Looking After Your Dog in Winter
As the chill of winter rolls through Cherrybrook and surrounding suburbs like Castle Hill, Dural and Pennant Hills, many dog owners start to wonder — should my dog be wearing a winter coat? While Australia may not get snow in Sydney, the cooler months can still affect your pet’s comfort and health.
At Cherrybrook Vet, we’ve been fielding more questions than ever about how to keep dogs cosy in winter, especially when it comes to coats, rain protection and seasonal care. Whether your pup is a short-haired Chihuahua or a thick-coated Groodle, understanding your dog’s winter needs is key to keeping them healthy and happy.
In this guide, we’ll help you understand:
- If your dog needs a coat or rain protection
- How breed, age and health affect winter warmth
- Tips for joint health, comfort and enrichment
- Vet-approved advice from our team at Cherrybrook Vet
Does Your Dog Really Need a Winter Coat?
This is the most common question we’re asked, and the answer depends on your dog’s breed, coat, age and environment. While many dogs tolerate cooler weather well, others benefit significantly from added warmth in winter.
According to the RSPCA NSW, some dogs may need extra warmth during colder months, especially small breeds, dogs with short or fine coats, elderly dogs, or those recovering from illness. Sydney’s winter lows can sit between 6°C and 8°C at the beginning and end of the day, cold enough that some dogs, especially smaller breeds, young or older dogs, will feel the chill during early mornings and evening walks.
Our vets recommend:
“If you’re cold, chances are your dog might be too… especially if you notice that they’re shivering or reluctant to go outside.”
Breeds and Ages That Need Winter Coats
- Greyhounds & Whippets: Thin coats and low body fat.
- Chihuahuas & Toy Breeds: Small size = fast heat loss.
- Dachshunds: Popula,r winter coat wearers with short coats and long backs (prone to spinal issues).
- Poodle Crosses (‘Oodles’): Despite curly coats, many oodles have a mix of water-loving breeds (e.g. Labrador x Poodle, Spaniel x Poodle) and may benefit from an extra layer.
- Senior dogs or dogs with arthritis: Benefit from joint warmth.
The keyword here isn’t fashion, it’s function. A dog in a winter coat isn’t just cute; it may be far more comfortable and protected.
Raincoats for Dogs: Are They Necessary?
Sydney’s winter isn’t just cold, it’s wet. June to August typically sees the highest rainfall of the year. For many dogs, wet coats can mean hours of discomfort, or worse, skin irritation and infections.
A good dog raincoat can help keep your dog dry during a wet walk, reducing post-walk shivers and soggy fur all over your home.
Our vets have noticed:
“Long-haired breeds often take hours to fully dry. A raincoat cuts down drying time and keeps them more comfortable.”
When considering raincoats for dogs, think about:
- Fit by breed size: Look for dog raincoats for small dogs, medium dogs, or large breeds like Labradors
- Ease of use: Velcro closures, leash holes, reflective strips
- Coverage: Some coats include belly panels for extra splash protection
Our vets reommend:
“Oodle breeds like Cavoodles, Labradoodles and Spoodles benefit from winter coats because their curly fur can trap moisture, making them colder rather than warmer,” says one of our Cherrybrook vets. “A coat can help them regulate temperature better.”
Choosing Your Dog’s Winter Coat
Whether you’re walking through Cherrybrook Oval or heading to a dog-friendly café in Castle Hill, having the right winter gear can make all the difference. A well-fitted dog winter coat provides warmth without restricting movement, and can also help reduce joint stiffness in cold conditions. Here are some points to consider when selecting the best the best dog winter coat:
Size & Fit
Choosing the right size coat for your dog is essential for comfort, warmth, and safety. Before purchasing, take accurate measurements of your dog’s collar (neck), chest (widest part of the ribcage), and length (from base of neck to base of tail).
Each coat manufacturer uses different sizing standards, so a “Small” in one brand may be a “Medium” in another. Below is a handy diagram to help you get accurate measurements of your dog before buying. Use the table below as a general guide – always refer to the specific brand’s sizing chart before purchasing.
| Size | Collar (cm) | Chest (cm) | Length (cm) |
| XXS | 18–22 | 30–39 | 28 |
| XS | 23–30 | 40–47 | 33 |
| S | 31–38 | 48–56 | 38 |
| M | 39–48 | 57–67 | 43 |
| L | 49–57 | 68–76 | 48 |
| XL | 58–68 | 77–88 | 53 |
Hint
To make reordering or comparing sizes easier, consider saving your dog’s measurements in your phone’s Notes app or Google Keep.
