Dog coats aren’t about fashion; they’re a functional, even essential, piece of gear for many dogs. As a responsible pet parent, it’s crucial to know when a coat is necessary and which dogs benefit most from wearing one. This guide will walk you through everything you need to know—from identifying which breeds need jackets to choosing the right style, fit, and features. We’ll also cover how to measure your pup, how to maintain their coat, and how to tell if your furry friend is actually cold. 

So, whether you’re braving icy hikes or just strolling the neighborhood during a brisk morning, this guide has got you and your pup covered—literally.

Which Dogs Need Coats in Winter?

Not every dog comes equipped with a thick fur coat like a Siberian Husky. Some breeds were designed for colder climates, while others evolved in warmer regions and struggle with frigid temperatures. Here’s a look at which dogs benefit most from winter wear.

Small and Toy Breeds

Little dogs lose heat faster than their larger counterparts. Breeds like Chihuahuas, Yorkies, and Pomeranians are low to the ground, have small bodies, and often thin fur—making them highly susceptible to chilly temperatures. Their small size means they have a high surface-area-to-body-weight ratio, which causes them to lose heat more quickly.

Even when these breeds are layered up in fluff, it's often not enough to protect them from icy wind or sleet. A snug, insulated coat can offer the extra protection they need to stay warm and enjoy their daily walks, even in snow.

Plus, let’s be honest—watching a shivering tiny pup try to do its business in the snow is a sad sight. A properly fitted winter coat can make a world of difference for their comfort and health.

Short-Haired Breeds

Dogs with short, fine fur—like Boxers, Dobermans, Boston Terriers, and Pit Bulls—have little to no insulation. These breeds don’t have a dense undercoat and are often vulnerable to cold, wet weather. You’ll often see them trembling or trying to rush back inside when it's cold out.

These breeds particularly benefit from warm and even waterproof coats during the winter months. You can think of their fur like a t-shirt—it just doesn’t cut it when the temperature drops. Without additional layers, they’re at risk for hypothermia and frostbite, especially in snowy or windy conditions.

If you own a short-haired breed and live in a cold climate, investing in a high-quality winter coat isn’t just smart—it’s necessary.

Dogs With Clipped or Shaved Coats

Dogs that are regularly groomed or shaved, including Poodles (toy, miniature, and standard), Shih Tzus, and certain mixed breeds, lose their natural insulating barrier. Even if a breed typically has a warm coat, grooming can drastically reduce its ability to retain heat.

And it’s not just about fashion clips. Sometimes dogs need to be shaved for medical reasons or due to matting, especially rescues or long-haired dogs adopted after a period of neglect. In these cases, a coat becomes essential for warmth and protection.

Keep in mind that dogs with hair instead of fur (like Poodles) don’t have the same undercoat to keep them warm. These pups are especially prone to getting chilled and require a good winter coat when going outdoors.

Lean and Muscular Breeds

Lean-bodied dogs such as Greyhounds, Whippets, and Italian Greyhounds are notorious for their sensitivity to the cold. Their body composition—long legs, minimal fat, and short fur—means they have little to no protection from the elements. You might as well wrap them in a blanket and call it a day.

These breeds often require not just a jacket but a full snowsuit, especially in very cold climates. Some owners even layer fleece sweaters underneath waterproof outer layers for maximum insulation. For sighthounds and other sleek-bodied dogs, warmth is not a luxury—it’s a necessity.

If you’ve ever seen a Greyhound in winter, you know they’re not built for the cold. Give them the gear they need to thrive outdoors.

Elderly, Sick, or Very Young Dogs

Older dogs, puppies, or those with health conditions often have compromised immune systems or reduced fat and muscle mass, making them more susceptible to cold weather. Conditions like arthritis or hip dysplasia can be aggravated by cold, damp environments. A warm coat can ease joint pain and make outdoor potty breaks more comfortable.

Likewise, young puppies don’t yet have the full muscle development or stamina to generate heat. Even if they’re a cold-weather breed, they still need extra protection in their early months.

Sick dogs recovering from surgery, illness, or injury also fall into this category. They may not be able to regulate their body temperature as effectively and could use some extra help staying warm outdoors.

Breeds That Usually Don’t Need Coats

While some dogs shiver the moment winter hits, others seem to thrive in the cold—almost as if they were born for it (because they were). Let’s take a look at the kinds of dogs that can usually handle low temperatures without much fuss.

