Quick answer: a dog yeast infection is an overgrowth of Malassezia pachydermatis, a yeast normally present on healthy canine skin. It causes greasy, red, itchy, musty-smelling skin in the ears, paws and skin folds, is confirmed by veterinary cytology, is treated with prescribed antifungals, and is almost always driven by an underlying cause such as allergy. For daily support alongside that care, Pure Majesty Pets Yeast Drops (A$47.00 a bottle) offer a ready-made liquid with caprylic acid, apple cider vinegar and oregano, plus ingredients for skin and digestive support — 19 named actives, roughly 292 mg of active support in every 1 mL, added to food according to the label. Free worldwide shipping — ships to Australia with duties and GST prepaid (DDP), nothing to pay on delivery.

Shop Vet-Strength Yeast Relief →What a dog yeast infection is
A dog yeast infection is an overgrowth of Malassezia pachydermatis, a yeast that already lives on every healthy dog's skin. It shows up as greasy, reddened skin that itches, with a distinctive musty or sour smell — most often in the ears, between the toes, in skin folds, and around the groin. It is not caught from another dog, and in most cases it is a symptom of something underneath it, usually allergy. In Australia it is one of the most common reasons dogs end up at the vet clinic with itchy ears and paws, and it tends to peak in the warm, humid months — summer (December to February) along the Queensland coast and coastal New South Wales, and right through the wet season in the tropical north.
What follows is a triage guide. It tells you what you are probably looking at, whether it can wait until Monday, and what to avoid doing in the meantime. It also covers the Australian side of the problem: why humidity, local grasses and plants matter, which products you will actually find at Petbarn, Pet Circle or your chemist, and where daily internal support such as Pure Majesty Pets Yeast Drops fits alongside your vet's plan.
Key takeaways
- Yeast is already there. Malassezia is a normal resident of canine skin. Disease is overgrowth of a resident organism, not an infection your dog picked up somewhere.
- No photograph diagnoses a dog. Yeast, staphylococcal pyoderma, demodex and contact dermatitis look alike and frequently occur together. Only tape-strip cytology tells them apart.
- Yeast count does not predict itch. Malassezia-specific IgE has been found in roughly 60% of atopic dogs versus 16% of comparison dogs, meaning allergic dogs react strongly to small yeast populations.
- The reference topical is 2% miconazole with 2% chlorhexidine, twice weekly, left on for 10 minutes. Contact time matters more than the brand.
- Skip hydrogen peroxide, tea tree oil, and vinegar on raw skin. A 10-year JAVMA review found 77% of animals exposed to tea tree oil developed an adverse reaction.
- Australian humidity is a real trigger. The WAVD consensus notes that Malassezia dermatitis is more common in tropical climates and in warm, humid months — think a Brisbane or Cairns summer rather than a dry Perth winter.
- Daily internal support helps between baths. Pure Majesty Pets Yeast Drops give 1 mL with food, with every ingredient dose published, for A$47.00 delivered free with duties and GST prepaid.

| Where | What you see and smell | Most likely | Home or vet |
|---|---|---|---|
| Ears | Brown, waxy, coffee-ground discharge. Sweet-sour smell. Head shaking, scratching at the ear base. | Yeast otitis, often on top of allergy | Vet. Nothing goes into an ear before an otoscope confirms the eardrum is intact. More on yeast ear infections |
| Paws, between the toes | Rust or brown saliva staining on pale fur, pink swollen webbing, constant licking, greasy feel. | Interdigital Malassezia, usually allergy-driven | Home care reasonable if skin is intact. Paw yeast guide |
| Belly, folds, armpits | Pink to grey skin, greasy scale, musty smell, darkening over weeks. | Fold dermatitis with yeast overgrowth | Home care plus a vet visit within a week. Belly · Armpit |
| Nail beds | Reddish-brown crust at the claw base, brown nail discolouration, nail chewing. | Yeast paronychia, a strong marker of underlying allergy | Vet. Rarely resolves without treating the driver. Nail bed yeast |
| Lips and chin | Wet, red skin at the lip fold, brown staining, sour odour. | Lip fold dermatitis, often mixed yeast and bacteria | Vet, to check teeth and rule out mixed infection. Lip fold yeast |
| Groin and vulva | Red, moist skin, licking, discharge, odour. | Could be yeast, but urinary disease and vaginitis look similar | Vet. Discharge here needs a urine sample, not a shampoo. Vulvar yeast |
If more than two zones are involved at once, treat that as a systemic signal rather than six local problems. Widespread yeast in an adult dog points to atopic dermatitis, food hypersensitivity, or an endocrine disease such as hypothyroidism or Cushing's.