Popular sizes by breed:
- Extra small dog coats for winter – ideal for Chihuahuas, Toy Poodles, and Tenterfield Terriers
- Small dog winter coats – fit Jack Russells, Cavoodles, Dachshunds, French Bulldogs, and Pugs
- Medium winter dog coats – suited to mid-sized Oodles, Border Collies, Staffies, Kelpies, and Cattle Dogs
- Winter dog coats for large or extra-large dogs – perfect for Labradors, Golden Retrievers, larger Labradoodles, Groodles, German Shepherds, and other large breeds
Materials & Cleaning
When it comes to keeping your dog warm, dry and comfortable during the winter months, the material of their coat matters just as much as the fit. Each fabric offers different benefits, so choosing the right one for your dog’s lifestyle and environment can make all the difference. Just like our own jackets, dog coats require specific care to keep them in good shape — and to keep your pup cosy all season long.
Synthetic Fabrics (Nylon or Polyester)
Synthetic materials like nylon or polyester are commonly used in padded dog coats and raincoats. These fabrics are water-resistant or waterproof, windproof, and lightweight, making them ideal for wet winter walks. They are also generally easy to clean — most can be wiped down with a damp cloth or machine-washed on a gentle cycle. However, always check the manufacturer’s label for specific washing instructions, especially if the coat is insulated or has a special waterproof lining.
Care tips:
Avoid using fabric softeners, as they can degrade water-resistant coatings over time. Frequent washing and general use can remove its weather proof surface, so consider applying a waterproofing spray when needed. Make sure the product is safe for close contact with animals.
Polar Fleece
Polar fleece is a popular material for lightweight winter warmth. Soft, insulating, and comfortable, it’s often used on its own for milder days or as a lining in raincoats and waxed coats, as it isn’t waterproof. It’s also ideal for layering under more rugged outerwear on particularly cold or windy days. Many owners appreciate how quickly fleece dries and how well it retains heat — even when damp.
Care tip:
Wash fleece in cold water on a gentle cycle and avoid high heat in the dryer to prevent pilling.
Oilskin or Waxed Cotton
Oilskin or waxed cotton fabrics offer a rugged outer shell that’s perfect for rain, sleet or snow. Originally designed for rural workwear, these coats repel water while remaining breathable and durable. They’re often lined with polar fleece or flannel for added comfort. This combination makes them an excellent all-weather option for active or rural dogs.
Care tip:
These coats should not be machine-washed. Instead, spot clean with a damp cloth and re-wax the outer shell periodically to maintain water resistance.
Synthetic Knits
Knitted coats made from synthetic yarns (like acrylic or polyester blends) are a popular and often affordable option, particularly for indoor wear or mild weather. While they may look cute and cosy, synthetic knits are often loosely woven and not ideal for wind or rain protection. However, they can be used as a warming layer under a waterproof coat for extra insulation.
Care tip:
Hand-wash in cold water or use a delicate machine cycle in a laundry bag. Air dry flat to avoid stretching or misshaping the knit.
Wool and Wool Blends
Wool is a natural, breathable and highly insulating fibre that works beautifully in dry, cold weather. Wool or wool-blend coats, whether knitted or cut from blanket fabric, provide exceptional warmth, making them perfect for older dogs, short-coated breeds, or very chilly days. However, wool is also more delicate and can shrink or felt if washed improperly.
Care tip:
Hand wash in cool water with a gentle wool detergent, or dry-clean if recommended. Always lay flat to dry and reshape as needed.

Design Features
A good dog coat isn’t just about fashion – it’s about function. When choosing a winter or rain coat for your pet, consider these design elements:
Adjustable straps and configurations for a snug and secure fit
Belly straps come in a few variations. A single strap around the belly is quick and easy, but unless the fit is perfect, the coat can shift or roll during play. Cross-over belly straps (which form an ‘X’ under the belly) offer more stability and are ideal for active dogs. Coats with multiple adjustment points (neck, belly, and back) ensure a better fit for dogs with non-standard proportions.
One great example is the range from Lil Cracka. While Cherrybrook Vet isn’t affiliated with this brand, we love supporting independent Australian pet businesses doing great work.
High collars or hoods for extra warmth
Just like us, dogs can benefit from a bit of extra coverage around the neck when the wind picks up or the temperature drops. High collars help keep out drafts and provide added insulation, especially for breeds with long, slender necks like Greyhounds, Whippets, and Italian Greyhounds.
If you’ve ever tried to dress a sighthound, you know the challenge – finding a coat long enough to cover their back without being baggy around the neck and chest. Thankfully, there are companies that specialise in designing coats for these unique body shapes. Annie’s Coats offers well-fitted coats exclusively for Greyhounds, while Fair Dinkum Dogs caters to all sizes and breeds, with styles that offer great coverage and comfort.
Another popular cold-weather accessory is the dog snood. Like a scarf for dogs, snoods keep your pup’s neck and ears warm, especially helpful for short-haired or sensitive breeds. Mila & Me carries a lovely selection, or you can easily make one yourself if you’re handy with a needle and thread, or a pair of knitting needles! There are plenty of free snood patterns online for crafty pet parents.
