Cold days with snow, slush, and ice are enough to make all but the hardiest breeds think twice about stepping outdoors. That's where a quality coat comes in. While our pups certainly look cute all bundled up, the best dog winter coats help get them safely outside. And that's the whole point, says Dr. Brian Collins, a veterinarian with the Cornell Riney Canine Health Center. "The goal of a winter coat is to allow dogs to enjoy the winter weather, to stay comfortable and safe — just like us," he notes.

To find the best coats, we consulted veterinarians and spoke with over a dozen dog walkers and trainers from the coldest, snowiest cities in the US. We also conducted hands-on research with the help of four canine testers, ranging in size from tiny terrier to large shepherd. Out of the 12 coats we tested, the Hurtta Expedition Parka came out on top. It offers full waterproof coverage, excellent heat retention, and a wide range of sizes to suit most dogs, even the oddly — but adorably — shaped pups.

Best overall

Designed in Finland to withstand harsh Nordic winters, the Hurtta Expedition Parka features a waterproof shell, reflective trim, and an insulated lining to keep your dog toasty, dry, and visible on dark, cold days. This coat provides full coverage from top to tail, starting with the extra-large collar and extending all the way down the back.

In our testing to assess how well each coat retained heat, the Expedition Parka came out on top. It's also fully waterproof, not just water-resistant, which is surprisingly not always the case with winter coats. Our canine tester for this parka, an adventurous mixed breed named Roo, also stayed dry while wearing it on a soggy hour-long walk that dumped rain the entire time.

Offering an extensive range of 16 sizes, Hurtta covers the bases for dogs of all shapes. The brand even includes a few specialty sizes with wider chests and bigger necks to accommodate harder-to-fit breeds, like Dachshunds and smaller bully types. For the two smallest sizes, the coat has an integrated harness, but for the rest, there's a large leash opening in the back that snaps on each side.

Leg straps and four points of adjustment provide a streamlined fit with a buckled waistband and two drawstrings at the neck and one at the back. While the cinch for the length works wonders, the two for the collar don't do much to bring down its enormous size. Still, we found it easy to roll down for a quick fix.

It's also worth noting that because this is a very warm, full-coverage winter coat, it's best suited for colder months.

Best budget

Despite its budget-friendly price, the Petrageous Designs Juneau Coat provides impressive protection against the elements. Its heavyweight nylon shell with reflective trim looks and feels high-quality and outperformed other, more expensive options. In our testing, the shell did a fantastic job of repelling water and keeping the coat's interior completely dry during our soak test. A thick layer of poly fiber fill also retained heat amid the cold.

We particularly like how easy this coat is to put on and take off, thanks to its fixed neck and single belly strap that secures together with velcro at the top. Elastic leg straps are also available to keep the coat snugly in place. This coat is quite roomy in the chest, though. While ideal for Roo, our 40-pound barrel-chested rescue mix, it was a bit too much for our smaller 12-pound terrier tester.

The leash hole is also quite small and high on the neck, and didn't work well with both our harness-wearing dogs, whose leash rings were farther down their backs. It's also worth noting that this is a blanket-style coat that's a bit bulky and better suited for everyday walks rather than super-active romps.

For a more lightweight budget option, the Frisco Reversible Puffer may be a better choice. Just keep in mind that it's water-resistant, so it won't provide as much protection as the waterproof Juneau Coat.

Best belly coverage

For adventurous treks through deep snow or mud, the Ruffwear Powder Hound Jacket has your dog covered — quite literally! This form-fitting coat has stretchy cap sleeves and insulated chest and belly panels to keep your dog's underside warm and dry. A single zipper also runs the length of the left side for better core heat retention.

However, this design isn't the easiest to put on, and you may need an extra set of hands, especially for wiggly pups. Since dogs have to step through the sleeves, and the zipper stretches along the side, we found it took a few tries to zip the coat up without it falling down or our dogs walking out of it.

This coat was also quite snug for broad-chested Roo, but it fit her friend, a similarly medium-sized sheepadoodle, perfectly. If between sizes and your dog has a larger chest, it's best to size up.