What it looks like at each stage
Before the descriptions, the honest caveat: no image on the internet, including ours, can diagnose your dog. Malassezia dermatitis, staphylococcal pyoderma, demodicosis and contact reactions overlap visually and frequently coexist on the same dog. The staging below tells you how urgent it is and how long recovery is likely to take. It does not tell you what the organism is. Cytology does that. For the full clinical picture of the skin form, see our guide to yeast dermatitis in dogs.
Early stage
Skin looks slightly pink rather than red. The coat parts easily and the skin underneath feels a little tacky. Your dog licks a paw more than usual, usually in the evening. There may be no smell yet, or only a faint one when you press your nose to the fur. Between the toes, the first visible sign is often rust-coloured saliva staining rather than redness. Caught here, most cases respond to topical treatment within two to three weeks.
Established
The smell arrives. Brown, greasy exudate collects in the folds and between the toes. Skin is clearly red, often with yellowish or greyish scale that flakes off when rubbed. Licking becomes constant and the dog resents handling the area. This is the stage most owners photograph and search. It needs veterinary treatment, and it usually needs the underlying cause investigated at the same time.
Chronic

Skin turns grey-black and thickens into a leathery, ridged texture, called hyperpigmentation and lichenification. Hair thins or disappears. The smell is strong enough to notice from across a room. Chronic changes take months to develop and months to reverse, and some pigment change is permanent. Black spots on the skin at this stage are usually post-inflammatory pigment, not the yeast itself. If the skin has also gone hard and flaking, see crusty skin and what it means.

Yeast, bacteria, allergy or mites?
Photo: Peano et al., 2020, Fig. 3 · CC BY 4.0. Resized for display.
You can read useful clues at home. You cannot reach a diagnosis at home. Here is what is genuinely observable.
| Clue | Yeast | Bacteria | Allergy alone | Mites |
|---|---|---|---|---|
| Smell | Musty, sweet-sour, corn chip | Foul, rotten, sometimes sweetish | Usually none | Usually none |
| Discharge | Brown, waxy, greasy | Yellow, green, creamy, pus | Clear or none | Dry crust, scale |
| Texture | Greasy, thickened over time | Pustules, crusted rings, papules | Red, excoriated from scratching | Scaly, crusty edges |
| Pattern | Folds, warm moist areas, feet, ears | Trunk, often follicular spots | Face, feet, ears, armpits, groin | Ear margins, elbows, hocks |
| Seasonality | Worse in warm, humid months | Not seasonal | Often strongly seasonal | Not seasonal, may affect other pets |
The limit, stated plainly: these categories are not exclusive. A dog with atopic dermatitis commonly has yeast and staphylococcal overgrowth at the same time, with the allergy driving both. A tape strip pressed to the skin, stained with Diff-Quik and read under a microscope gives the answer in under ten minutes: Malassezia appear as peanut-shaped or footprint-shaped budding cells. That test costs little and settles what weeks of guessing cannot.
Two comparisons worth reading in depth: yeast infection versus allergies and yeast versus bacterial ear infections.
The smell decoder
Owners often notice smell before skin change, so it helps to know which smells are normal.
- Corn chips or popcorn, from the paws only, mild, with normal-looking skin. Usually harmless. It comes from ordinary bacteria and yeast living in the moist environment between the pads. No redness, no licking, no action needed.
- Musty or sour, sometimes bread-like, spreading beyond the paws. This is the smell of yeast overgrowth. It gets stronger in humidity and after the dog has been lying down.
- Foul or rotten, sometimes fishy. Think bacterial infection, an anal gland issue, or dental disease rather than yeast.
- Sweet and acetone-like on the breath. Unrelated to skin. This warrants a same-day vet call, as it can indicate diabetic ketoacidosis.
A practical test: wash the area, dry it completely, wait an hour. Normal paw odour fades. Yeast odour returns.
More detail in why your dog smells like yeast.
What not to do
This section exists because these four things appear constantly in online advice and all four can make your dog worse.