Reflective strips for safety during evening walks
With winter comes shorter days and earlier dusk, making visibility a real concern during those after-work walks. Coats with built-in reflective strips are a great safety feature, helping cars, cyclists, and other pedestrians see your dog clearly in low light conditions.
If your dog’s favourite coat doesn’t already have reflective features, you can easily add your own. Stores like Spotlight sell iron-on reflective tape, though for synthetic fabrics, sewing the tape on is safer and avoids the risk of melting the material. Reflective vests are another option if you’d prefer not to modify the coat itself. Whatever method you choose, increasing your dog’s visibility during winter walks is a simple way to add peace of mind.

Beyond Coats: Full Winter Dog Care
Looking after your dog in winter goes beyond just clothing. Here are some essential winter warmers every owner should consider:
Indoor Enrichment
Cold weather can reduce walk frequency. Keep your dog mentally and physically stimulated indoors:
- Puzzle feeders
- Hide-and-seek games
- Short training sessions to reinforce commands
Joint Support
Colder temperatures can worsen arthritis, especially in older dogs or long-bodied breeds like Dachshunds.
Our vets recommend joint supplements like glucosamine and chondroitin during winter. Book a winter health check to tailor this to your pet’s needs.
Bedding and Sleeping Areas
Move beds away from cold tiles or drafts. Provide warm, supportive bedding — consider an orthopaedic bed or heated pet mat.
Bathing and Grooming
Keep up with grooming to prevent mats that trap moisture. Limit bathing unless needed, and always dry your dog thoroughly — especially in cooler weather.
Tip:
If your dog must have a bath in winter, try a warm towel wrap afterwards to retain body heat while drying.
Frequently Asked Questions
What temperatures may mean a winter coat is needed for my dog?
As a general rule, when the temperature drops below 10°C, many dogs—especially small, elderly, short-haired or low body-fat breeds—will benefit from wearing a coat. Sydney’s winter mornings often reach 6–9°C, which can be uncomfortable for sensitive dogs. Pay attention to signs like shivering, reluctance to go outside, or huddling for warmth.
Our vets recommend:
“If it’s too cold for you in a t-shirt, it’s probably too cold for your dog without some insulation.”
In what weather conditions is a coat or raincoat recommended?
Raincoats are ideal for wet days, even if temperatures are mild. Keeping your dog dry helps maintain warmth and prevent skin issues or prolonged dampness.
Winter coats are useful on dry but cold mornings or evenings, particularly when there’s wind chill.
Combine a raincoat with a warm inner layer if your dog needs extra warmth and it’s both cold and wet.
If my dog is wet after a walk, what is the best way to dry them?
After a wet walk, drying your dog thoroughly is essential to prevent them from getting chilled — especially in colder weather. Start by using a super-absorbent towel or a designated microfibre dog towel to gently but thoroughly remove as much moisture as possible. Focus on the paws, legs, belly, and ears, which tend to get wettest.
If your dog has a long or thick coat, a pet-friendly hairdryer on a low heat setting can be used, but always keep it moving and at a safe distance to avoid burns. For dogs who love getting muddy or wet regularly, you might consider investing in a drying coat — similar to a wearable towel — which can be a quick and comfortable option for the trip home or after a bath.
Our vets recommend:
“Always make sure your dog is dry before putting them in a coat, as trapped moisture can lead to skin irritation or matting.”
If your dog is regularly wet or dirty after walks, it might be time for a winter wellness check — we’ll check their coat, skin, and overall comfort.
Can dogs catch a cold like we do?
Dogs can’t catch the human cold — and one big reason why is body temperature. A dog’s normal body temperature ranges between 38.3°C to 39.2°C, which is too warm for the human rhinovirus (the virus behind our common cold) to survive or replicate effectively.
However, dogs can get their own version of a cold caused by canine-specific viruses and bacteria, such as canine influenza, parainfluenza, and bordetella bronchiseptica (the bacteria behind kennel cough). These infections can cause symptoms similar to human colds — sneezing, nasal discharge, coughing, and lethargy.
Cold, wet weather doesn’t cause illness by itself, but it can lower your dog’s immune defences, especially in older dogs or those with existing health conditions. That’s why it’s important to keep your dog warm and dry, particularly after walks or during extreme weather.
If your dog shows signs of illness, a quick check-up at Cherrybrook Vet can help diagnose and treat the issue early.

Final Thoughts: Keeping Your Dog Safe and Snug This Winter
As temperatures drop across Sydney and surrounds (Cherrybrook, Castle Hill, Pennant Hills, Dural and beyond) many dogs will benefit from a bit of extra warmth during the colder months.
Not every dog needs a coat, but many do. Breeds like Dachshunds, Poodles, Chihuahuas, Greyhounds and senior dogs are particularly sensitive to cold. And for the ever-popular Oodle breeds, their moisture-retaining curls mean warmth and dryness are key to comfort.
Our vets at Cherrybrook Vet are here to help you tailor your winter care routine to your dog’s breed, age, and health needs.