Cold-Climate Working Breeds

Certain dog breeds were bred specifically to work in cold, snowy environments, which means they’ve developed thick, double-layered coats to insulate them against extreme weather. These breeds are the tanks of the canine world—built for endurance, power, and warmth.

Some of the most cold-hardy breeds include:

• Alaskan Malamutes

• Siberian Huskies

• Saint Bernards

• Newfoundlands

• Bernese Mountain Dogs

• Tibetan Mastiffs

These dogs typically have a dense undercoat that traps warm air close to the body, combined with a coarser outer coat that repels snow and moisture. For them, wearing a coat might actually do more harm than good by causing overheating or disrupting their natural insulation.

That said, there are exceptions. If your Saint Bernard is elderly, sick, or has been groomed short, they might still need extra protection. And if the temperature dips into dangerous levels—below 0°F (-18°C)—even these breeds may benefit from a lightweight coat during extended outdoor exposure.

Dogs With Thick Double Coats

Double-coated breeds like German Shepherds, Shiba Inus, Akitas, and Chow Chows have natural protection against cold weather. These breeds evolved in colder parts of the world, and their thick, plush coats serve as excellent natural insulators.

A healthy, well-groomed double coat acts as a built-in thermal blanket. It traps body heat close to the skin and blocks out wind, moisture, and cold air. Adding an artificial layer, like a coat, can interfere with this process—especially if it's not breathable. These dogs often pant or try to remove the coat because they're simply too warm.

So, unless your thick-coated pup is old, underweight, or going to be outside for a long time in extreme conditions, it’s best to let their natural coat do the job. Just make sure you brush it regularly to prevent matting, which can reduce its insulating effectiveness.

Other Situations Where a Dog Might Need a Coat

Even if your dog belongs to a cold-tolerant breed, certain situations call for added warmth. Environmental factors, health conditions, and activity levels all play a part in determining whether a coat is necessary.

After Surgery or Illness

Recovery periods can make dogs more vulnerable to the cold, especially if their immune system is weakened or they’ve had fur shaved for a medical procedure. A coat can help maintain body temperature and prevent chills while they heal.

Dogs recovering from spaying/neutering, tumor removal, or skin treatment often have exposed areas with minimal protection. A soft, fleece-lined coat can offer warmth and comfort without irritating stitches or wounds. Just ensure it’s breathable and not too tight to avoid interfering with healing.

If your vet gives the green light, go ahead and use a coat to keep your dog cozy during recovery—but always monitor for signs of discomfort or overheating.

Wet or Windy Weather Conditions

Even dogs that tolerate cold well may struggle with wind and wet conditions. A dry coat insulates better than a wet one, and rain or melting snow can soak through even the thickest fur. Wind adds another layer of discomfort by cutting through fur and stealing body heat quickly.

This is where a waterproof and wind-resistant coat shines. Think of it as a rain jacket or windbreaker for your dog. It doesn’t have to be super insulated—just enough to keep their fur dry and shielded from gusts.

This type of gear is particularly helpful for high-energy dogs who still want to run, hike, or play outside during stormy days.

Long Outdoor Activities in the Cold

Extended outdoor exposure is another reason to invest in winter wear, regardless of breed. If you're going on a long hike, camping trip, or extended walk in sub-freezing temps, it’s always smart to bring a coat for your dog.

Even snow-loving breeds can get cold after hours outside, especially if they stop moving. A warm, insulated jacket helps conserve energy and body heat during periods of rest or low activity.

Plus, it’s easier to enjoy outdoor adventures when your dog is comfortable. No one wants to cut a hike short because their pup is shivering or trying to burrow under a bush to escape the wind.

Types of Dog Coats and Their Purpose

There’s no one-size-fits-all when it comes to dog coats. Just like people have options—light jackets, raincoats, puffers—dogs need different types depending on their size, breed, activity level, and the weather. Here’s a breakdown of the most common types of dog coats and when to use them.

Lightweight Jackets

Perfect for mild chill or windy conditions, lightweight jackets are ideal for autumn walks or slightly cool mornings. They provide just enough warmth for dogs with short coats or sensitive skin without causing overheating.

These jackets are typically made from breathable, stretchable fabrics like fleece or cotton-poly blends. They’re easy to put on, comfortable for movement, and usually machine-washable.

Consider using a lightweight coat if:

• Your dog gets chilly on early morning walks.

• It’s too warm for full insulation but too cool to go bare.

• Your dog is recovering from grooming or medical treatment.

Insulated and Padded Coats

When temperatures drop below freezing, your dog needs serious warmth. Insulated coats, often filled with synthetic down or thermal lining, act like parkas for your pooch.