Hydrogen peroxide
Hydrogen peroxide is cytotoxic to fibroblasts and keratinocytes, the cells that rebuild skin. It delays wound healing, which is why modern wound-care guidance removed it from open wounds. Yeast dermatitis almost always comes with excoriations from scratching, so the skin you would be pouring it on is exactly the skin that cannot afford it.
One distinction, because it causes confusion: oral 3% hydrogen peroxide is still used to induce vomiting in poisoning emergencies, on veterinary instruction. That is a separate use and says nothing about putting it on skin.
Tea tree oil
The strongest data here comes from Khan, McLean and Slater, JAVMA 2014;244(1):95-99. Reviewing 443 cases reported to a North American animal poison control centre over ten years, covering 337 dogs and 106 cats, they found that 89% of exposures were intentional applications by owners, and 77% of animals developed an adverse reaction: depression, weakness, ataxia and muscle tremors, appearing two to twelve hours after application. The authors concluded that tea tree oil use in dogs and cats is not recommended. Small dogs and any dog that licks the treated area are at highest risk.
Human antifungal medications
Tea tree oil is a familiar bathroom-cabinet remedy in many Australian homes, which is exactly why it ends up on dogs. Keep it in the cabinet, not on your dog's paws.
Never give a human antifungal without veterinary direction, and we will not publish doses. Two specifics worth knowing. Fluconazole, the drug most often found in a human medicine cabinet, has only weak evidence in canine Malassezia dermatitis. Oral nystatin is not absorbed from the gut at all, so it physically cannot reach the skin regardless of dose. There is a broader problem too: repeatedly giving antifungals without addressing the allergy underneath selects for resistant M. pachydermatis, which makes the next flare harder to treat.
Vinegar on broken skin, and anything in a painful ear
Apple cider vinegar is acidic enough to cause chemical burns. Elhage and colleagues (2022) documented burn injury and tissue necrosis from topical application to damaged skin. It may also be ototoxic if the eardrum is perforated, and you cannot see a perforated eardrum from outside. Nothing goes into a painful ear before otoscopy. On effectiveness, two human clinical trials of dilute vinegar returned negative results (Luu and colleagues, 2019; a 2021 PLOS One randomised trial). We would rather tell you that than sell you the idea.
A word on coconut oil
Malassezia is lipophilic. It depends on lipids to grow, because it cannot make its own fatty acids. Applying a heavy oil to affected skin can supply substrate rather than remove it. This is the clearest example of a broader trap: an ingredient that suppresses yeast in a petri dish may do the opposite on a living dog.
For the evidence-weighted version of each popular remedy: home remedies reviewed, apple cider vinegar, and coconut oil.
Why it keeps coming back
Malassezia pachydermatis is a commensal. It lives on healthy dogs, in the ear canals, around the lips, between the toes, and does nothing. Overgrowth happens when the skin's conditions change: moisture, altered lipids, a damaged barrier, or a suppressed local immune response.
The most common drivers, roughly in order: atopic dermatitis and food hypersensitivity; endocrine disease including Cushing's, hypothyroidism and diabetes; concurrent bacterial pyoderma; anatomy such as deep skin folds and pendulous ears; and corticosteroid therapy.
The mechanism behind recurrence is worth understanding. Research using Malassezia-specific IgE testing found the antibody in around 60% of dogs with non-food-induced atopic dermatitis, compared with 16% of comparison dogs. In an allergic dog, the yeast is not simply irritating the skin. It is an allergen. That has two consequences most articles miss. First, the number of yeast organisms on cytology does not correlate with how badly the dog is suffering. A modest population can drive severe itch in a sensitised dog. Second, reducing the yeast population produces temporary relief and reliable relapse, because the sensitisation is still there.
The loop runs like this: allergy causes itch, the dog licks and chews, saliva keeps the skin wet, moisture plus a broken barrier lets yeast multiply, yeast triggers more itch in a sensitised dog, more licking. Any intervention that breaks only one link fails. Controlling the allergy breaks it at the source.
Further reading: why yeast infections recur and yeast flares after antibiotics.
Why Australian dogs flare when they do
Australia gives yeast every advantage it wants: heat, humidity and a long list of plants that irritate skin. Knowing your local pattern helps you get ahead of the next flare instead of reacting to it.
