Dry and Itchy Skin in Dogs This Winter: Causes and How to Help
Why winter dries out your dog's skin
If your dog has been scratching more than usual lately, the season itself may be partly to blame. Cold outdoor air holds less moisture than warm air, and when dogs move between chilly conditions and heated indoor environments, the repeated shift strips natural oils from their skin and coat. According to the Australian Veterinary Association (AVA), environmental factors — including temperature and humidity — are among the most common triggers for skin changes in companion animals, and winter routinely brings a noticeable uptick in dry-skin presentations at vet clinics.
Heating systems are a surprisingly big contributor. Ducted gas heating and reverse-cycle air conditioning both reduce indoor humidity significantly, leaving a dog's skin in an environment that is drier than most Australian summers. Breeds with shorter single-layer coats — such as Whippets, Boxers, and French Bulldogs — tend to show symptoms sooner, though double-coated and long-haired breeds are not immune.
Key insight: It is not just the cold that dries your dog's skin — it is the contrast between dry heated air indoors and cold air outdoors, repeated daily, that gradually depletes the skin's lipid barrier.
Signs your dog's skin needs attention this season
Knowing what to look for helps you act early before mild dryness becomes a more persistent problem. Common signs of winter-related skin dryness include:
- Increased scratching, licking, or chewing — particularly at paws, belly, or flanks
- Visible flaking or dandruff on the coat or on surfaces where your dog rests
- A dull, brittle coat that lacks its usual sheen
- Dry, cracked skin around the nose, paw pads, or elbows
These signs on their own are not necessarily cause for alarm. However, if scratching is intense, skin appears red or broken, or you notice hair loss, odour, or thickened patches, a visit to your vet is warranted — as these can point to an underlying condition rather than straightforward seasonal dryness. Our article on understanding skin allergies in dogs and cats covers the overlap between allergy-driven and environment-driven itchiness in more detail.
Practical tips to support your dog's coat and skin in winter
Most mild winter dryness responds well to a few consistent adjustments at home. The following approaches are broadly supported by veterinary guidance — always confirm with your own vet before making significant changes to your dog's routine or diet.
Grooming and bathing
- Brush regularly (2–3 times per week for most breeds) to distribute natural skin oils and remove dead skin cells
- Use a gentle, soap-free, pH-balanced dog shampoo — human shampoos can disrupt a dog's skin barrier, which has a different pH to ours
- Limit baths in winter and follow each one with a thorough dry to prevent chilling
Nutrition and hydration
Omega-3 and omega-6 fatty acids play a documented role in maintaining the skin's lipid barrier and coat quality. These can be found naturally in quality fish-based dog foods, or discussed with your vet as a supplement option. The best and worst foods for dogs and cats is a useful starting point for understanding how diet affects your pet's skin and coat from the inside out.
Ensure fresh water is always available — dogs drink less in cold weather but hydration still supports healthy skin.
Environment
- Place a humidifier in rooms where your dog spends most time to offset heating-related air dryness
- Provide a warm, draft-free bed away from direct heater vents, which can be drying and overheating for skin
- Protect paw pads on cold or frost-covered surfaces with dog-safe paw balm if recommended by your vet
Bottom line: Small, consistent changes to grooming, diet, and the home environment make the biggest difference to a dog's winter coat condition — no single product is a substitute for a well-rounded routine.
When itching signals something more serious
Seasonal dryness and an underlying skin condition can look very similar from the outside. If your dog's scratching does not improve within a couple of weeks of adjusting their routine, or if any of the more concerning signs below appear, book a vet appointment rather than waiting.
| Sign | Why it matters |
|---|---|
| Hot, red, or oozy skin | May indicate a secondary bacterial or yeast infection |
| Hair loss in patches | Could signal mange, ringworm, or hormonal condition |
| Scratching localised to ears | Often a separate ear-infection issue, not general dryness |
| Sudden onset after diet change | Possible food sensitivity or allergy reaction |
| Symptoms appearing in dogs under 3 years | Atopic dermatitis (environmental allergy) frequently presents young |
For dogs whose itching persists or worsens, a vet may recommend a skin scraping, allergy testing, or a therapeutic diet trial — all of which require professional diagnosis. If telehealth feels like an easier first step, our piece on veterinary telehealth walks through what an online vet consultation can and cannot assess, and when an in-person visit is non-negotiable.
Key insight: Skin conditions are one of the most common reasons Australian dogs visit the vet year-round. Catching a problem early — before secondary infections develop — typically means simpler, shorter treatment.

FAQ
Why does my dog get itchy skin every winter in Australia?
Cold outdoor air is low in humidity, and indoor heating systems reduce humidity further. The daily shift between these two environments strips natural oils from your dog's skin, leading to dryness, flaking and increased scratching. Short-coated and senior dogs may be more susceptible, but it can affect any breed.
Can I moisturise my dog’s dry skin at home?
Some dog-safe topical balms (particularly for paw pads and elbows) are available and widely used. However, it's best to consult your vet before applying any product to your dog's skin, as some human moisturisers contain ingredients that are unsafe for dogs or can worsen the problem.
Does diet affect my dog’s skin condition in winter?
Yes. Omega-3 and omega-6 fatty acids, found in fish-based foods and some supplements, are associated with maintaining the skin's lipid barrier and coat quality. Speak to your vet before adding supplements to your dog's diet to ensure appropriate type and dosage.
When should I take my dog to the vet for winter skin issues?
If your dog's scratching is intense, skin appears red, broken or oozy, you notice patchy hair loss, or home adjustments haven't helped after a couple of weeks, book a vet visit. These signs can indicate infections, allergies or other conditions that need professional diagnosis.
Does indoor heating make my dog’s skin worse in winter?
It can. Ducted gas heating and reverse-cycle air conditioning both significantly reduce indoor humidity, drying the air your dog lives in for many hours each day. Placing a humidifier in rooms your dog frequents and keeping beds away from direct heater vents can help offset this effect.