Additional features include reflective trim on the back and a loop at the base of the neck to attach a light. Although this jacket doesn't have an opening to secure a leash, it's slim enough to easily fit a harness over it. And, while Ruffwear lists the shell as water-repellent, meaning it's only suitable for shedding light moisture, it passed our soak test just fine.

Best for large dogs

The Fjord Lined Raincoat boasts the longest length out of all the dog winter coats on our list, making it an optimal choice for large breeds. We tested this one with a 60-pound German Shepherd and found it offered an excellent fit.

Along with the generous sizing, this coat is very adjustable with two drawstrings at the high neck, one cinch point at the back, and an adjustable waistband. It was also one of the top-performing coats in our heat-retention testing, offering a design and coverage similar to the Expedition Parka but with a little less bulk.

The fleece lining is soft and snuggly, and the smooth, waterproof shell repels water effectively. Drainage holes at the belly keep water from collecting inside the coat, perfect for splashing through puddles and stomping through snow. There's also a large, wide leash hole at the back that aligns well with a harness and leg straps to keep everything in place. Thick, reflective lines are bright in low-light conditions — a much-appreciated feature in the winter months with fewer daylight hours.

At the time of writing, this coat is a new release, so there's only one color option. It's not the most affordable coat either, but we found the value and quality to be well worth the higher price.

Best vest

Acting as both a warm, comfortable coat and a durable harness, the Ruffwear Overcoat Fuse Vest helps consolidate your dog's winter gear.

We'll be honest, though. We were a little skeptical that a coat could provide the same support as a traditional harness, but this vest delivered. It was structurally sound even when walking Roo, a notorious puller, with the Y-shape helping to evenly distribute pressure across her chest and shoulders. In addition to an aluminum ring in the back, the coat has a webbed, looped leash attachment in the front to help curb pulling. Extras include reflective trimming, a loop for attaching a light, and zippered pockets on each side for storing poop bags or other small items.

As far as functionality goes, the fleece lining effectively kept the heat in, while the water-repellent shell kept light moisture out. However, unlike Ruffwear's Powder Hound, which kept the lining dry, this vest showed slight dampness after we soaked it and let it sit in the shower for half an hour as part of our waterproofing test.

This coat also runs a bit large — with the small size fitting Roo's medium frame perfectly. For a similar harness-coat design, the Canada Pooch Harness Puffer might be better suited for small dogs. The Ruffwear Vert is also an excellent choice if you prefer the same vest style, just without the harness.

What to look for in a dog winter coat

Collins says to first consider your dog's needs and preferences when picking out a dog winter coat. Is your dog more of a fair-weather friend who just needs a simple coat for potty breaks and quick walks, or are they a winter-weather lover who needs an insulated, waterproof option for vigorous romps in the snow and playtime with friends? These answers will guide you in finding the best winter coat for your dog.

Here are some other tips from our veterinarian experts to help you narrow your search.

Fit: Collins also stresses the importance of a good fit. Your dog's coat should be easy to put on, take off, and move around in. He adds that it should strike a balance between not being too loose and not being too tight, so it doesn't restrict movement or irritate the skin. Additionally, consider the overall length and coverage to ensure the coat doesn't get in the way of potty breaks.

Adjustability: Collins says winter coats that can be adjusted in multiple places may work best for dogs with particular body shapes and coat types, like barrel-chested breeds and long-haired dogs. However, he notes that the adjustment points should stay securely in place and not come easily undone under normal use. He adds that the adjustments should also be easy for the person putting on the coat and be well-tolerated by the dog. For instance, an adjustable waistband that's hard to snap shut will be difficult for guardians with mobility issues, while one that clasps loudly might frighten fearful dogs.

Material: The type and quality of a coat's material affect how well it protects against cold temperatures, resists moisture, and blocks strong winds. If you live in a particularly wet, snowy, or windy climate, look for waterproof fabrics like nylon or polyester. For protection against the cold, fleece and polyester are effective insulators, and their soft texture is often comfortable for dogs. Dr. Shelly Vaden, a veterinarian and professor of nephrology and urology at the NC State University College of Veterinary Medicine, recommends looking for reflective materials, like piping and strips, if you walk your dog in heavy-traffic areas.

