Best Dog Sweaters of 2026: Warm, Washable Picks for Small, Large and Short-Haired Dogs

Best dog sweaters of 2026 at a glance

Frisco is Chewy’s house brand, which is why it keeps winning on price: most Frisco knits land well under $20, Gooby fleece sits in the same range, and Chilly Dog’s hand-knit wool is the premium tier at roughly two to three times that. Prices move by size and season, so check the current listing before you buy.

Does my dog actually need a sweater?

Some do, most don’t, and the dog tells you. Dogs that benefit: short-coated breeds (Chihuahuas, Italian Greyhounds, Boston Terriers, Pit Bulls, Boxers), toy breeds with little body mass, seniors, thin dogs, puppies, and dogs recovering from illness or with arthritis. Dogs that don’t: double-coated northern breeds (Huskies, Malamutes, Samoyeds), Newfoundlands, Bernese Mountain Dogs and most Retrievers, who already wear a sweater. The rough temperature rule vets use: above 45°F almost no dog needs a layer; between 32°F and 45°F, small, thin and short-haired dogs benefit; below 32°F they need one, and below 20°F even hardy dogs should keep walks short. Signs your dog is cold: shivering, a tucked tail, lifting paws, slowing down, or trying to turn home. If you see those, it’s sweater weather for that dog regardless of the thermometer.

How to measure a dog for a sweater

Three numbers, and the chest is the one that matters. Back length: base of the neck (where the collar sits) to the base of the tail. Chest girth: around the widest part of the ribcage, just behind the front legs. Neck: where the collar sits. Compare all three against the brand’s chart, and when the chest and length point to different sizes, size for the chest and accept a slightly shorter or longer back. The fit you want is snug enough that two fingers slide under it, loose enough that the front legs move freely. Too loose and the dog steps out of it or gets a leg through the neck hole; too tight and it rubs the armpits raw. Every Frisco sweater we looked at had reviewers saying it ran either small or large, so measure rather than guessing from your dog’s weight.

Frisco Ultra-Soft Marled Turtleneck Best overall

A thick, soft, marled acrylic knit with a fold-over turtleneck, cut as a simple pullover. No buttons, no zippers, no Velcro to catch fur. It’s warm enough for a cold walk, soft enough that dogs who hate clothes tend to forget they’re wearing it, and it goes in the washing machine. The two knocks: it runs large, so size down if your dog is between sizes, and there’s no leash hole, so you’ll clip to a harness over the top or pull the collar out through the neck. At Frisco prices, buy one in each of two sizes and return the one that doesn’t fit.

Chilly Dog Boyfriend Sweater Best wool

Chilly Dog sweaters are hand-knit by artisans in South America from wool colored with plant-based dyes, and they look like it, in a good way. The Boyfriend is a chunky cable knit in seven sizes from XX-small to XXX-large, one of the few knits that fits an 80 lb dog properly. Wool breathes, resists dirt and stays warm when damp, which acrylic doesn’t. Downsides: no leash hole, it can stretch over a season, and a small number of dogs find wool itchy. If your dog has skin allergies or hot spots, stick with acrylic or fleece.

Gooby Stretch Fleece Vest Best for dogs that hate getting dressed

If dressing your dog is a wrestling match, this is the answer. It’s a stretchy fleece vest you pull over the head and two front legs in one motion, with no fasteners at all. Sixteen colors, machine washable, holds its shape after washing, and the largest size fits dogs up to about 100 lb. It’s lighter than a knit, so it’s an indoor and mild-weather layer rather than a blizzard coat. No leash hole, so pair it with a harness. It’s also a good first sweater for a puppy, because the stretch is forgiving while they grow.

Frisco Buffalo Plaid Best with a leash hole

A classic red plaid V-neck knit with a reinforced leash hole at the back of the neck, so you can clip to a collar without fishing it out. Sizes run from X-small to XXX-large but tend small, so size up. Reviewers wish it were thicker, which is fair: it’s a cool-day sweater, not a deep-winter one. The Frisco Bobble-Knit Turtleneck is the alternative if you have a male dog; its belly is cut higher so bathroom breaks don’t soak the hem, and it also has a leash hole.

Sweater on, collar and tag still on

Winter is the season sweaters hide collars. Don’t let the tag hide too: a sweater with a turtleneck covers the ID, and a sweater with a leash hole lets you pull the collar and tag through so they’re visible. A dog that slips a harness in the snow is a lost dog in the dark, and our lost pet statistics show fewer than a quarter of lost dogs without ID make it home. A Shiloh’s House smart tag has no battery to die in the cold, and anyone who finds your dog can tap it with a phone and call you on the spot. Pair it with a reflective collar for dark winter walks; we rated those in best LED dog collars.
