Dog Raincoats: Which Dogs Need One and How to Choose the Right Fit
Temperature guidance reflects common veterinary advice for cold and wet weather. Dogs with heart, thyroid, or joint conditions may need extra protection; ask your vet.
Key Takeaways
- Not every dog needs a raincoat. Small, short-coated, thin, senior, and short-legged dogs benefit most; dense double-coated breeds usually do not.
- Wet fur loses much of its insulating power. Small and thin-coated dogs can start to struggle in cold rain once temperatures fall below about 45 degrees F, and below 32 degrees F the risk rises quickly.
- Measure back length (base of neck to base of tail), chest girth, and neck girth before you buy; chest girth is the measurement that most often decides the size.
- A good raincoat is waterproof but breathable, covers the chest and belly, leaves the legs free, and has a leash port or harness opening.
- Dry your dog thoroughly after every wet walk, especially between the toes and in skin folds, to prevent yeast and bacterial skin infections.
- Watch for shivering, slowing down, lifting paws, or seeking shelter. These are early signs of being too cold, raincoat or not.
The forecast says rain until Thursday, and your Whippet is standing at the back door with the expression of someone being asked to walk into the sea. He takes three steps onto the soaked lawn, shivers, and turns around. Meanwhile your neighbor’s Labrador is happily splashing in a puddle. Both dogs are behaving exactly as their coats would predict. One has almost no insulation and loses heat fast when wet; the other is built for cold water.
This guide explains which dogs actually benefit from a raincoat, how to measure and fit one, the features worth paying for, how to introduce it, and how to protect your dog’s skin after wet walks.
Why Some Dogs Need Raincoats and Others Do Not
A dog’s coat traps a layer of still air against the skin. That air is the insulation. When fur gets soaked, water replaces the air, the coat flattens, and heat moves from the skin into the water far faster than it would into dry air. Add wind and evaporation, and a wet dog can cool down quickly even on a mild day.
Breeds with a dense double coat, such as Labrador Retrievers, Newfoundlands, and Siberian Huskies, have oily guard hairs that shed water and a thick undercoat that stays fairly dry underneath. Breeds with a short single coat or very little body fat lack that buffer.
| Dog Type | Example Breeds | Raincoat Benefit | Why |
|---|---|---|---|
| Small and toy breeds | Chihuahua, Yorkshire Terrier, Miniature Pinscher, Toy Poodle | High | Small bodies lose heat quickly relative to their size |
| Short single coat | Boxer, Dalmatian, Boston Terrier, Vizsla, Pug | High | No undercoat to stay dry and insulate |
| Lean sighthounds | Greyhound, Whippet, Italian Greyhound | Very high | Thin skin, very low body fat, short coat |
| Short legs, low bellies | Dachshund, Basset Hound, Corgi | Moderate to high | Bellies brush wet grass and puddles |
| Long silky coats | Maltese, Shih Tzu, Cocker Spaniel | Moderate | Coat soaks through and mats, taking hours to dry |
| Dense double coat | Labrador, Husky, Malamute, Newfoundland | Low | Water-resistant guard hairs and thick undercoat |
| Seniors, puppies, and dogs with illness | Any breed | Higher than normal | Weaker temperature control |
Temperature and Weather Guide
There is no single cutoff that fits every dog, but these ranges are a sensible starting point for wet weather. Wind and rain make every temperature feel colder.
| Air Temperature | Small or Thin-Coated Dogs | Medium Dogs With Normal Coats | Large Double-Coated Dogs |
|---|---|---|---|
| Above 60 F, light rain | Raincoat optional, mostly to keep clean | Not needed | Not needed |
| 45 to 60 F, rain | Raincoat recommended | Optional | Not needed |
| 32 to 45 F, rain or sleet | Lined, insulated waterproof coat | Raincoat recommended | Usually fine; dry well after |
| Below 32 F | Insulated coat, short walks only | Insulated coat for long walks | Watch for ice in paws; coat for seniors |
Types of Dog Raincoats
Lightweight Rain Shell
A thin, unlined waterproof layer that keeps rain off the back and sides. Best for mild weather and dogs that run warm. Packs small for travel.
Lined or Fleece-Lined Raincoat
A waterproof outer shell with a soft fleece or quilted lining. The right choice for small and thin-coated dogs in cool rain, since it keeps them both dry and warm.
Full-Body Rain Suit
Covers the legs and belly as well as the back. Useful for low-slung dogs, long-coated dogs whose feathering soaks up mud, and owners who want to skip the post-walk bath. Some dogs find suits restrictive at first.
Poncho Style
Slips over the head with a belly strap or two. Easy to put on, but leaves the chest and belly more exposed and can flap in wind.