They’re best for:

• Dogs who are small, lean, or short-haired.

• Long periods outside in cold or snowy weather.

• Road trips, hiking, or outdoor play in winter.

Make sure the insulation doesn’t restrict movement or cause overheating. Look for breathable inner layers and adjustable straps to get the right fit.

Waterproof Raincoats

Raincoats are lifesavers—especially in wet climates. They help keep your dog’s fur dry, prevent mud splatter, and reduce that “wet dog” smell. Waterproof coats are typically made of nylon, polyester, or similar materials with sealed seams.

Raincoats are ideal for:

• Dogs who dislike being wet (looking at you, Bulldogs).

• Breeds with thick coats that take forever to dry.

• Avoiding post-walk clean-up sessions.

Many models include hoods or collars for added protection, reflective strips for visibility, and leash holes for harnesses.

Full Body Snowsuits and Bodysuits

These are the all-in-one solutions for dogs needing maximum coverage. Snowsuits typically cover the torso, legs, and sometimes even the neck or paws. They’re great for lean-bodied dogs or breeds with zero tolerance for cold, like Italian Greyhounds or hairless breeds.

Choose a bodysuit when:

• You’re in deep snow or frigid temperatures.

• Your dog has sensitive skin or prone to frostbite.

• You want to reduce snow clumps forming on long fur.

Keep an eye on your dog’s comfort and mobility. Some suits can restrict movement if not fitted correctly.

Choosing the Right Jacket for Your Dog

Now that you know what kinds of coats are available, let’s talk about how to choose the best one for your furry friend. It's not just about warmth—it’s about functionality, comfort, and safety.

Material and Insulation

First and foremost, think about the materials. For cold climates, you’ll want coats with thermal insulation, fleece linings, or quilted padding. For wet conditions, nylon or polyester shells with waterproof coatings are ideal.

Avoid cheap or non-breathable fabrics that trap moisture and cause irritation. Materials should be lightweight yet warm, flexible yet sturdy, and easy to clean.

Some high-quality dog coats even use tech fabrics that wick moisture away from the body or retain heat without adding bulk.

Fit and Comfort

The jacket should fit snugly but not too tight. Dogs should be able to run, jump, sniff, and relieve themselves comfortably. Watch out for restricted leg movement or jackets that slip off when your dog moves.

Check these points:

• Coverage of the chest and belly

• Adjustable neck and chest straps

• Room around the legs and shoulders

• Freedom to go potty without removing the coat

Poorly fitted jackets can cause skin rubbing, anxiety, or even pose a choking risk if they shift.

Design Features to Look For

Look for smart features that improve safety and convenience:

• Reflective trim for nighttime visibility

• Harness holes or loops for leash attachment

• Zipper or Velcro closures for easy wear

• Water-resistant coatings for rain and snow

• Sanitary cut-outs so your pup can potty with ease

These small details can make a big difference, especially if you’re dressing your dog daily.

Harness Compatibility and How to Use Them With Coats

As more dog owners opt for harnesses over traditional collars, coat compatibility has become an essential feature. It’s not always as simple as throwing a coat on and heading out the door—especially when your harness clips underneath the jacket.

Back-Clip vs. Front-Clip Harness Use

Most coats are designed with back-clip harnesses in mind. These harnesses connect near the dog’s shoulders, making it easier for leash holes to align with the attachment point. However, many coats don’t come with these openings, and for good reason: holes in jackets often let water in and warmth out.

Front-clip harnesses, which attach at the dog’s chest, present an extra challenge. If your dog wears one for training or better leash control, it might not line up with any jacket hole. In that case, you’ll need to get creative with how you layer your dog’s coat and harness.

Using Harnesses Over vs. Under the Coat

Some dog coats, like those from Chilly Dogs, are intentionally made without a leash hole. The recommended method? Harness over coat. If your coat fits snugly and isn’t bulky, it’s easy to secure most harnesses on top with minimal adjustment.

Benefits of wearing the harness over the coat include:

• Avoiding heat loss from harness holes

• Preventing water from leaking into the jacket

• Minimizing snagging risks from branches or gear

However, if your coat is puffy or extra thick, placing a harness over it might feel awkward or unstable. In this case, try a thinner base coat or fleece under the harness, then layer a weatherproof shell over the top and thread the leash through the front.

