Quick answer: A dog hot spot, or acute moist dermatitis, is a red, moist, inflamed skin lesion caused by self-trauma from scratching or licking, which lets normal skin bacteria infect the broken surface. Trim the fur, clean and dry the area, stop the licking, deal with the underlying itch trigger, and see your vet if it spreads. To calm the itch that starts hot spots from the inside, give daily Pure Majesty Pets Allergy Relief & Itchy Skin Chews — wild salmon, sardine, chia and borage oils, quercetin, phytoceramides, colostrum and probiotics in one soft chew. A$74, with free worldwide shipping to Australia and duties and GST prepaid (DDP).
Few things are more distressing for a dog owner than watching their pet frantically lick, scratch and chew at a raw, angry patch of skin. If you have ever seen a moist, red lesion appear seemingly overnight on your dog, you have likely met a hot spot. Officially known as acute moist dermatitis, dog hot spots are one of the most common skin complaints vets see across Australia, and they can escalate quickly if left alone.
Whether you're dealing with a sticky Brisbane or Darwin wet season, a Sydney summer of beach swims, the spring pollen surge in Melbourne, or a dry Perth winter, hot spots can affect dogs of any breed in any climate. This guide covers what you need to know about spotting, managing and stopping hot spots coming back, so your dog can find relief fast.
What exactly are dog hot spots?
Hot spots are localised areas of skin inflammation and bacterial infection that develop when your dog's natural skin barrier is broken. They typically start small but can spread rapidly within hours, sometimes growing from the size of a 20-cent coin to the size of your palm in a single day. The affected area usually appears red, moist and inflamed, often with matted fur around it and a noticeable odour.
The condition creates a vicious cycle. Something irritates your dog's skin, so they scratch or lick the area. That breaks the skin surface, allowing bacteria that normally live harmlessly on the skin to invade and cause infection. The infection itches more, which leads to more scratching, and the hot spot grows larger and more painful. Understanding why your dog is so itchy is the first step toward breaking this cycle.
Common causes of hot spots in Australian dogs
Hot spots rarely appear without an underlying trigger. Identifying what started the itch in the first place is crucial for effective management and for stopping repeats. The most frequent causes include:
- Environmental allergies. Grass pollens peak mostly January–March in northern coastal areas and October–December in the south (ASCIA), and many itchy dogs flare right on cue.
- Contact allergies to plants and grasses. The AVA's Vet Voice lists buffalo grass, kikuyu, Wandering Jew, Purple Heart and Moses-in-a-cradle among plants that cause red, itchy rashes on paws, belly and armpits. Wandering Trad (Tradescantia fluminensis), widespread in higher-rainfall NSW, coastal Victoria and south-east Queensland, can trigger severe allergic skin reactions.
- Flea bites. Even a single bite can set off an intense allergic reaction in sensitive dogs, and warm, humid parts of Australia give fleas a long season.
- Food sensitivities, which can trigger outbreaks year-round.
- Moisture. Dogs that swim at the beach or in dams, get caught in summer storms, or aren't dried properly after baths are more prone to hot spots, especially in skin folds and under thick coats. Warm, humid months also favour yeast on the skin (Bond et al., 2020).
- Other itch sources: matted fur, ear infections, anal gland issues, and even boredom or stress.
Breeds with thick double coats like Golden Retrievers, German Shepherds, Labradors and Saint Bernards are particularly susceptible, though any dog can develop them.
One Australian caution: on the east coast, a dog suddenly fixated on scratching around the head and neck deserves a full skin check for paralysis ticks (Ixodes holocyclus). RSPCA Australia advises daily tick searches, and University of Queensland research found 73% of ticks attached to the head and neck. Hind-leg weakness, a change in bark, retching or drooling after a tick bite is an emergency — go straight to a vet.
How to manage dog hot spots at home
If you catch a hot spot early and it is relatively small, you may be able to manage it at home:
- Trim the fur. Carefully clip the hair around the affected area so air can reach the skin and moisture isn't trapped against the wound. Use blunt-tipped scissors or clippers and work gently — the area will be tender.
- Clean it. Use a mild antiseptic solution or diluted chlorhexidine. Avoid hydrogen peroxide or alcohol, which further irritate damaged skin.
- Dry it completely. Pat dry. Keeping the hot spot dry is essential for healing — especially in humid Queensland or coastal NSW weather.
- Apply only what your vet recommends, in a thin layer.
- Stop the licking. An Elizabethan collar (cone) or a soft recovery suit may be necessary for persistent lickers.
Many owners also use soothing products alongside conventional care. Colloidal oatmeal rinses can help calm inflamed skin — Dermcare Aloveen oatmeal shampoo is a familiar Australian option (500 mL, A$42.95 at Pet City). For yeasty, greasy skin, vets often recommend Dermcare Malaseb (250 mL foam, A$35 at Petbarn). Shampoos clean the surface, though — they don't reach the inflammation that drives the itch in the first place. For dogs with recurring skin issues, supporting the skin barrier from within makes a meaningful difference; learn more about how collagen helps dogs with itchy skin.
When to see the vet
Minor hot spots can sometimes be managed at home, but there are situations where professional care is essential. See your vet if:
- the hot spot is larger than a few centimetres across;
- it isn't improving after two to three days of home care;
- your dog has a fever or seems lethargic;
- multiple hot spots appear at once;
- the area has a strong odour or significant discharge.