Humidity: Queensland, coastal NSW and the tropical north
The World Association for Veterinary Dermatology consensus (Bond et al., 2020) notes that Malassezia dermatitis is more common in tropical climates and during warm, humid months. In practice that means summer, December to February, is the peak season for most of the eastern seaboard, while dogs in Cairns, Townsville and Darwin can stay at risk for much of the year. Every swim at the beach, every dip in the dam and every summer storm leaves paws, ears and skin folds damp. Dry them properly, especially between the toes and inside floppy ears, and you remove one of the conditions yeast depends on.
Grasses and plants that start the itch
Contact allergy is a common first link in the yeast chain. The Australian Veterinary Association's pet-owner site Vet Voice lists buffalo grass, kikuyu, Wandering Jew, Zebrina, Turtle Vine, Moses-in-a-cradle, Purple Heart and Inch Plant as plants that can cause a red, itchy rash on the paws, belly and armpits — exactly the zones where yeast then takes hold. Wandering Trad (Tradescantia fluminensis) is a particular problem in higher-rainfall NSW, coastal Victoria and south-east Queensland, where it can cause severe allergic skin reactions. If your dog's belly flares every time it lies in one shady corner of the backyard, look at what is growing there.
Pollen seasons differ north and south
For dogs with environmental allergies, the timing of flares often follows grass pollen. According to ASCIA, subtropical grasses in northern coastal areas release pollen mostly from January to March, while southern grasses peak from October to December. A dog in Melbourne that itches every spring and a dog in Brisbane that itches in late summer may have the same disease on a different calendar. Note the months your dog flares — your vet will want that history.
Paws: bindii, heat and licking
Bindii (Soliva) emerges with the May rains and carries spiny seeds until early December; the pods penetrate paws, and a dog that keeps licking a sore foot keeps that foot wet. Hot summer footpaths do the same thing in a different way. The RSPCA recommends walking early or late and using the 5-second hand test on pavement — sore, licked paws are the classic starting point for interdigital yeast.
Skin checks double as tick checks
If you live anywhere along the east coast, from North Queensland to Victoria, the daily skin and ear check you do for yeast is also your paralysis tick check. The RSPCA Australia Knowledgebase advises daily searches for the paralysis tick (Ixodes holocyclus), which is active year-round in the north and from spring to late autumn in the south. Run your fingers through the coat, around the ears and between the toes every evening; you will catch early yeast change and ticks in the same two minutes.
Australia has around 7.4 million pet dogs, with dogs in 49% of households (Animal Medicines Australia, Pets in Australia 2025). Itchy ears and paws are some of the most familiar problems those owners deal with, and a climate-aware routine is the cheapest prevention there is.

What actually works
Topical treatment, the foundation
World Association for Veterinary Dermatology consensus guidance puts topical therapy first for Malassezia dermatitis. The reference regimen is a shampoo containing 2% miconazole with 2% chlorhexidine, applied twice weekly, with a 10-minute contact time before rinsing. The contact time is the part owners skip and the part that matters. A 30-second lather does very little.
Maynard and colleagues (2011), in a 67-dog randomised trial, recorded reductions in yeast counts of at least 88% with this approach. They also found no significant difference between the miconazole-chlorhexidine combination and 3% chlorhexidine used alone, which suggests chlorhexidine is doing much of the work. That is useful to know if your dog reacts to one product.
Oral antifungals, when topical is not enough
For generalised or refractory cases, veterinarians use systemic antifungals. Evidence strength varies and it is worth knowing which is which: ketoconazole and itraconazole carry moderate evidence in canine Malassezia dermatitis, while fluconazole and terbinafine carry weak evidence. These are prescription drugs with liver monitoring requirements and real drug interactions. Dosing belongs with your veterinarian.
Ears

Ear yeast is treated with a medicated otic preparation after otoscopic examination confirms the eardrum is intact. Worth knowing about: DuOtic, combining terbinafine with betamethasone, was approved by the US veterinary regulator on 15 March 2024 as the first otic product for canine Malassezia otitis containing no antibiotic. In Australia, prescription ear medicines must be registered with the APVMA, so ask your vet which antibiotic-free yeast ear options are available here. For a dog with recurrent yeast-only ear disease, avoiding unnecessary antibiotic exposure is a meaningful advantage, and it is worth raising at your next vet clinic visit. Between vet visits, routine cleaning with a vet-recommended cleaner keeps wax and moisture down — Australian options include Dermcare Otoflush (125 mL, A$27.47), Virbac EpiOtic SIS (120 mL, A$23.95 RRP) and PAW Gentle Ear Cleaner (120 mL, A$28.87), or our own vet-strength Dog Ear Cleaner (120 mL, A$43.00).
