How to Prevent Hot Spots on Dogs in Summer: Grooming + Drying Plan

Why Summer Hot Spots Happen (And Why Grooming + Drying Works)

Hot spots (also called acute moist dermatitis) are those suddenly angry-looking patches of red, oozing, itchy skin that seem to appear overnight. Summer is peak season because heat, humidity, swimming, sweaty undercoats, and bugs create the perfect “wet + trapped + irritated” environment.

Here’s the simple truth: most summer hot spots start when moisture and heat get trapped against the skin—usually under a dense coat, behind ears, in skin folds, or where a dog keeps licking. Grooming helps by removing mats and excess undercoat so air can reach skin. Drying helps by eliminating the damp “incubator” that bacteria and yeast love.

If you’re searching for how to prevent hot spots on dogs in summer, the best results come from a system, not a single product:

• •A grooming routine that reduces moisture-trapping coat issues
• •A drying plan for after swimming, baths, rain, or heavy panting
• •A quick “early detection” check so small irritation never becomes a full hot spot

This article gives you a practical plan you can follow all summer.

What Counts as a “Hot Spot” (And When It’s Not One)

Hot spots usually look like:

• •A sudden, raw, wet patch (often circular)
• •Hair matted around it from licking or moisture
• •Strong itch (dog can’t stop scratching/chewing)
• •Sometimes a smell (bacteria/yeast), and warm skin

Common locations:

• •Behind ears (especially after ear infections or swimming)
• •Cheeks/neck (from scratching at itchy ears or collar friction)
• •Under collar/harness areas
• •Armpits/groin/belly (thin skin + humidity)
• •Base of tail/hips (flea allergy zone)
• •Between skin folds (bulldogs, pugs)

Hot Spot vs. Something Else

It matters because prevention is different.

• •Ringworm: often dry, circular hair loss; not usually wet/oozing early.
• •Mange: widespread itch, crusting, thinning; not typically a single wet lesion.
• •Yeast dermatitis: greasy coat, chronic odor, brown staining; more gradual.
• •Allergy flare: red paws, ear issues, belly rash; can trigger hot spots secondarily.

If a patch is rapidly spreading, painful, has pus, or your dog seems unwell (fever, lethargy), skip home care and call your vet. Prevention is the goal—but some cases need medical treatment fast.

The Summer Hot Spot Risk Map: Breeds, Coats, and Real-World Scenarios

Some dogs are simply built to trap moisture. Breed isn’t destiny, but it changes your summer plan.

High-Risk Coat Types (With Breed Examples)

• •Double-coated shedders (dense undercoat holds water):

Labrador Retriever, Golden Retriever, German Shepherd, Husky, Akita

• •Thick, “cottony” coats prone to matting:

Bernedoodle, Goldendoodle, Sheepadoodle, Poodle mixes (matting can seal moisture to skin)

• •Long-coated, feathered breeds (water clings to fringe):

Cocker Spaniel, Cavalier King Charles Spaniel, Setter

• •Skin folds + short coats (humidity in creases):

English Bulldog, French Bulldog, Pug, Shar-Pei

• •Allergy-prone breeds (itch starts the licking cycle):

Westie, Boxer, Pit Bull–type dogs, Bulldogs, Retrievers

Real Scenarios That Commonly Trigger Hot Spots

• •“He swam at the lake and was ‘mostly dry’ when we left.”

Undercoat stays damp for hours—especially over hips, neck ruff, and behind ears.

• •“She got rained on during a walk and towel-dried at home.”

Towels remove surface water but don’t dry the skin line in dense coats.

• •“He’s wearing a harness all day for hikes.”

Friction + sweat + trapped heat under straps.

• •“She has chronic ear gunk and scratches a lot.”

Ear irritation leads to head shaking/scratching, which inflames skin and triggers hot spots on cheeks/neck.

Hot spot prevention is about interrupting these predictable chains.

The Prevention Blueprint: Your Grooming + Drying Plan (The “GDD” Routine)

Think of this as your summer maintenance system:

1. Grooming keeps air moving and prevents mats from sealing in moisture
2. Drying removes the wetness that feeds bacteria/yeast
3. Detection catches early irritation before it explodes

Your Weekly Rhythm (Most Dogs)

• •Daily (2–3 minutes): quick skin/coat check + targeted brush on problem zones
• •2–4x/week: full brush-out (more often for heavy coats or doodles)
• •Every swim/bath/rain: structured drying routine (yes, every time)
• •Every 2–6 weeks: professional grooming or at-home trim/maintenance depending on coat type

If you do only one thing: dry to the skin line after water exposure. It’s the biggest difference-maker.

Grooming Plan: Reduce Moisture Traps Without Damaging the Coat

Step-by-Step: The Summer Brush-Out (10–20 minutes)

This is ideal for Labs, Goldens, Shepherds, collies, and most double coats.

