A wet, windy NZ winter is one thing if you've got a fluffy double-coated dog who treats a sou'wester like a spa day. It's quite another if you're walking a whippet who shivers at the sight of a cloud, or a senior dog whose stiff joints feel every degree the temperature drops. A well-fitted dog coat is the easiest way to keep walks comfortable through the colder months, and we've got more options at Petdirect this season than ever.
Here's a practical NZ guide to the best dog coats for winter, including how to choose between the styles, which type suits which kind of dog, and the brands worth knowing about in our 2026 range.
Quick answer
The right dog coat depends on your dog's coat type, age, and where you walk. For short-haired or thin-skinned dogs, you want a warm, insulated coat. For wet walkers, a waterproof jacket is the priority. For senior dogs with stiff joints, look for a soft, easy-to-fit pullover or sweater that won't fight you on the way in. Newer brands at Petdirect like Dog Friendly Co., Pointer & Hound, Pet One and GF Pet have built specifically for the NZ winter, with Trixie's Norwood pullover a popular soft option and EzyDog's Element coat for general everyday wear.
Does My Dog Actually Need a Coat?
Not every dog needs a winter coat. Heavily double-coated breeds (Huskies, Samoyeds, Alaskan Malamutes, Bernese Mountain Dogs, Border Collies, Golden Retrievers, Labradors) usually have all the insulation they need, and adding a coat can sometimes overheat them. For other dogs, especially those in the categories below, a coat genuinely makes a difference.
Short-haired and thin-coated dogs
Whippets, Italian Greyhounds, Greyhounds, Boxers, Staffies, Dachshunds, French Bulldogs and Chihuahuas have minimal natural insulation. They feel the cold from the moment they walk out the door, and a coat changes the whole experience of a winter walk.
Senior dogs
Older dogs lose body heat faster and their joints stiffen in the cold. A soft sweater or insulated coat keeps them comfortable on walks they'd otherwise want to cut short. Easy step-in or pullover designs are easier on stiff shoulders than complicated harness-style coats.
Puppies and small breeds
Puppies and tiny dogs lose heat fast because of their surface-area-to-body-mass ratio. Coats give them confidence on walks and stop them shivering, which is important for dogs whose energy budget would otherwise go into staying warm.
Dogs with health conditions
Dogs recovering from clinic visits, those with thyroid or coat issues, or dogs on a low body condition all benefit from extra warmth. If your dog has been shaved, the coat acts as a temporary second layer until their fur grows back.
Heavy-rain walkers
Even thick-coated dogs can benefit from a waterproof jacket if your usual walk turns into a wet one. It's less about warmth and more about keeping the coat itself dry, which means less wet-dog smell and a much shorter post-walk towel-off.
City and night walkers
Reflective or high-vis coats add a safety layer during shorter winter days. Most dogs are walking in low light at least one end of the day through June and July, and a reflective coat works alongside lead and collar reflectors to keep them visible.
The Four Types of Winter Dog Coat
1. Waterproof jackets
The workhorse of NZ winter. Waterproof on the outside, often lightly lined inside. Good for any dog who walks in the wet, including heavily-coated dogs who don't need insulation but do need to stay dry. Look for adjustable straps, a back length that covers from collar to base of tail, and good ventilation through the chest.
2. Insulated parkas and jackets
Thicker, warmer, often with a fleece or quilted inner layer. The right pick for short-haired dogs, senior dogs, or any dog who'd otherwise shiver on a winter walk. Most have a waterproof outer too, so they handle a shower as well as the cold.
3. Sweaters, pullovers and hoodies
Soft, easy to put on, brilliant for indoor cool spells, post-bath warming, or short walks where a full waterproof is overkill. The Trixie Norwood pullover is a popular soft sweater, and Dog Friendly Co.'s winter hoodie has a cosy fleece lining. GF Pet's sweater range is great for sizes that don't suit a stiffer coat.
4. Calming and weighted coats
Different category, same shape. Calming coats apply gentle pressure across the body which some dogs find soothing during fireworks, storms, clinic visits or anxious moments. The ThunderShirt is the best-known pick at Petdirect, and a useful winter addition for dogs whose anxiety ramps up with shorter days.
How to Measure and Fit a Dog Coat
Getting the size right makes the difference between a coat that's used every winter and one that sits in the cupboard.
What to measure
- Back length: from the base of the neck (where a collar sits) to the base of the tail. This is the most important measurement.