What you will find on Australian shelves
You do not need to import anything. Medicated shampoos and foams are sold through vet clinics, Petbarn, Pet Circle, Petstock, PetO and many chemists, and your vet can tell you which one suits your dog's skin. A few examples you will recognise:
| Product | Role | Size and price seen (A$) |
|---|---|---|
| Dermcare Malaseb foam | Topical medicated foam — the surface side of the plan, used as your vet directs | 250 mL, A$35.00 (Petbarn) |
| Dermcare Aloveen oatmeal shampoo | Gentle soothing wash for itchy, allergic skin between medicated baths | 500 mL, A$42.95 (Pet City) |
| PAW by Blackmores Dermega Omega 3 & 6 | Oral fatty acid supplement for skin and coat | 200 mL, A$21.00 (Petstock) |
| Dermcare Otoflush | Routine ear flush once the vet has checked the eardrum | 125 mL, A$27.47 (VetShop Australia) |
| Pure Majesty Pets Yeast Drops | Daily oral support for skin, ears and paws at once — 19 named actives, every dose published | A$47.00 per bottle, free shipping, duties and GST prepaid |
The topical products work on the surface, one patch at a time. A fatty acid oil supports the coat but does nothing specific for yeast-prone zones. That gap is why we built a single daily liquid that combines yeast-balancing botanicals, skin-barrier nutrients and gut–skin support — the most complete internal yeast-support formula we know of that publishes every milligram on the label.
The part that determines success
Treating the yeast without identifying what allowed it to overgrow produces a dog who improves for a month and comes back. If this is the second episode, ask your veterinarian about an elimination diet trial, an allergy workup, or thyroid and adrenal testing. Diet is one input among several. See what to feed a dog with yeast issues and foods that tend to make things worse. For a deeper walkthrough of every option above, from medicated shampoos to systemic drugs, read our full guide to dog yeast infection treatment.
Day 7, day 14, day 28
| Checkpoint | What should have changed | If it hasn't |
|---|---|---|
| Day 7 | Less licking and scratching. Odour noticeably reduced. Redness beginning to fade. | Stop and call your vet. No improvement at 7 to 10 days means the diagnosis, the drug, or the contact time is wrong. |
| Day 14 | Greasiness gone. Skin closer to normal colour. Scale reduced. Dog tolerates handling. | Recheck with cytology. Concurrent bacterial infection is the usual explanation. |
| Day 28 | Clinically resolved, or clearly close. Coat regrowing. Pigment change may persist for months, which is expected. | Move the conversation to the underlying cause. Treating flare after flare is not a plan. |
The failure threshold is 7 to 10 days. Getting worse at any point, or no change by day 10, means the situation needs re-evaluating rather than more of the same. See how long a yeast infection typically lasts.
Myths and facts
- Myth: your dog caught it. Malassezia pachydermatis already lives on your dog. Overgrowth is a change in conditions, not transmission. Full explanation here.
- Myth: sugar in food feeds the yeast. Skin Malassezia is lipid-dependent, not sugar-dependent. Diet matters mostly through allergy.
- Myth: more yeast on the slide means a sicker dog. Counts and clinical severity do not track together, because sensitised dogs react strongly to small populations.
- Myth: if it comes back, the treatment failed. Usually the treatment worked and the cause was never addressed.
- Fact: it can affect people, but rarely. M. pachydermatis is documented as a rare opportunistic pathogen in immunocompromised humans, notably in neonatal intensive care via hand carriage. For a healthy adult household the risk is negligible. Wash your hands after treating your dog.
Red flags: call the vet now
Stop home care and contact a veterinarian if you see any of the following.