Design: Winter dog coats vary in design, so check if their features are compatible with you and your dog's lifestyle. For instance, if your dog wears a harness, a coat with a back cutout for a leash is ideal. Or, if you have an especially wiggly pup who struggles to sit still when it's time for a walk, consider a coat with a straightforward closure system instead of an overly complex design with multiple straps, clips, and leg openings. Dr. Alison Meindl, assistant professor of community practice at Colorado State University College of Veterinary Medicine, recommends simpler, faster velcro straps for dogs who may be sensitive to being handled or dislike items being placed over their heads.

Care instructions: Snow, slush, and rain are prime ingredients for a muddy, gritty environment and can quickly soil your dog's coat during walks. To keep a coat clean and prevent bacterial growth that thrives in moist conditions, look for coats made with machine-washable materials. Vaden also recommends choosing a washable fabric that won't shrink since it's important to wash a coat regularly.

How we tested the best dog winter coats

Freelance reporter and professional dog trainer Shoshi Parks originally wrote this guide based on reporting and recommendations from dog walkers across the country. Later, reporter Alex Rennie conducted additional reporting and tested the Petrageous Designs Juneau Coat with his small terrier dog.

Since then, freelance reporter Elizabeth Holbrook has conducted further research, testing new and old options, with her 40-pound rescue mix. Holbrook also looped in Roo's friend Remy, a sheepadoodle of similar size, for extra insight into the Ruffwear Powder Hound Jacket. Additionally, deals editor Sarah Saril tested our large winter coat contender with her 60-pound German shepherd.

Here are the factors we considered in our testing to make our top picks.

Fit: The first thing we did with each coat was check whether the size matched the brand's listed measurements. We also confirmed whether the brand was accurate about sizing up or down when dogs were between sizes. Next, we tried the coats on our dogs to see how easy they were to put on, take off, and adjust. If it was a good fit, our dogs wore the coat on at least two 10-minute walks. While outside, we checked if any part of the coat restricted mobility, caused chasing or discomfort, or interfered with going to the bathroom. We also noted if there were any issues with the leash hole size or placement. Finally, we examined how well the coat's coverage shielded the back, chest, belly, neck, and other key areas from the elements.

Warmth: To test how well the winter coats retained heat, we filled a silicone water bottle with water heated to 100 degrees — similar to a dog's natural body temperature. We then placed the water bottle outside in the cold, with temperatures ranging from 40 to 45 degrees. After 30 minutes, we tested the water with a kitchen thermometer to see how much the warm water had cooled. On average, we discovered the temperature would drop 10 to 13 degrees when the water bottle was exposed directly to the elements. This was our baseline.

We repeated the same steps for each coat: filling the bottle with water heated to 100 degrees, wrapping the coat around the bottle, and leaving it outside for 30 minutes. We then tested the temperature again to see how well it retained the water's warmth in comparison to our baseline and the other coats. Each coat in our guide performed above the baseline, with temperatures only dropping between 3 and 5 degrees.

Durability: Before testing each coat, we carefully examined it for defects or poor construction. To ensure the fabric and hardware could withstand typical dog antics like scraping against trees and bushes, we took a dinner fork, pressed it down forcefully, and scratched each coat. We also tugged on buckles, zippers, and straps and operated zippers and velcro closures at least 20 times.

Waterproofing: For our soak test, we placed a towel inside each coat and let the shower run on it for two minutes. We then let the moisture sit on the coat for half an hour before checking whether the towel and the coat's interior remained dry. We also noted whether the coat was considerably heavier or whether the liner felt cold after being drenched. After conducting our cleaning test, we repeated this step for each coat to assess whether washing affected its waterproofing abilities.

Care: To determine how easy the coats were to clean, we rubbed them with mud and let them sit overnight. The next day, we wiped each muddy patch with a wet cloth to see how easy they were to spot clean. We then followed the label's washing instructions, noting if any required special care.

Dog winter coat FAQs

Should dogs wear coats in the winter?

