Why Dogs Get More Hot Spots in Rainy Weather – And How to Protect Your Pup

If your dog seems itchier or more uncomfortable during the rainy season, you're not alone. Many dog parents notice a spike in hot spots when the weather turns wet. But why do dogs get more hot spots in rainy weather? Let’s dive into what’s really going on—and how you can keep your pup happy, dry, and itch-free.

What Are Hot Spots on Dogs?

Hot spots—also known as acute moist dermatitis—are red, inflamed, often oozing skin irritations that can appear suddenly and worsen fast. They’re itchy, painful, and can make your dog absolutely miserable.

Hot spots are usually caused by a combination of moisture, bacteria, and irritation, leading to a cycle of scratching, licking, and infection.

Why Rainy Weather Triggers More Hot Spots

Rainy season brings several dog skin enemies all at once. Here’s how wet weather creates the perfect storm for hot spots:

1. Wet Fur = Perfect Breeding Ground for Bacteria

When your dog gets wet from the rain and doesn’t dry off completely, the trapped moisture on their skin creates a warm, damp environment. This is exactly what bacteria and yeast love—and once they settle in, irritation and infection can begin quickly.

Solution: Always dry your dog thoroughly after walks, especially under the legs, belly, ears, and tail.

2. Increased Allergens and Irritants

Rain stirs up mold, pollen, and other allergens. These can irritate your dog’s skin—especially in breeds that already have sensitive skin or allergies. Add in muddy paws and contaminated puddles, and you’ve got the recipe for a hotspot breakout.

Solution: Rinse your dog’s paws and undercarriage after outdoor adventures, even if they don’t look dirty. Use a mild pet-safe shampoo weekly during the rainy season.

3. More Licking, Scratching, and Chewing

Many dogs hate being wet. That discomfort often leads them to lick or scratch excessively—particularly in places like their flanks, paws, or neck. This irritation weakens the skin barrier and invites infection.

Solution: Watch for early signs of licking or redness. Use a cone, protective clothing, or sprays to stop the itch-scratch cycle early.

4. Humidity = Skin Trouble

Even if your dog doesn’t get soaked, high humidity can still be an issue. Skin stays moist longer, and even tiny scratches or flea bites can quickly turn into infected wounds if bacteria multiply unchecked.

Solution: Keep your home well-ventilated and use a dehumidifier in areas your dog sleeps. Regular brushing also improves air flow through the coat and reduces matting.

5. Dirty Gear and Bedding

During the rainy season, collars, harnesses, and dog beds get damp and grimy. These hold moisture and bacteria close to your dog’s skin, especially in hard-to-reach spots like the neck and belly.

Solution: Wash your dog’s gear and bedding weekly. Dry everything completely before reuse. Rotate gear to allow full drying between outings.

Are Some Dogs More Prone to Hot Spots in the Rain?

Absolutely! Some dogs are more likely to get hot spots than others, especially in wet weather. These include:

• Dogs with thick or double coats (e.g., Golden Retrievers, Labs, German Shepherds)

• Dogs with allergies or sensitive skin

• Dogs prone to anxiety or obsessive licking

• Breeds with skin folds or dense undercoats

If your dog fits any of these categories, you’ll want to be extra cautious during rainy days.

What To Do If Your Dog Gets a Hot Spot

Caught early, hot spots can usually be treated at home—but severe cases may require a vet visit.

When treating hot spots on dogs during rainy weather, keep the affected area dry and well-ventilated at all times. Moisture worsens infection, so avoid walks during heavy rain, and dry your dog thoroughly after going outside—especially behind ears, under legs, and around the neck. Clip surrounding fur to prevent trapped moisture and improve air circulation. Disinfect gear (collars, harnesses, beds) regularly to eliminate bacteria. Use a cone or recovery suit to stop licking, which is more frequent when dogs feel damp. Avoid using heavy creams that trap moisture; opt for vet-recommended sprays instead. 

Vet-Recommended Puainta® Quantum Silver Anti-itch Skin Spray helps soothe, dry out, and heal damp Hot Spots. It deodorizes and helps relieve fungal and bacterial skin infections, relieves itchy skin in cats and dogs, and helps control the spread of lesions.

Moreover, when indoor humidity exceeds 60%, it’s recommended to use a dehumidifier to support your dog’s recovery from hot spots.

Why Is 60% the Key Threshold?

• Humidity above 60% creates an ideal environment for bacteria, yeast, and mold—all of which can worsen skin infections.

• High humidity keeps your dog’s fur and skin damp for longer, slowing down healing and promoting further irritation.

• For dogs with hot spots, excess moisture increases itchiness and licking, making inflammation worse and expanding the affected area.

Pro Tip:

• Maintain indoor humidity between 45% and 55%—the optimal range for skin healing.

• Use a hygrometer to monitor humidity levels, especially during rainy seasons or in coastal, humid regions.

• Take photos of the spot daily. If it worsens or doesn’t improve within 48 hours, call your vet.

How to Prevent Hot Spots in Rainy Weather

Here’s your rainy-season hot spot prevention checklist:

✅ Towel-dry your dog thoroughly after every outing
✅ Brush your dog regularly to prevent matting and trapped moisture
✅ Keep bedding, collars, and harnesses clean and dry
✅ Rinse paws and belly after walks
✅ Use an anti-itch spray or medicated shampoo if needed
✅ Keep an eye on early signs: redness, licking, odor, or irritation

When Is Rainy Season? (And Why It Matters for Dog Parents)

Rainy season isn’t the same everywhere—it depends on where you live. But in most regions, there's a predictable time each year when the skies open up and the wet weather rolls in. Knowing when to expect it helps dog parents prepare for hot spot prevention and overall canine care.

Common Rainy Seasons by Region

1. United States (especially Southeast and Northwest):

• Pacific Northwest (Oregon, Washington): October to March is the wettest period.

• Southeast (Florida, Georgia): Rainy season typically runs from May to October, with daily afternoon thunderstorms.

• Midwest/Northeast: More scattered rains, mostly in spring and summer (April–July).

2. South Asia (India, Bangladesh, Nepal):

• Monsoon season begins around June and lasts through September.

• Heavy rains, high humidity, and flooding can be common—ideal conditions for dog skin issues.

3. Southeast Asia (Thailand, Philippines, Indonesia):

• Rainy season usually spans May to October, varying by country.

• Humidity and wet grounds increase risk of skin infections in dogs.

4. United Kingdom & Ireland:

• Rain is common year-round, but October to January tends to be the rainiest.

• Frequent drizzles and damp environments keep coats moist—watch for hot spots!

5. Australia & New Zealand:

• Northern Australia: Rainy season hits in summer (November to April).

• Southern Australia & NZ: Wetter in winter (June to August).

6. Latin America:

• Tropical countries (e.g., Brazil, Colombia): Wet season usually occurs from April to November.

Why Dog Parents Should Pay Attention

Whether you're in humid Florida or monsoonal Mumbai, understanding your local rainy season helps you:

• Prepare your dog’s grooming and hygiene routine

• Stock up on paw wipes, rain gear, and drying towels

• Adjust walk times to avoid the wettest parts of the day

• Monitor your dog’s skin closely for early signs of irritation

Knowing your rainy season means fewer surprises—and fewer vet visits due to skin flare-ups like hot spots.

Rainy weather might bring puddle-jumping fun for your pup—but it also means dog parents need to stay one step ahead. By staying proactive and knowing the signs, you can keep your dog healthy, comfortable, and hot spot-free, no matter how wet it gets outside.
