If your dog has been scratching, biting, or rubbing their skin constantly since the rains started, you're not imagining it, and you're not alone. Every monsoon season, vet clinics across India see a sharp rise in skin-related consultations for dogs.
The reason is straightforward: India's monsoon creates near-perfect conditions for skin problems. Humidity between 80 to 95%, wet fur that takes hours to dry, muddy walks, and an explosion in the flea and fungal populations, it all hits at once.
Here are the 5 most common reasons your dog is scratching this monsoon, how to tell them apart, and what to do for each.
If your dog is scratching to the point of breaking skin, bleeding, or showing raw patches, see a vet today. This article covers home assessment. Open wounds need to be seen by a vet.
Fungal Skin Infection (Ringworm / Dermatophytosis) Monitor
The most common skin problem in Indian dogs during monsoon. Despite the name, ringworm is not a worm, it's a fungal infection that thrives in warm, humid conditions. Spores that lay dormant in dry months explode in monsoon humidity.
What to look for: Circular patches of hair loss with a raised, reddish ring at the edges. Scaling or crusting skin. Moderate itching, not as intense as flea allergy. Usually appears on the face, paws, or front legs first.
Who's at risk: All breeds, but puppies and older dogs with weaker immune systems are most vulnerable. Indoor dogs that play in parks or contact with other dogs are commonly infected.
What to do: Keep the area dry and clean. Your vet will advise on the right care, which may include a medicated shampoo. Do not share towels or bedding, ringworm is zoonotic (can spread to humans). See a vet for a skin scrape confirmation.
Hot Spots (Acute Moist Dermatitis) Urgent
Hot spots are the monsoon's most painful gift to dogs. A small patch of irritation, from a flea bite, minor wound, or wet fur, becomes a target for frantic licking and scratching. Within 24 to 48 hours, bacteria colonise the site and it becomes a weeping, infected lesion that can grow to the size of your palm.
What to look for: A clearly defined, red, moist, and often smelly lesion. The surrounding fur is usually matted. Your dog will focus obsessively on the spot, licking, biting, and rubbing it against surfaces. Hot spots are painful to the touch.
Who's at risk: Double-coated breeds (German Shepherds, Labradors, Golden Retrievers, Huskies) are most susceptible because their undercoat traps moisture. Long-coated dogs (Cocker Spaniels, Shih Tzus) are also high-risk.
What to do: This is an Urgent result, see a vet same day if possible. Your vet will advise on the right care. Do not cover it with a bandage (it needs airflow), and use an e-collar to stop the licking.
Not sure if it's a hot spot or ringworm?
PawCheck's skin scanner can tell the difference in under 10 seconds. Take a photo of your dog's skin and get a severity result, Normal, Monitor, or Urgent.

Flea populations explode during monsoon. A dog with flea allergy doesn't need dozens of fleas to suffer, a single bite can trigger an intense immune reaction that causes severe, widespread itching lasting days.
What to look for: Intense scratching concentrated at the base of the tail, hindquarters, inner thighs, and belly. Small red bumps or scabs in these areas. You may or may not see actual fleas, check for flea dirt instead (tiny black specks that turn red-brown when wet).
Who's at risk: Any dog not on year-round flea protection. In India, flea protection is often stopped in winter and forgotten, monsoon brings a surge before owners restart.
What to do: Ask your vet which flea product is right for your dog and start it promptly. Clean your home too, flea eggs in carpets and furniture reinfect dogs for months. Your vet will advise on how to settle the allergy reaction itself.
Yeast Skin Overgrowth (Malassezia) Monitor
Malassezia is a yeast that normally lives on dog skin without causing problems. In monsoon humidity, it overgrows and causes a greasy, smelly skin condition that drives dogs crazy with itching.
What to look for: Greasy, yellowish skin especially in skin folds, armpits, groin, between toes, and under the ears. A distinctive musty or corn-chip odour. Darkening of the skin over time. Intense itching, especially in warm areas of the body.
Who's at risk: Breeds with skin folds, Bulldogs, Pugs, Shar Peis, Cocker Spaniels, Basset Hounds. Also common in dogs with allergies (allergic skin breaks down the skin barrier, allowing yeast to overgrow).
What to do: Your vet will advise on the right care, which may include a medicated shampoo. Keep skin folds dry, dry thoroughly after every bath or walk. In persistent cases, your vet will advise on next steps. Check for an underlying allergy triggering the recurring yeast.
Environmental Allergy (Atopic Dermatitis) Monitor
Some dogs are allergic to environmental triggers, grass pollen, mould spores, dust mites, and mud. All of these are at peak levels during monsoon. Atopic dermatitis causes chronic, generalised itching that worsens predictably every year at the same time.
What to look for: Generalised itching, paws, face, ears, armpits, belly, without a specific skin lesion at the source. Recurrent ear infections. Licking or chewing paws obsessively. Symptoms that started predictably 2 to 3 weeks into monsoon every year.
Who's at risk: Genetically predisposed breeds: Labradors, Golden Retrievers, German Shepherds, Beagles, and all Terrier breeds. Atopy typically starts between 6 months and 3 years of age.
What to do: Wipe paws after every outdoor walk to remove allergens. Bathe weekly with a gentle oatmeal shampoo. Your vet will advise on options for season-long control. Allergy testing and immunotherapy is available in metro India for dogs with severe recurring cases.
Quick reference: which cause is it?
Use this guide if you're not sure which of the 5 causes applies to your dog:
- Circular bald patches with a ring edge → Ringworm (fungal)
- Weeping, smelly, localised lesion that grew fast → Hot spot (urgent)
- Intense itching at the tail base and hindquarters → Flea allergy
- Greasy skin, musty smell, skin folds affected → Yeast overgrowth
- Generalised itching, paw chewing, ear infections, seasonal → Environmental allergy
PawCheck tip: More than one cause can be happening at the same time. Flea allergy can trigger hot spots. Atopy can allow yeast to overgrow. If your dog has multiple symptoms from different categories, a vet visit is the fastest path to the right care.
Monsoon skin care checklist
- Dry thoroughly after every walk or bath, use a towel or hair dryer on a cool setting. Wet fur is the primary driver of monsoon skin problems.
- Start flea and tick protection before monsoon begins, the first week of June, not when you first spot a flea.
- Wipe paws before they enter the house, removes mud, allergens, and flea eggs from outdoor surfaces.
- Switch to weekly anti-fungal baths during peak monsoon, using a medicated shampoo only if your vet recommends one.
- Check skin folds daily in fold-prone breeds, moisture trapped in folds becomes an infection within 48 hours.
- Keep bedding dry, wash and fully dry your dog's bed at least once a week during monsoon.
