", big tufts | Steadier, finer, less dramatic |
| Brushing | Soft fluffy tufts come out | Mostly individual hairs |
| Typical dog examples | Husky, Samoyed, Akita, Pomeranian | Poodle, Yorkshire Terrier, Maltese |
| Typical cat examples | Maine Coon, Norwegian Forest Cat, Ragdoll | Many shorthaired and fine-coated cats |
Examples of Each Coat Type
Our website lists the breeds we know to be double coated. A few of the ones you will find there:
Double-coated dogs: Akita, Alaskan Malamute, Siberian Husky, Samoyed, Chow Chow, Pomeranian, Shiba Inu, Keeshond, Finnish Lapphund, Bernese Mountain Dog, German Shepherd, Old English Sheepdog, Newfoundland, Rough Collie.
Double-coated cats (per our list): Maine Coon, Siberian, Norwegian Forest Cat, Persian, Himalayan, Ragdoll, British Shorthair.
Other fluffy fibre-producers: Angora and Lionhead rabbits.
Single-coated examples: The simplest rule from our site is this: if your breed isn't on the double-coated list, it is probably single coated. Common single-coated dogs include Poodles, Yorkshire Terriers, Maltese and Greyhounds. If your pet is clipped when groomed the likelihood is that the fur is single-coated or will be too short for spinning.
The full list lives on our pet fur spinning page, and it is much longer than the highlights above.

The Tricky Cases: Mixes, Cats and "Not All of Them"
Coats are not always tidy.
• Mixed breeds: A cross between a double-coated and a single-coated breed can end up with either, or something in between. Do the parting test rather than relying on the breed guess.
• "Not all are" breeds: Some breeds, like Border Collies and Australian Cattle Dogs, vary from dog to dog. Some have a lovely thick undercoat and some don't, so check the individual.
• Cats: Cat coats come in four main types: shorthaired, longhaired, curly-haired and hairless. Shorthaired cats often have a single coat without a thick underlayer, while longhaired cats can be either single or multi-layered. Curly breeds like the Devon Rex and Cornish Rex have a different coat structure again.
• Seasons: A double coat is at its fluffiest just before and during a shed. Judging a coat in the middle of summer can make it look thinner than it really is.
When in doubt, take a close-up photo with the fur brushed out and still attached to your pet, and send it our way. We can usually tell straight away.
What This Means for Spinning Yarn
Here is the part where we promise to be honest with you, because you deserve that.
Double-coated fur: the star of Chiengora
The soft, dense undercoat is what makes a strong, beautiful yarn. Double-coated fur can usually be spun as it is, and you can choose between DK and Aran/Worsted weight. The fur needs to be over half an inch long, so we recommend avoiding the short leg fluff.
This is the yarn you can knit or crochet into hats, scarves and cosy things you will actually wear.
Single-coated fur: a keepsake first
Single-coated fur is a different story, and we want you to know exactly what to expect.
• It must be at least 2 inches (5cm) long. If strands are under 1.6 inches (4cm), the yarn becomes unstable and can fall apart.
• It needs to be blended with sheep's wool for strength and spinnability.
• It can only be spun as Aran/Worsted weight, because thinner yarns may fall apart.
• The shorter the fur, the more spiky and coarse the yarn will feel.
In plain words: single-coat Chiengora is lovely as a memorial piece, but it is not a soft, snuggly yarn for wearing next to the skin. It is more of a treasured keepsake than a workable everyday yarn.
That is not a bad thing. Many of our favourite projects are exactly that: a little twist of yarn, a heart keepsake, something to hold on to that is truly from your pet. As one customer put it, the yarn was coarser than she expected, but "clearly Olly's fur" and made to last. If that sounds like what you are after, single-coated fur can absolutely work.
Frequently Asked Questions
Can I spin fur from a single-coated pet?
Yes, as long as the fur is at least 2 inches long and blended with sheep's wool. Expect a coarser, spikier yarn that works best as a memorial keepsake.
How long does the fur need to be?
Double-coated fur needs to be over half an inch long. Single-coated fur needs to be at least 2 inches (5cm).
My breed isn't on your list. What now?
It is probably single coated, but coats vary. Send us a close-up photo of brushed-out fur still on your pet and we will take a look.
Can I send fur from my pet's last groom?
Often, yes. Just make sure it is not matted or tightly packed, as that can cause felting. Gently sort through it and remove any mats first.
Can cat fur be spun?
Yes. Cats with a double coat, like Maine Coons and Ragdolls, are on our list. Fine, short-haired cats may not have enough length.
Do you have a waiting list?
We do. The current waiting list for Chiengora spinning is around 11 months (as of November 2026). It is updated regularly, so it may change, and cancellations occasionally open up earlier slots.
Ready to Find Out Whether Your Pet's Fur Will Spin?
Here is the easy route:
1. Have a look at our breed list and photo examples.
2. Do the part-the-fur test at home.
3. Still unsure? Send us a few close-up photos and we will tell you what we think.
A little note on timing: the Chiengora waiting list is currently about 11 months (as of November 2026), so it is worth getting in touch sooner rather than later. And because we are a small farm, replies may take a little while, but we do always answer.
Whether your pet has a fluffy double coat or a sleek single one, their fur is worth keeping. We would love to help you turn it into something you can hold on to.