Reflective or High-Visibility Coat
Bright colors and reflective panels help drivers see your dog on dark, rainy evenings, when visibility is at its worst.
How to Measure Your Dog for a Raincoat
- Back length: measure from the base of the neck, where the collar sits, to the base of the tail. This is the number most brands list as “size,” but it is rarely the one that matters most.
- Chest girth: measure around the widest part of the rib cage, just behind the front legs. Deep-chested breeds such as Greyhounds and Boxers often size up based on this measurement.
- Neck girth: measure around the neck where a collar would sit, then add 1 to 2 inches for comfort.
- Compare to the brand chart, not to your dog’s size in another brand. If your dog falls between sizes, go by chest girth and choose the larger size if the coat has adjustable straps.
- Check the fit once it arrives. You should fit two fingers under the neck opening and straps. The coat should end at the base of the tail, not cover it, and the legs should move freely without rubbing at the armpits.
For male dogs, check that the belly panel sits forward of the penis so the coat does not get soaked every time he urinates.
Features Worth Paying For
- Waterproof and breathable fabric: fully waterproof coats with no ventilation trap body heat and moisture, which can leave the coat damp underneath.
- Chest and belly coverage: much of the cold and wet comes from below, from wet grass and puddles.
- Harness or leash opening: a zippered or slit port lets you clip to a harness underneath. Never clip a leash to a coat itself.
- Adjustable chest strap and hook-and-loop closures: easier to fit and faster to put on a wriggling dog.
- High collar or hood: keeps rain off the neck. Many dogs dislike hoods, so choose a removable one.
- Reflective trim: worth it for any dog walked before sunrise or after dark.
- Machine washable: rain gear gets muddy fast.
Choosing for Your Climate
Where you live changes what you need. In mild, wet climates such as the Pacific Northwest, a breathable unlined shell that you can wash often is worth more than heavy insulation. In regions with cold rain and sleet, choose a lined coat with a high collar and full chest coverage. In hot, humid places with summer storms, pick the lightest waterproof fabric you can find, keep walks short, and skip the coat entirely for double-coated dogs. If you hike in all seasons, two coats (a light shell and an insulated jacket) cover far more days than one compromise coat.
What Dog Raincoats Cost
| Type | Typical US Price | Best For |
|---|---|---|
| Basic rain shell or poncho | $15 to $30 | Mild weather, occasional use |
| Lined waterproof coat | $30 to $70 | Small and thin-coated dogs, cool climates |
| Full-body rain suit | $35 to $80 | Low-slung and long-coated dogs |
| Technical outdoor jacket | $60 to $120 | Hiking and very wet climates |
How to Get Your Dog Used to a Raincoat
- Let your dog sniff the coat on the floor and reward calm interest.
- Drape it over the back for a few seconds without fastening anything, then treat and remove it.
- Fasten one strap at a time over several short sessions indoors.
- Practice the sound of hook-and-loop straps with treats, since the ripping noise startles some dogs.
- Walk around the house in the coat, then step outside on a dry day before trying it in rain.
- Keep the first wet walks short and fun. If your dog freezes or tries to rub the coat off, go back a step.
Raincoat, Winter Coat, or Sweater?
| Garment | Keeps Out Rain | Adds Warmth | Best Use |
|---|---|---|---|
| Rain shell | Yes | Little | Mild, wet days and active dogs |
| Lined raincoat | Yes | Moderate | Cool, wet days for small and thin-coated dogs |
| Insulated winter coat | Usually water resistant | High | Freezing temperatures, snow, and wind |
| Sweater or hoodie | No (soaks through) | Moderate when dry | Dry, chilly days and indoors for seniors |
A soaked sweater can make a dog colder than wearing nothing, because wet wool or cotton holds water against the body. In rain, a waterproof layer always goes on top. For heavier cold-weather gear, see our guides to dog coats and dog hoodies.
Staying Safe on Rainy Walks
- Avoid standing water and puddles. Puddles and floodwater can carry Leptospira bacteria from wildlife urine. Leptospirosis can damage the kidneys and liver and can spread to people. Ask your vet whether the leptospirosis vaccine suits your dog’s lifestyle, and read our guide to dog leptospirosis.
- Watch for antifreeze and oily runoff on driveways and roads. Ethylene glycol antifreeze tastes sweet and is deadly in small amounts. Rinse paws after walking through slicks.
- Be visible. Rain cuts driver visibility, especially at dusk. Use a reflective coat, a light-up collar, and a reflective leash.
- Shorten walks in storms. Thunder and lightning frighten many dogs, and a startled dog can slip a loose coat or collar. Make sure the harness fits snugly under the raincoat.
- Mind slippery surfaces. Wet tile, decking, and metal grates are slick for senior dogs and dogs with arthritis.