- Pain, head tilt, loss of balance, flicking eye movements, or apparent deafness, which suggest middle or inner ear involvement
- Bloody or pus-like ear discharge, or an ear too painful to touch
- Skin that is ulcerated, weeping, or bleeding
- Fever, lethargy, loss of appetite, or weight loss
- Increased drinking and urination, symmetrical hair loss, or a pot-bellied appearance, which can indicate endocrine disease
- Any worsening, or no improvement, by day 7 to 10
- Puppies, senior dogs, pregnant or nursing dogs, diabetic dogs, or any dog on immunosuppressive medication should be seen early rather than managed at home
Severe untreated yeast disease is rarely fatal in itself, but it can be a visible sign of a serious underlying illness, and secondary bacterial infection in a compromised dog can become dangerous. More on that in can a yeast infection kill a dog.
What the research does and doesn't show about nutrition
This is the section most brands leave out, so we will be direct about where the evidence runs out.
What research supports. Zinc has a well-described role in canine skin health, zinc-responsive dermatosis is a recognised condition, and zinc contributes to the maintenance of normal skin and coat. Long-chain omega-3 fatty acids have evidence in canine allergic skin disease, where they may support skin comfort as part of a broader plan. Studies of the canine microbiome consistently find lower alpha diversity in atopic dogs than in healthy dogs.
What research does not support, and we will not imply. The microbiome finding is associative, and it concerns atopic dermatitis, not Malassezia overgrowth. Nobody has shown that gut dysbiosis causes yeast overgrowth on skin, or that changing the gut microbiome changes Malassezia populations on the skin surface. Current research does not show that orally administered berberine, oregano extract, or caprylic acid reduce Malassezia on canine skin. Those ingredients have laboratory data showing activity against yeast in culture. A petri dish is not a dog. An oral dose has to survive digestion, reach the bloodstream at a meaningful concentration, and arrive at the skin surface, and for these compounds in dogs that chain has not been demonstrated.
We will also not print a laboratory minimum inhibitory concentration next to our own ingredient list and let you draw the conclusion. Regulators consider that juxtaposition misleading, and it is.
On probiotics. Some products, ours included, use non-living postbiotic yeast cell wall fractions. Studies conducted with live organisms do not transfer to non-living fractions, and citing them would be misleading. We do not cite them. See probiotics and yeast in dogs for the fuller picture.

After the veterinary diagnosis, after the topical plan, and after the underlying cause is being addressed, nutritional support is a supporting role, not a treatment.
Our Pure Majesty Pets Yeast Drops — a support formula, not a substitute for the veterinary care described above — are built on that premise. We publish the full composition with the milligram dose of every one of the 19 active ingredients, which is unusual in this category and deliberate, because most competitors use proprietary blends that hide their doses. Being transparent means telling you that only some of those doses are supported by meaningful evidence. Zinc, at 2 mg per millilitre, contributes to the maintenance of normal skin and coat, and represents a plausible fraction of a 10 kg dog's daily requirement. The wild Pacific salmon oil supplies long-chain omega-3 fatty acids. The remaining botanicals are included at levels well below those used in the laboratory studies they are associated with, and we say so rather than letting a familiar ingredient name do the persuading.
It is formulated to sit alongside your veterinarian's care plan, not to replace any part of it. You can browse the full range of yeast relief for dogs, and if your veterinarian recommends digestive support, our liquid probiotics for dogs delivers 3 billion CFU per serving alongside prebiotic inulin (A$52.00 for 60 mL).
Precautions worth knowing before giving any botanical supplement. Pau d'Arco contains lapachol, which has a warfarin-like anticoagulant mechanism, so avoid it in dogs on anticoagulants, with clotting disorders, or scheduled for surgery. Berberine inhibits CYP450 enzymes and can alter the metabolism of other medications. Botanicals including berberine, licorice, oregano and Pau d'Arco lack safety data in pregnant and nursing dogs and should be avoided there. Supplemental zinc can interfere with copper absorption if your dog receives another mineral supplement. Discuss any supplement with your veterinarian, particularly if your dog takes prescription medication.
How to use Pure Majesty Pets Yeast Drops in Australia
If your vet has confirmed yeast and you want daily support that keeps working between baths and after the course ends — when recurrence actually happens — this is how our customers use Pure Majesty Pets Yeast Drops.

- Dose: shake well, then give 1 mL with food, dosed to your dog's weight as shown on the label. Giving it with a meal supports digestive tolerance.
- Timeline: yeast rebalancing is gradual — use it every day for several weeks and watch for less licking, less odour and calmer skin. Start before your local humid season rather than in the middle of a flare.
