The “Two-Finger” Rule: How to Fit a Dog Coat So They Actually Wear It

There is nothing cuter than a dog in a jumper.

And there is nothing more frustrating than buying that jumper online, waiting three days for it to arrive, and then realising it is tight across the chest or hanging off their back legs like a skirt.

Most dog owners have a drawer full of clothes that have been worn once. The dog freezes up when you put it on. They refuse to walk. They look at you with betrayal.

This usually happens not because the dog hates clothes, but because the fit is wrong.

If a coat restricts the shoulder blades, the dog cannot extend their front legs. They feel trapped.

Here is how to get the sizing right without trying it on in the store.

1. The Measurement Trinity

Do not guess. Do not assume your dog is a “Medium” because they are a Cocker Spaniel. Brands vary wildly. A Medium in Kazoo is different to a Medium in FuzzYard.

You need three numbers:



The Topline: From the collar to the base of the tail. This is your main number.



The Chest: The widest part of the ribcage (usually right behind the front legs).



The Neck: Where their collar sits.

2. The "Two-Finger" Rule

When the coat is on, you must be able to slide two fingers comfortably under the neck and the chest strap.

If you can only fit one finger, it will chafe their armpits when they walk. If you can fit your whole hand, they will likely urinate on the belly strap.

3. Choosing the Right Style

Not all shapes fit all breeds.



The Barrel Chest (Staffies, Pugs, Frenchies): These dogs have thick necks and wide chests but short backs. Standard coats often hang off their rear end. The Fix: You need stretch. The DGG Dog Warmie is perfect here. It is made from a polar fleece knit that stretches to accommodate the chest without restricting movement. It acts like a second skin.



The Long & Lean (Greyhounds, Dachshunds, Whippets): These dogs get cold easily because they have zero body fat. They need coverage over the hips. The Fix: Look for the Kazoo Adventure Coat. It has a longer cut along the spine and a heavy-duty waterproof shell. It protects the big thigh muscles from the rain.



The fluffy (Oodles, Pomeranians): If your dog has a lot of hair, a tight zip will snag. The Fix: Go for the FuzzYard Flash Jacket. It has a step-in design with a zipper on the back, so you are not wrestling with fur on their sensitive belly area.

Why They Freeze

If you put a coat on your dog and they stand statue-still, check the armpits.

If the fabric is cutting into the armpit, it hurts to move. This is the most common sizing error. This is why we love the DGG Warmie range—the leg holes are essentially non-existent (it is a sleeveless vest style), which gives total freedom to the front legs.

Don't Guess

Measure twice. Buy once.

And if you are still not sure, bring them into our Ivanhoe store. We have treats, we have a fitting mat, and we will make sure they can do a full “shake” before you buy.

Warmth Without the Wrestling

This is not just about fashion. It is about welfare.

An older dog with arthritis feels the cold in their joints. A short-haired dog feels the bite of the July wind just like you would without a jacket.

When you get the fit right, the battle ends. The coat stops being a “costume” and starts being a tool. Your dog stays warm, their joints stay supple, and you can both enjoy the winter walk without the shivering.

Measure the topline. Check the two-finger gap. And if you are stuck, bring them in. We would rather spend ten minutes fitting them properly than have you take home a coat that sits in the drawer forever.

Frequently Asked Questions

My dog hates coats. Can I train them to wear one?

Yes. The trick is to avoid “forcing” it on. Put the coat on the floor. Put treats on top of it. Let them sniff it. When you do put it on, give them a high-value reward (like cheese or chicken) immediately. Then go for a walk. They need to associate the coat with “fun,” not “confinement.”

What if my dog is between sizes?

Always size up. A slightly loose coat can still be worn (and you can often shorten a belly strap with a few stitches). A coat that is too small is useless; it will rub their armpits raw and they will refuse to move.

Do big dogs actually need coats?

It depends on the breed and age. A Husky does not need a coat. But a Greyhound, a Boxer, or an older Staffy with arthritis will feel the cold deeply. If you see them shivering or curling into a tight ball, they need an extra layer.

Can they sleep in these coats?

The DGG Warmie is safe for sleeping because it is soft and breathable (like pyjamas). Avoid leaving heavy waterproof coats (like the Kazoo) on overnight, as they can cause overheating or matting in the fur.