Skin and Coat Care After Wet Walks
Rain gear keeps most water off, but paws, legs, and faces still get wet. Moisture trapped against the skin is a common trigger for skin problems.
- Towel dry thoroughly, then let your dog finish drying in a warm room. Use a cool hair dryer setting for thick or long coats.
- Dry between the toes and paw pads, where yeast thrives. Read more about dog paw yeast infections.
- Check and dry skin folds on Bulldogs, Pugs, and Shar-Peis.
- Dry the ears of floppy-eared breeds, which trap moisture and can develop infections.
- Rinse mud and road grime off legs and bellies, and use a dog paw cleaner for quick cleanups at the door.
- Hang the raincoat to dry away from direct heat, inside out, before the next walk.
Common Myths About Dog Raincoats
Dogs have fur, so they never need coats.
Fur works well when dry. Small, short-coated, and thin dogs lose heat quickly once their coat is soaked, especially in wind.
Raincoats are just fashion.
For senior dogs, sighthounds, and toy breeds, a raincoat can be the difference between a comfortable walk and a shivering, miserable one. Style is a bonus.
A tighter coat keeps out more rain.
A coat that is too tight rubs the armpits and restricts movement. Fit with room for two fingers under every strap.
Big double-coated dogs need raincoats in winter.
Most Huskies, Malamutes, and Newfoundlands are built for cold and wet weather and can overheat in a coat. Seniors and sick dogs are the exception.
Red Flags: Get Your Dog Warm and Call the Vet
- Shivering that does not stop after 10 to 15 minutes indoors.
- Weakness, stumbling, or unwillingness to stand.
- Pale or blue-tinged gums.
- Confusion or unusual sleepiness after a cold, wet outing.
- Skin on ears, tail, or toes that looks pale, gray, or hard, then red and swollen (possible frostbite).
- Red, smelly, or greasy skin between the toes or in folds after repeated wet walks.
- Coughing or labored breathing after exposure to cold rain.
Age-Specific Considerations
Puppies (under 12 months)
- Puppies lose heat faster than adults; keep wet walks short.
- Buy adjustable coats, since they will outgrow fixed sizes quickly.
- Introduce gear early so it becomes normal.
Adult Dogs (1 to 7 years)
- Choose coat weight by breed, coat type, and climate.
- Active dogs may need a light shell, not insulation.
- Recheck fit after weight changes.
Senior Dogs (7 years and older)
- Older dogs often feel the cold more and may have arthritis that worsens in damp weather.
- Pick coats that fasten easily without lifting legs.
- Dry thoroughly; seniors are slower to warm up.
Frequently Asked Questions About Dog Raincoats
Do dogs really need raincoats?
Some do and some do not. Small, short-coated, lean, senior, and short-legged dogs benefit most, because wet fur loses its insulating air layer and these dogs have little extra protection. Dense double-coated breeds like Labradors and Huskies usually stay comfortable in rain without one, though seniors and sick dogs may still need help.
At what temperature does a dog need a coat in the rain?
Many small, thin-coated, puppy, and senior dogs benefit from a raincoat once temperatures drop below about 45 degrees F, and an insulated waterproof coat below 32 degrees F. Wind makes it feel colder. Watch your dog: shivering, slowing down, and lifting paws mean it is too cold, whatever the thermometer says.
How do I measure my dog for a raincoat?
Measure back length from the base of the neck to the base of the tail, chest girth around the widest part of the rib cage behind the front legs, and neck girth where a collar sits. Compare all three to the brand’s size chart, and let chest girth decide if your dog falls between sizes.
Should a dog raincoat cover the belly?
For most dogs, yes. A lot of cold and water comes from wet grass and puddle splash underneath, especially for short-legged breeds. Choose a coat with a chest panel and some belly coverage, and on male dogs check that the panel sits forward enough to stay clear when he urinates.
Can my dog overheat in a raincoat?
Yes, especially in mild or humid weather, during exercise, or with heavy double coats. Choose breathable waterproof fabric, use unlined shells above about 60 degrees F, and watch for heavy panting, a hanging tongue, or slowing down. Take the coat off once your dog is indoors and dry.
How do I get my dog to wear a raincoat?
Go slowly with treats. Let your dog sniff the coat, drape it over the back for a few seconds, then fasten one strap at a time over several short indoor sessions. Practice on dry days before rainy ones. If your dog freezes or rolls, go back a step and keep sessions shorter.
How do I wash a dog raincoat?
Most coats can be machine washed on a gentle cold cycle with mild detergent; check the label first. Close hook-and-loop straps so they do not snag. Skip fabric softener, which can reduce water repellency, and hang the coat to air dry away from direct heat. Rinse off mud between full washes.