Your vet may prescribe oral antibiotics, stronger topical medications or anti-inflammatory drugs to bring a severe hot spot under control. They can also help identify the underlying cause, which is key to stopping future outbreaks. In some cases, allergy testing may be recommended to pinpoint specific environmental or food triggers.
Stopping hot spots from coming back
With hot spots, prevention beats firefighting. Regular grooming is one of the most effective measures. Keep your dog's coat clean, dry and free of mats, especially through humid summer months (December–February). After swimming or bathing, dry your dog thoroughly, paying extra attention to areas where moisture gets trapped — behind the ears, under the legs and around the tail.
Keep up a consistent flea and tick routine all year, particularly in the warmer north where parasites are active most months. Work through underlying allergies with your vet, and if your dog flares seasonally, start skin support a few weeks before the pollen season begins. After walks through buffalo grass or kikuyu, a quick rinse and dry of the paws and belly can help contact-allergic dogs.
Nutrition plays a vital role too. A diet rich in omega-3 fatty acids supports the skin barrier and helps calm inflammation. Healthy skin is more resilient against the irritation that leads to hot spots. Our guide on improving your dog's coat and skin health naturally offers practical dietary and supplement tips.
The role of skin supplements in hot spot prevention
The skin is your dog's largest organ and its first line of defence against environmental irritants, bacteria and allergens. When the barrier is strong, it is much more resistant to the kind of damage that leads to hot spots. That's why most chronic itching is best tackled from the inside, not just with sprays and shampoos.
We designed Pure Majesty Pets Allergy Relief & Itchy Skin Chews to work on the whole itch–scratch cycle on three fronts at once:
- Soothe the itch: wild salmon, sardine, chia and borage oils give a deep omega-3 and GLA base, while quercetin — often called "nature's antihistamine" — and bromelain with turmeric (95% curcumin) support a calm inflammatory response.
- Repair the barrier: phytoceramides and biotin help rebuild the skin barrier and strengthen the coat; zinc, vitamin E and rosehip (natural vitamin C) add antioxidant and skin-repair support.
- Steady the gut and immune system: colostrum, probiotics and prebiotics — because a balanced gut is one of the biggest levers on allergic skin.
They're cold-pressed to protect the heat-sensitive oils and probiotics, use a hydrolysed pork-liver base that picky eaters love, contain no artificial flavours or fillers, and come with a Certificate of Analysis on every batch. Most owners look for less scratching and a softer coat across the first 3–6 weeks of daily use.
How they compare with Australian options
| Product | What it is | Australian price |
|---|---|---|
| Pure Majesty Pets Allergy Relief & Itchy Skin Chews | Omega oils + quercetin + bromelain/turmeric + phytoceramides + colostrum + probiotics in one chew | A$74, free shipping, duties & GST prepaid |
| PAW (Blackmores) Dermega Omega 3 & 6 | Omega oil liquid | A$21 for 200 mL (Petstock) |
| Virbac Megaderm | Omega 3 & 6 supplement | 250 mL / 1 L sizes at vets and retailers |
Omega-only oils are a good start, but they only cover one front. Our chews add the antihistamine-style, barrier-repair and gut-immune support in the same daily serving — which is why we call them the most complete itch chew we make.
Collagen is another useful layer for the skin. Our liquid collagen for dogs — the most popular liquid collagen for dogs — delivers 462 mg of hydrolysed collagen types I & III plus 48 mg of UC-II in every 2 mL serving (A$47), supplying building blocks for skin tissue alongside omega fatty acids, probiotics and a balanced diet.
Keep your dog comfortable and itch-free
Hot spots are painful and frustrating, but they are very manageable with the right approach. Understand what triggers them, act quickly when they appear, and invest in your dog's long-term skin health through good nutrition and daily supplementation. Because allergies are the single most common trigger, it's worth reading our guide to the best itch relief for dogs with allergies and our article on a dog constantly scratching and biting himself.

Frequently asked questions
What causes hot spots in dogs?
Hot spots begin with an itch trigger such as allergies, flea bites, trapped moisture, matted fur, ear infections or stress. The dog scratches or licks, breaking the skin barrier and letting normal surface bacteria invade. That infection itches more, fuelling a cycle that can enlarge the lesion within hours.
How can I manage a dog hot spot at home?
For a small, early hot spot, gently trim surrounding fur, clean with a mild antiseptic or diluted chlorhexidine, and pat completely dry. Avoid hydrogen peroxide or alcohol. Stop the licking, using an Elizabethan collar if needed. Ask your vet before applying any medicated product or if the area does not improve.
When should I take my dog to the vet for a hot spot?
See your vet if the hot spot is larger than a few centimetres, fails to improve within two to three days, has a strong odour or discharge, or if your dog develops a fever, seems lethargic or has several lesions at once. These signs may need prescription antibiotics or anti-inflammatory care.
Can supplements help stop hot spots coming back?
Supporting the skin barrier may reduce recurrence. Omega-3 oils, quercetin, phytoceramides and probiotics support a calm skin and immune response, and hydrolysed collagen supplies building blocks for skin tissue. Supplements complement, but do not replace, veterinary care and flea prevention, so talk to your vet about your dog's routine.
Do Pure Majesty Pets itch chews ship to Australia?
Yes. Shipping is free worldwide, and Australian orders arrive with duties and GST prepaid (DDP), so there is nothing to pay on delivery. The Allergy Relief & Itchy Skin Chews are A$74.