- Chest girth: the widest part of the rib cage, just behind the front legs.
- Neck girth: around the neck where a collar sits.
- Weight: some brands size by weight rather than measurement, especially for sweaters.
Compare your measurements to the brand's size chart, and if you're between sizes, the right call usually depends on coat type. Insulated coats and parkas tend to fit better in the larger size, since a snug fit on bulky outerwear restricts movement. Sweaters and pullovers tend to fit better in the smaller size, since they should be close to the body rather than baggy.
The fit test
Put the coat on and check three things: can your dog walk normally without restriction? Can you slide two fingers under the strap at the chest and neck? Does the coat cover the back from collar to tail without sitting on the legs? If yes to all three, you've got the right fit.
Matching the Coat to the Dog
Small breeds and toy dogs
A soft sweater or pullover often works better than a stiff coat, since it's easier to put on a wriggly small dog. GF Pet's sweater range and Trixie's Norwood pullover come in small sizes. The Dog Friendly Co. winter hoodie is another easy pick.
Senior dogs
Step-in or pullover designs are kinder than coats with multiple straps. Look for soft inner linings (fleece is ideal) and a back length that fully covers the lower back, where older dogs feel the cold most.
Active dogs and runners
A lightweight waterproof jacket beats anything bulky. The EzyDog Element is a popular all-rounder, and the Pet One Night Walker has reflective trim for low-light running.
Anxious or nervous dogs
If your dog gets stressed by storms, fireworks or unfamiliar situations, a ThunderShirt-style calming coat is worth considering alongside (not instead of) a regular winter coat.
Adventurers and forest walkers
For dogs who walk on rougher terrain, an insulated parka with full back coverage like the GF Pet Elasto-Fit or the Pet One Blizzard handles wind, rain and bramble alike.
City and night walkers
Reflective trim is the standout feature. The Pet One Night Walker and Night Sleeper coats both include reflective detailing, and the Pointer & Hound Waterproof Jacket has a high-vis finish for low-light walks.
Care and Cleaning
Most modern dog coats are machine washable on a cool, gentle cycle, but always check the label. A few tips for keeping a coat working all winter:
Looking after a winter dog coat
- Wash on a cool gentle cycle, no fabric softener. Softener clogs the waterproof membrane.
- Air dry rather than tumble dry where you can, especially on insulated coats.
- Re-proof a waterproof outer once a season with a pet-safe waterproofing spray if water stops beading.
- Brush off mud when dry rather than scrubbing it in when wet. Mud is easier to remove from a dry coat.
- Store the coat away from direct heat (radiators, dryers, sunny windowsills) when not in use to keep elastic and waterproofing in good shape.
Frequently Asked Questions
How do I know if my dog is cold on a walk?
Watch for lifting paws one at a time, shivering, slowing down, tucking the tail, or looking for direction back home. Very short-coated dogs, very small dogs, and senior dogs feel cold sooner than thicker-coated breeds. A well-fitted coat usually sorts it.
Can a coat overheat my dog?
Yes, for thick-coated breeds. If your dog is panting heavily, drooling, or looking flat on a walk in a coat, take it off and reassess. Most coats are designed for short-to-medium-coated dogs, and double-coated breeds rarely need them.
What's the difference between a parka and a jacket?
A parka is heavier, longer and more insulated. A jacket is usually lighter, often waterproof, and offers less warmth on its own. For NZ winters, most dogs are happy in a waterproof jacket. Parkas are best for very cold mornings, senior dogs, or short-coated breeds.
Are sweaters warm enough for outside?
For a short walk on a dry, mild day, yes. For longer walks, wet weather, or very cold days, a waterproof outer over the sweater is better. Sweaters shine for indoor cool spells and post-bath warming.
Do dog coats really need to be waterproof in NZ?
It depends on where you live. If you're in Auckland, Wellington or anywhere with frequent winter showers, yes. If your winter walks are mostly dry and cold (Central Otago, for example), an insulated coat without full waterproofing can be enough.
How do I introduce a coat to a dog who's never worn one?
Let them sniff and explore the coat first. Put it on for short periods inside with lots of praise and treats. Build up to short outdoor walks. Most dogs are wearing a coat happily within a week, especially once they associate it with going out.
What size should I buy if my dog is between sizes?
For insulated coats and parkas, size up. For sweaters and pullovers, size down. Always check the brand's size chart against your dog's back length and chest girth, since sizing varies between brands.