Anytime you're feeling the cold, there's no harm in putting a coat on your dog, says Dr. Zay Satchu, chief veterinary officer and co-founder of Bond Vet in New York City. "They're more likely to let you know they are feeling toasty by panting than to let you know they are chilly," she notes. Collins adds that a winter coat can help keep a dog dry, protected from the wind, and insulated to reduce heat loss. "Without a coat, some dogs will become uncomfortable and can even be at risk for hypothermia if exposed to the cold for too long," he says. If you're unsure whether your dog is cold, look for indicators like shaking or shivering, a hunched posture with a tucked tail, reluctance to move, and lifting paws while standing in the same position.

At what temperature does a dog need a coat?

"There isn't a specific temperature, but I think it's helpful to consider a coat when the temperature drops below freezing," says Collins. He recommends thinking about other factors as well, like windchill, precipitation, the length of time your dog will be spending outside, and what activity they'll be doing. Dog-related variables, such as breed, size, fur type, and health, will also determine when to don your pup with a cozy coat. Additionally, if it's cold enough that you need to cover every bit of your exposed skin to feel somewhat comfortable, you should stick to bringing your dog outdoors for only quick potty breaks instead of longer walks.

Do dog coats really keep dogs warm?

Yes, a properly fitted coat made with insulated materials can help keep your dog warm by trapping in their body heat. A waterproof outer shell can also block cold water and frigid winds. However, winter dog coats aren't always necessary. Vaden says many dogs do not need coats to keep warm, and even though it may seem cold to us, their natural coats provide adequate protection. "Some breeds will actually develop a thicker coat in the winter to aid in protection from the cold," she says.

What should dogs wear in the snow?

For dogs in the snow for an extended period, Vaden recommends waterproof materials or insulated coats, as well as dog boots to protect their paws. The best dog boots help keep your dog warm and comfortable by protecting their sensitive paws from snow, ice, and salty sidewalks. "Booties are similar to you wearing gloves during the cool months," Satchu says.

What breeds should wear a coat?

"Dogs that more commonly need coats include elderly dogs, dogs that are underweight or have medical problems, dogs with arthritis, small/toy breed dogs, and dogs with short, thin, or clipped coats," says Collins. He adds that dogs closer to the ground, especially long-haired ones, could benefit from a coat to keep their undersides protected from icy water, salt, and snow. On the other hand, double-coated breeds and dogs with thick winter fur, like Siberian huskies and Alaskan malamutes, will have less need for a winter coat. Collins notes that these dogs may even become too warm while wearing a coat in milder conditions or under increased activity.

How to measure your dog for a winter coat

To ensure a proper fit, gather your dog's measurements rather than eyeballing them. Then, cross-reference your measurements with the coat's sizing instructions before ordering. Here are some tips on how to get the sizing right for your dog's winter coat.

Length: Back length is the primary way to determine what size coat your dog will need. Measure your dog while they're standing in a relaxed position from their shoulder blades to the base of the tail. If your dog's measurements are between sizes, go with the larger option, unless the brand says otherwise. Sometimes, a brand will also suggest a specific size based on breed or weight. While this can be helpful, don't use it as your only guide; body types vary drastically among different dogs of the "same" type.

Chest girth: Since most jackets can't be adjusted around the chest, getting this measurement right is crucial, especially for broad or barrel-chested pups. Measure the circumference of your dog's chest at their largest point right behind the front legs while they're standing. Again, go with the larger option if your dog's between chest sizes. If you have an active dog that does a lot of running and jumping, you may want to add another inch or two to ensure they can freely move while wearing the coat.

Neck girth: To get the right fit on a winter coat with a non-adjustable neck opening, measure around the thickest part, right below where the collar sits. As with the other measurements, size up when in doubt.

Drop: Sometimes, a coat will offer a drop measurement. This indicates how low a jacket hangs on your dog's body and legs. If the coat is too long, it may restrict their movement. If it's too short, it may not provide adequate coverage. Ideally, the coat will completely cover your dog's back but extend less than halfway down their leg. To determine how a winter coat will drape across your dog, compare the width of the coat with the distance between your dog's tail tip and their back ankle.
