How to Choose the Right Dog Raincoat: A Guide to Fabric, Fit, and What Actually Keeps a Dog Dry

La Pluie Dog Softshell Raincoat — Colette et Gastón

On fabric, fit, and what a luxury dog raincoat actually needs to do.

Most dog raincoats are made to photograph well, not to work. They come in loud prints and lurid colours. They are cut from plastic-adjacent fabrics that trap heat and moisture inside the coat rather than keeping the weather outside. And they are usually the same pattern in six sizes — as if the difference between a Yorkshire and a Cocker Spaniel is a matter of scale.

A luxury dog raincoat is a different proposition. It is a considered piece of outerwear, drafted to sit correctly on the dog, cut in a fabric that keeps the water out without keeping the dog in.

Here is what to look for.

Fabric — the first thing that matters

Water resistance is not a single property. It exists on a spectrum, from truly waterproof (nothing gets through, but nothing breathes either) to water-repellent (the fabric sheds water while still allowing air to move through).

For a luxury dog raincoat, water-repellent is almost always the right choice. Truly waterproof coats work for humans standing still in the rain — for dogs, who are constantly moving, generating body heat, and stopping to sniff at things, they trap moisture inside. The dog ends up wet from the inside out.

What to look for:

  • Water-repellent technical cotton, softshell, or breathable nylon
  • PFC-free finish — safer for the dog and the environment
  • Not lined for warmer months; lined softshell for colder rain

What to avoid:

  • PVC or vinyl coats — truly waterproof, but they do not breathe at all
  • Heavy fleece linings on summer coats — these turn a raincoat into an oven
  • Nylon shells with printed patterns — cheap and prone to peeling

Fit — the second thing that matters

A dog raincoat that does not fit properly is worse than no raincoat at all. It rides up in the wind, pulls at the shoulders, exposes the belly to rain, and slides off entirely if the dog shakes.

The most common mistake luxury dog raincoat brands make is offering the same pattern in six sizes. A Yorkshire and a Cocker Spaniel are not the same shape — they have different back lengths, different chest widths, different leg proportions. A single pattern scaled up and down does not fit either correctly.

Dachshunds are the most common victim of this. A dachshund’s long back and deep chest need an entirely separate pattern — not a small raincoat made longer.

What to look for:

  • Sizing by breed silhouette, not by weight — a Whippet and a French Bulldog can weigh the same but need entirely different cuts
  • Separate patterns for dachshunds — a proper Teckel cut, not a scaled version of the standard
  • Clear measurement guides — back length, chest, neck — and generous return policies for size exchanges

Construction — the third thing that matters

The details of a raincoat are what make it wearable over time.

Closure. Velcro is easy but fails after a few seasons — it collects hair and stops holding. Buttons and buttoned plackets, especially with a storm flap beneath, last longer and look better.

Harness opening. Most raincoats have a slit on the back for the harness. Cheaper coats leave this exposed — water gets in every time it rains. Better coats have a concealed opening behind a buttoned placket. On our own Trench, this is a vertical opening — invisible when closed, quick to open for the harness.

Belt or waist. An adjustable waist keeps the coat fitted as the dog moves. A knotted fabric tie holds better than a plastic buckle and is quieter — no clicking, no snagging.

Storage. An integrated back pochette, sized for what you actually carry on a walk — a key, a folded bag, a treat — is the detail that separates a considered coat from a fashion prop.

Care — what to do after you buy

A luxury dog raincoat, cared for properly, lasts years. Cared for badly, it lasts one season.

Between wears: Wipe clean with a damp cloth. Never store the coat wet — the water-repellent finish weakens if the coat is folded and stored damp.

For deeper cleaning: Hand-wash cold with a mild detergent. Never use bleach or fabric softener — both strip the water-repellent finish. Rinse thoroughly. Lay flat to dry, away from direct heat or sunlight.

Over time: The water-repellent finish can be refreshed with a reproofing spray designed for technical cotton. Nikwax and Grangers both make good ones. Reproof once a year, and the coat performs like new.

Our own raincoats

At Colette et Gastón, our raincoats are cut and sewn in a small atelier in Paris. Every piece is water-repellent, considered in construction, and drafted to sit correctly on the dog.

The collection is four pieces:

The Trench Rain-Coat — the classic trench silhouette, reimagined for the dog. Double-breasted closure with horn-finished buttons over a storm flap. A soft fabric tie at the waist, knotted rather than buckled. An integrated back pochette. And the detail you will only notice when you put it on: a vertical harness opening, concealed behind a buttoned placket, so the line of the coat is never broken by hardware. In Sable and Noir. From €200.

The Teckel Trench Rain-Coat — the same considered construction, drafted on a long-bodied frame for the dachshund. Because a dachshund is not a small dog. It is a differently proportioned dog, and it deserves a raincoat cut on its own pattern. From €200.

La Pluie Softshell — a warmer option for colder rain. Lined, structured, and cut for winter walks. From €160.

La Pluie Light — a packable, unlined raincoat for spring rain, summer showers, and travel. From €140.

All four are made in France, small-batch, and numbered.

One final thing

A dog raincoat is not an accessory. It is a piece of outerwear for a dog who lives in a place where it rains — which is to say, most dogs.

The right one lasts years. The wrong one goes in a drawer after two walks.
