Size Guide
Size Guide
How to measure: Measure around the widest part of the chest, just behind the front legs. The chest matters most; weight is a helpful guide. Between sizes? We recommend sizing up.

Better walks, whatever the weather.
Another grey, drizzly afternoon and a dog who still wants the long way round? The StormBreaker™ is a lightweight hooded raincoat that helps keep the worst of the rain and mud on the coat, not on your dog, your car seat or the sofa.

Why owners choose the StormBreaker™
- Back and hood coverage: shields the back, sides and neck, where the rain soaks in first. You towel off paws, not the whole dog.
- Reflective trim: helps your dog stand out in headlights on dark winter evenings and early mornings.
- Harness opening: clip your lead straight to the harness underneath. No coat-over-harness wrestling at the front door.

- Adjustable belly strap: a closer fit that helps stop the coat shifting while they trot, sniff and investigate.
- Handy rear pocket: a home for poo bags, so your own pockets stay free.
- On in seconds, off at the door: slip it on before the walk and peel it off when you are home. The mud leaves with the coat.



From Jack Russells to German Shepherds
Eight sizes, S to 5XL, in four bright colours chosen to be easy to spot on a dull day. With sizes going all the way up to 5XL, there's room for broad-chested and big-boned dogs too.
Size guide
Measure your dog's chest at its widest point, just behind the front legs, and compare it with the table below. Fit varies with body shape, so go by the chest measurement rather than breed.
| Size | Chestcm / in | Neckcm / in | Backcm / in | Weightkg |
|---|---|---|---|---|
| S | 30–3412–13.5 | 22–248.5–9.5 | 20–258–10 | 1–2 |
| M | 36–4014–15.5 | 26–2810–11 | 25–3010–12 | 2–3 |
| L | 42–4616.5–18 | 28–3011–12 | 30–3512–14 | 3–5 |
| XL | 50–5619.5–22 | 32–3612.5–14 | 35–4014–15.5 | 5–9 |

Centimetres shown first, inches below. Chest: around the widest part, just behind the front legs. Neck: where the collar sits. Back: base of the neck to the base of the tail.
These measurements are a guide: every breed and body shape is a little different, so please measure your dog carefully. If your dog is between sizes, or has a thick coat, we recommend sizing up for a more comfortable fit.
Still unsure? Email support@arkonpet.com with your dog's chest, back length and weight, and we will help you pick.

Made for real British weather
-
Early, wet mornings
The hood and back panel keep the worst of the drizzle off, so the walk still happens and your dog comes home drier.
-
Dark afternoons
Reflective trim picks your dog out in headlights, from the school run to the after-work walk.
-
Muddy car journeys
Peel it off at the door or the boot. The mud stays on the coat, not on your dog, your seats or the sofa.
Getting the size right
Three measurements and two minutes: chest, back length and neck. Between sizes? Go by the chest, or send us the numbers and a real person will recommend one.
Questions, answered
Which size should I choose?
Go by the chest: measure around the widest part, just behind the front legs, and pop the number into Find my size at the top of this page, or compare it with the table in the description. Between sizes, or a thick coat? Size up for a more comfortable fit. Still unsure? Send us the numbers and a real person will recommend one, usually within 1 working day.
Will it fit over a harness?
Yes. There's an opening on the back so you can clip your lead straight to the harness underneath, with no coat-over-harness wrestling at the front door.
Will it keep my dog dry?
It keeps the worst of the rain off the back, sides and neck, where a dog soaks through first, so you're towelling paws rather than the whole dog. It's a lightweight, water-resistant raincoat rather than a full body suit, so on a long downpour legs and tummy will still get wet. A CosyWrap by the door takes care of the rest.
Will it rub or get in the way?
It's light, leaves the legs free, and the adjustable belly strap lets you fine-tune the fit so it doesn't slide about while they trot and sniff. Rubbing is usually a sign of the wrong size, so measure the chest first. If anything looks tight, send us a photo and we'll help put it right.
Will my dog be seen on dark walks?
The reflective trim picks up car headlights and torchlight, and the four bright colours are easier to spot on a grey afternoon. For unlit lanes and pitch-dark evenings, add a clip-on light such as our NightBeacon.
When will it arrive, and are there any extra fees?
Orders are dispatched within 1–3 working days from our partner fulfilment centres in Asia. Most arrive within 8–14 days of ordering; please allow up to 18. Every parcel is tracked and delivery is free. VAT and import duties are already included in the price, so there's nothing extra to pay on the doorstep.
What if it doesn't fit?
Get in touch first and we'll help put it right. Send us a quick photo of your dog wearing the coat and a photo of the chest measurement, and we'll find the best way to sort it out together. You can also return an item within 30 days; as our returns centre is overseas, return postage is paid by you. Full returns policy.
Who are you? Is this a real UK shop?
Yes. Arkonpet LTD is a company registered in England and Wales (No. 17168016), based in Birmingham. Our products are sent from partner fulfilment centres in Asia, which is why delivery takes a little longer than the high street. Checkout is handled securely by Shopify, and every email to support@arkonpet.com is answered by a real person. Read our story.
How do I clean it?
Most days it just needs a wipe: let the mud dry, brush it off, then sponge it down with lukewarm water and a little mild soap. Hang it to air-dry away from radiators. For a deeper clean, please check the care label first.