- Quality: made in North America in a GMP facility, with a certificate of analysis (COA) on every batch.
- Price: A$47.00 per bottle (was A$68.00), with bundle savings on the product page.
- Delivery: Free worldwide shipping — ships to Australia with duties and GST prepaid (DDP), nothing to pay on delivery.
In Australia, supplements that make no disease-cure claims can fall under the APVMA's Excluded Nutritional or Digestive category, which is why we describe what the drops support rather than promising to cure anything. They are designed to sit next to your vet's plan, never to replace it. For surface relief in yeasty ears, pair them with our Dog Ear Cleaner after your vet has confirmed the eardrum is intact.

Frequently Asked Questions
Can a yeast infection kill a dog?
Very rarely, and almost never directly. Malassezia overgrowth is a skin disease, not a systemic one, in dogs with normal immune function. The danger comes indirectly: severe untreated disease can allow serious secondary bacterial infection, and widespread yeast can be the visible symptom of an untreated endocrine disorder that is itself dangerous. Persistent or spreading disease should be investigated, not endured.
Is a dog yeast infection contagious to other dogs or to humans?
Essentially no. Malassezia pachydermatis is a normal inhabitant of canine skin, so other dogs already carry it. Human infection is documented but rare and confined largely to immunocompromised patients and neonatal intensive care settings, usually spread by hand carriage. Handwashing after treating your dog is sufficient precaution for a healthy household.
Does hydrogen peroxide kill yeast on dogs?
It has antimicrobial activity in a test tube, but it is also toxic to the skin cells that repair damage and it delays wound healing. Because yeast dermatitis usually comes with scratched, broken skin, it is the wrong tool in the wrong place. Use a veterinary medicated shampoo instead.
Can I give my dog Diflucan for a yeast infection?
Only if your veterinarian prescribes it. Fluconazole has weak evidence in canine Malassezia dermatitis compared with ketoconazole or itraconazole, requires dosing by weight and liver monitoring, and interacts with other drugs. Human tablets are the wrong strength and the wrong decision to make alone.
How long does a dog yeast infection last?
With appropriate treatment, mild localised cases usually improve within 7 days and resolve in 2 to 4 weeks. Chronic cases with thickened, pigmented skin take 6 to 12 weeks, and pigment changes can persist longer. No improvement by day 10 means the plan needs revisiting.
Why does my dog keep getting yeast infections?
Almost always because the underlying driver has not been treated, most commonly atopic dermatitis or food hypersensitivity, sometimes hypothyroidism, Cushing's disease, or diabetes. Because Malassezia is a normal skin resident, removing it never removes the conditions that let it overgrow. Recurrence is a signal to investigate the cause, not to repeat the shampoo.
How can I tell the difference between yeast and allergies?
They are usually not alternatives, because allergy is frequently what caused the yeast. Practical clues: yeast brings odour, greasy brown discharge and warm moist locations, while allergy alone tends to be seasonal, itchy without much discharge, and affects the face, feet, ears and armpits. Cytology confirms yeast. The allergy diagnosis takes an elimination diet trial or allergy testing.
Is my dog's ear infection yeast or bacterial?
Brown, waxy discharge that looks like coffee grounds, with a sweet-sour smell, suggests yeast. Yellow or green creamy discharge with a foul smell suggests bacteria. Many dogs have both. Since treatment differs and the eardrum must be checked before anything is instilled, this one genuinely needs a vet visit.
What is the fastest way to get rid of yeast on a dog?
Veterinary confirmation by cytology, then a 2% miconazole with 2% chlorhexidine shampoo twice weekly with a full 10-minute contact time, plus treatment of whatever caused the overgrowth. Skipping the diagnosis to save a week usually costs a month.
Can I soak my dog's paws?
A medicated antifungal foot soak prescribed or recommended by your veterinarian can help, particularly for interdigital yeast, and thorough drying afterwards matters as much as the soak itself. Do not improvise a soak with vinegar or peroxide on skin that is broken or raw.
Why does my dog's yeast get worse in an Australian summer?
Malassezia dermatitis is more common in warm, humid conditions, so flares often peak from December to February along the Queensland coast and coastal NSW, and for much of the year in the tropical north. Swimming, storms and licking keep skin folds, ears and paws damp. Dry your dog thoroughly after every wet outing and check ears and paws daily.