DIY Tips for Harness Openings

Still prefer to use the harness underneath? Take your dog’s coat to a tailor or seamstress to have a custom buttonhole added exactly where your leash ring sits. Keep the hole as small as possible to minimize exposure and protect the jacket’s insulation.

A reinforced, zippered opening or Velcro flap over the harness hole can be even more effective. Just remember, DIY modifications can void return policies or product warranties, so make sure it’s a coat you plan to keep.

How to Measure and Fit a Dog Coat Properly

Buying a dog jacket isn’t just about style or insulation—it’s about the perfect fit. A poorly fitted coat can cause discomfort, restrict movement, or even pose a safety risk. Here’s how to measure your dog like a pro.

Measuring the Chest, Back, and Neck

To get the best fit, you’ll need three key measurements:

1. Back Length – Measure from the base of the neck (where the collar sits) to the base of the tail.

2. Chest Girth – Measure the widest part of your dog’s chest, just behind the front legs.

3. Neck Circumference – Measure around the neck at the same spot as their collar.

Use a soft tape measure and don’t pull too tightly—you want the coat to fit snugly, not squeeze them like a sausage. If your dog is between sizes, always go up a size, especially for thicker coats or dogs with broad chests.

Ensuring Mobility and Comfort

A well-fitted dog jacket should:

• Allow full range of motion in the shoulders and legs

• Cover the belly (without interfering with potty breaks)

• Stay in place while your dog walks, runs, or jumps

• Not bunch up, twist, or slide to one side

Some dogs are pickier than others, so it may take a few tries to find a coat that your pup loves wearing. Try it on indoors first. If your dog can move, sit, and lie down comfortably, you’ve got a winner.

Also, don’t forget to check for adjustable straps, elastic leg loops, or Velcro panels—these can help fine-tune the fit for a more secure and comfortable experience.

Caring for Your Dog’s Jacket

Just like your own winter coat, your dog’s jacket needs regular maintenance to keep it clean, comfortable, and functioning properly.

Cleaning and Maintenance Tips

Dirty jackets aren’t just gross—they can also irritate your dog’s skin. Snow, mud, sweat, and fur buildup can create a breeding ground for bacteria, especially if the coat is stored damp.

Here’s how to keep your dog’s coat fresh:

• Read the label. Follow washing instructions carefully—most dog coats are machine-washable, but not all can go in the dryer.

• Use mild detergents. Avoid bleach or heavily fragranced products that could irritate your pup’s skin.

• Close Velcro and zippers before washing to prevent snags.

• Air-dry whenever possible to maintain shape and prevent shrinkage.

• Brush off dried mud and fur between washes.

Depending on how often your dog wears the jacket, aim to wash it every 1–2 weeks—or sooner if it smells funky or looks grimy.

Storage Advice for Off-Seasons

When winter’s over, don’t just toss your dog’s jacket in the closet. Proper storage helps extend its lifespan and ensures it’s ready to go next season.

• Wash it first to remove any dirt, salt, or bacteria.

• Store it in a breathable fabric bag (not plastic) to prevent mildew.

• Keep it in a cool, dry place away from direct sunlight.

• Consider placing cedar chips or lavender sachets nearby to ward off pests and odors.

Taking a few extra steps now means your dog’s coat will stay fresh, intact, and warm year after year.

Common Myths About Dogs and Coats

Let’s bust some myths. You’ve probably heard things like “dogs don’t need coats” or “only fancy purse dogs wear sweaters.” Well, it’s time to separate fact from fiction.

“Dogs Don’t Get Cold” Myth

This is one of the most common misconceptions. Sure, dogs have fur—but not all fur is created equal. A Chihuahua’s short, thin coat does not compare to a Malamute’s thick, dense double coat.

Many dogs can and do get cold. Hypothermia, frostbite, and cold stress are very real risks for certain breeds, especially when wet or exposed to harsh winds.

If your dog is shivering, lifting their paws off the ground, trying to turn back inside, or hunching close to the ground—they’re cold. And that’s your sign to put a jacket on them.

“Only Small Dogs Need Coats” Misconception

It’s true that small dogs are more vulnerable to the cold, but size isn’t the only factor. Body composition, fur density, and breed history matter more.

A lean, short-haired dog like a Greyhound may need a coat more than a fluffy Corgi, even though the Greyhound is twice the size. Don’t assume your large dog is immune to winter weather—assess their breed, coat type, and behavior before making that call.

Signs Your Dog Is Too Cold and Needs Protection

Dogs might not speak our language, but their body language is crystal clear when they’re cold. Learning to read the signs of discomfort can help you prevent bigger issues like hypothermia or frostbite.