1. Start with a dry coat. Brushing wet hair can pull and break it, and mats tighten when wet.
2. Line-brush or section the coat. Lift layers so you reach the undercoat, not just the top.
3. Use the right tool for the job:

• •Slicker brush for surface tangles and light mats (great for doodles/feathering)
• •Undercoat rake for thick undercoat (great for retrievers/shepherds)
• •Greyhound comb (metal comb) to confirm you’re actually detangled

4) Focus on “hot spot zones”:

• •Behind ears
• •Neck ruff and collar area
• •Armpits
• •Groin/belly fringe
• •Base of tail
• •Between toes (especially after hikes/swims)

5) Finish with a comb check. If the comb snags, moisture can get trapped there later.

Pro-tip: If you can’t easily run a comb through behind the ears and in the armpits, your dog is one swim away from a hot spot.

Mat Management: The Rule That Prevents Skin Blow-Ups

Mats are moisture vaults. They hold water against the skin and create micro-inflammation.

Common mat “hot spot starters”:

• •Doodle armpits
• •Behind ears on spaniels
• •Feathering on legs after beach days
• •Collar mats on long coats

What to do:

• •Small, early mats: carefully split with fingers + slicker + comb
• •Tight mats close to skin: don’t yank; this can bruise skin and trigger licking
• •When in doubt: book a groomer—shaving a mat is safer than ripping skin

Should You Shave a Double-Coated Dog in Summer?

This is where people accidentally increase hot spot risk.

• •Full shaving (down to skin) can cause:
• •sunburn
• •coat texture changes
• •compromised temperature regulation
• •itch as hair regrows (which can trigger licking)

Better options for double coats:

• •Professional de-shed (removes loose undercoat)
• •Neaten trims around:
• •paw pads
• •sanitary area
• •belly fringe (light tidy, not naked skin)
• •behind ears if needed

For poodles/doodles, a shorter summer clip can help if it’s done well and maintained—because these coats mat easily and mats are worse than a shorter cut.

Drying Plan: The Non-Negotiable Step After Swimming, Baths, and Rain

Most “I don’t know how this happened” hot spots are really “the undercoat stayed damp.”

The Gold Standard: Dry to the Skin Line

Towel-drying alone usually isn’t enough for:

• •Labs/Goldens
• •Huskies
• •Shepherds
• •Newfoundlands
• •Doodles with thick coats

You want the skin to feel dry when you part the hair.

Step-by-Step: After-Swim or After-Bath Drying (15–30 minutes)

1. Squeeze, don’t rub (first pass). Use a towel to press and squeeze water out. Rubbing tangles and increases mats.
2. Towel swap (second pass). A second dry towel pulls out significantly more moisture.
3. Target the danger zones first:

• •Behind ears (water runs down and sits here)
• •Neck/chest ruff
• •Armpits and groin
• •Base of tail and hips
• •Between toes and paw pads

4) Use airflow to finish (best option).

• •High-velocity dryer (pet dryer) is most effective for thick coats
• •If using a human dryer: use cool/low heat, keep it moving, avoid overheating skin

5) Confirm dryness with a “part check.” Part hair at the hips and behind ears. If the skin feels cool/damp, keep drying.

Pro-tip: If your dog is “dry on top but damp underneath,” bacteria are already celebrating. Keep drying.

Product Recommendations: Drying Tools That Actually Help

You don’t need a professional setup, but the right tools save time.

• •Highly absorbent microfiber dog towels

Better than bath towels for pulling water out fast (especially on feathering).

• •Pet-safe high-velocity dryer (HV dryer)

Best for double coats; it blows water out of the undercoat. Look for adjustable speed and noise control if your dog is sound-sensitive.

• •Drying robe (for calm dogs)

Works well as a bridge after towel drying, especially for spaniels or small breeds. Not a substitute for airflow on dense undercoats.

• •Absorbent paw towel + paw pad drying

Prevents interdigital irritation after wet grass, beach, or puddles.

If Your Dog Hates Dryers: Low-Stress Alternatives

Many dogs fear the noise/air pressure. You can still prevent hot spots.

• •Start with towel training: reward calm standing + gentle squeeze-drying
• •Use a dryer on the lowest setting from a distance, paired with treats
• •Dry in short sessions: 2 minutes, break, repeat
• •Consider a happy hoodie (ear cover) to reduce noise stress
• •Work with a groomer who offers fear-free handling

Even partial airflow drying is better than none—especially behind ears and at the hips.

Bathing Strategy: Clean Skin Without Over-Drying (Or Leaving Residue)

Bathing can prevent hot spots or trigger them depending on technique.

How Often Should You Bathe in Summer?

General guide:

• •Every 2–4 weeks for most dogs
• •Weekly only if your dog has allergies, swims constantly, or gets greasy—and you use the right products
• •Always rinse extremely well; residue causes itch

Shampoo + Conditioner: What to Look For

Product choices depend on your dog’s skin.