Behavioral and Physical Clues

If your dog exhibits any of the following signs while outside, it’s time to bundle them up or head indoors:

• Shivering or trembling – This is the most obvious and immediate signal.

• Whining or barking – Vocal cues often indicate distress or discomfort.

• Lifting paws off the ground – Cold, icy sidewalks or snow can cause paw pain.

• Tucked tail and hunched posture – Dogs trying to conserve heat will curl their bodies inward.

• Seeking shelter – If your dog tries to head back inside or hides under something, they’re probably too cold.

• Slowed movement – A chilled dog may become lethargic or sluggish.

In extreme cases, cold exposure can lead to:

• Pale or blue gums

• Stiff muscles

• Rapid breathing

• Confusion or disorientation

These are signs of hypothermia and require immediate veterinary attention. Don’t wait until your dog’s teeth are chattering—gear up and be proactive.

When to Go Back Indoors

If it’s too cold for you to comfortably stand outside without a jacket, it’s probably too cold for your dog too—especially if they’re standing on cold pavement or walking through snow.

Use this basic temperature guide:

• Above 45°F (7°C): Most dogs are okay without coats.

• 32–45°F (0–7°C): Short-haired or small dogs may need a light jacket.

• Below 32°F (0°C): All but thick-coated breeds may benefit from insulation.

• Below 20°F (-6°C): Limit outdoor time and always use protective gear.

Pay attention to how long your dog is exposed, not just the temperature. Even cold-hardy breeds can get chilled after 20–30 minutes in sub-zero weather.

Can Dogs Overheat in Coats?

Yes, absolutely. While keeping warm is important, over-insulating can cause your dog to overheat, especially during high activity or in mild weather. Heatstroke can happen even in winter if dogs are layered too heavily or kept in their jackets indoors.

Indoor vs. Outdoor Use

Dog coats are meant for outdoor use only, unless your home is particularly drafty or cold. Once your pup is back inside:

• Take the coat off immediately

• Check for dampness or sweat

• Let their skin breathe

Wearing a jacket indoors can trap heat and moisture, leading to skin irritation, overheating, or even heatstroke in more sensitive dogs.

Monitoring for Overheating

Watch for signs of overheating, even in the cold:

• Panting or excessive drooling

• Red gums or tongue

• Lethargy or restlessness

• Rapid heartbeat

If you see these signs, remove the jacket and give your dog time to cool down in a comfortable environment. Never leave a jacket on unsupervised—especially when your dog is lying in the sun, inside a heated car, or next to a space heater.

Conclusion

Dog coats aren’t just cute—they’re practical, protective, and sometimes life-saving. While not every dog needs one, many do—especially small breeds, short-haired dogs, lean-bodied sighthounds, or pups with medical concerns. Understanding your dog’s breed, body type, age, and behavior is the key to knowing when to break out the winter wear.

Remember: your dog’s comfort and safety should always come first. If they’re shivering, hesitant to go outside, or struggling in the snow, a coat could transform their winter experience. And with so many styles, materials, and features available, you’re bound to find something that’s both functional and fashionable.

So this winter, as you zip up your own jacket, take a moment to ask—should your pup be zipping up too?

FAQs

1. Do dogs actually like wearing coats?

Many dogs don’t love coats at first, but with the right fit and gradual introduction, they can learn to tolerate—or even enjoy—wearing them. Choose lightweight, non-restrictive styles for starters and use treats to associate the coat with positive experiences.

2. What temperature is too cold for dogs without coats?

Dogs generally start needing coats below 45°F (7°C), especially if they’re small, short-haired, or senior. Below 32°F (0°C), most dogs should be protected unless they’re thick-coated northern breeds. At 20°F (-6°C) and under, limit outdoor time.

3. Are there breeds that should never wear a coat?

Thick-coated breeds like Siberian Huskies, Malamutes, and Newfoundlands usually don’t need coats unless they’re elderly, sick, or groomed short. Overdressing these breeds can lead to overheating and interfere with their natural insulation.

4. How long can a dog safely wear a coat?

Only as long as they’re outdoors and cold. Avoid leaving coats on indoors or for extended periods without breaks. Remove coats immediately when your dog comes back inside to prevent overheating and skin issues.

5. Can dog coats cause skin irritation?

Yes, if the material is non-breathable, dirty, or too tight. Always choose soft, breathable fabrics and ensure the jacket is clean and dry. Watch for signs like redness, itchiness, or hair loss under the coat area.