Good summer-friendly options (categories, not brand promises):

• •Gentle, fragrance-light shampoo for routine cleaning
• •Chlorhexidine-based shampoo for dogs prone to bacterial hot spots (ask your vet if frequent use is appropriate)
• •Antifungal (miconazole/ketoconazole) combo if yeast is a recurring problem (again, vet guidance helps)
• •Light conditioner for long coats to reduce tangling (tangles become mats; mats trap moisture)

Comparison: chlorhexidine vs. “natural” shampoos

• •Chlorhexidine: evidence-based antibacterial; can be drying if overused; best for recurrent issues
• •Natural/oat-based: soothing for mild itch; may not control bacterial flare-ups if your dog is infection-prone

The Rinse Rule (Most People Miss This)

Rinse time should be longer than wash time.

• •Thick coats hold suds deep near skin
• •Residual shampoo = itch = licking = hot spot

Practical test:

• •Keep rinsing until the water runs clear
• •Then rinse another 60 seconds in the neck/hips/armpits zones

Targeted Summer Haircuts and Hygiene Trims (By Coat Type)

A smart trim plan prevents moisture traps without damaging coat health.

Double-Coated Dogs (Labs, Goldens, Shepherds)

Best approach:

• •De-shed + tidy
• •Trim paw pads (reduces wet grass irritation)
• •Light tidy of belly/feathering if it drags through water

Avoid:

• •Close shave to skin (increases sun risk; can trigger itch and skin irritation)

Doodles and Poodles (High Mat Risk)

Best approach:

• •Choose a manageable length you can comb to the skin consistently
• •Schedule grooming every 4–6 weeks in summer (more often for swimmers)
• •Keep armpits, ears, and sanitary area very well maintained

Avoid:

• •Keeping the coat long “for looks” while skipping comb-throughs

This is one of the fastest paths to a hot spot.

Bulldogs, Pugs, Shar-Pei (Fold Care)

Best approach:

• •Trim isn’t the main tool—drying folds is
• •Keep skin folds clean and dry; use vet-approved wipes if needed
• •Watch for moisture trapped in facial wrinkles after water drinking or drooling

Early Detection: Catch the “Pre–Hot Spot” Before It Erupts

Hot spots often give subtle warnings 12–48 hours before they look dramatic.

Your 2-Minute Daily Summer Check

Run your hands and eyes over:

• •Behind ears (look for dampness, redness, odor)
• •Collar/harness lines (friction + sweat)
• •Armpits and groin (humidity pockets)
• •Base of tail (flea allergy area)
• •Between toes (sand, burrs, wet grass irritation)

Red flags:

• •Your dog suddenly fixates on licking one spot
• •Hair feels clumpy or sticky
• •Skin looks pink, warm, or bumpy
• •A new odor (yeast/bacteria smell)

What to Do at the First Sign (Prevention Mode)

If you spot mild redness but no open wound:

1. Stop licking (cone or inflatable collar if needed)
2. Clip hair carefully around the area (if you can safely do so without nicking skin) so air can circulate
3. Clean gently with a vet-recommended antiseptic wipe/solution
4. Dry thoroughly
5. Recheck in 6–12 hours

If it’s worsening quickly, oozing, very painful, or spreading: call your vet.

Pro-tip: The cone isn’t “overreacting.” Licking turns mild irritation into a full hot spot faster than almost anything.

Common Mistakes That Cause Summer Hot Spots (And What to Do Instead)

Mistake 1: “He Air-Dried After Swimming”

Air-drying traps moisture under dense coat layers.

Do instead:

• •Towel squeeze + airflow dry + part-check at hips/neck

Mistake 2: Shaving a Double Coat to “Keep Cool”

Shaving can increase sunburn and skin irritation and may not reduce internal heat risk the way people think.

Do instead:

• •De-shed + brush-out routine + cool surfaces + hydration + shade

Mistake 3: Leaving Collars/Harnesses On 24/7

Constant friction and trapped moisture under straps.

Do instead:

• •Remove gear indoors; wash and dry collars/harnesses weekly in summer

Mistake 4: Not Treating Fleas Aggressively Enough

A single flea bite can trigger intense itching in sensitive dogs.

Do instead:

• •Use vet-recommended flea prevention consistently (and treat the environment if needed)

Mistake 5: Using Harsh DIY Sprays That Irritate Skin

Alcohol, essential oils, and strong fragrances can inflame skin.

Do instead:

• •Stick to canine-safe antiseptics and vet-approved skin products

Expert Summer Add-Ons: Products and Practices That Lower Risk

These aren’t required, but they’re very helpful if your dog is hot spot–prone.

Coat + Skin Support

• •Omega-3 supplements (EPA/DHA): can reduce inflammatory itch over time

Ask your vet for dosing based on your dog’s weight and health conditions.

Quick-Clean Tools for High-Exposure Days

• •Dog-safe cleansing wipes for paws, belly, folds after hikes or swims
• •Antiseptic spray for “hot spot prone” areas (vet-approved formulas)

Environmental Tweaks

• •Provide cool, dry resting spots (cooling mat, fan circulation)
• •Avoid leaving a damp dog in a crate without drying first (humidity pocket)
• •Limit mid-day lake swims if your dog can’t be dried afterward

Sample Summer Plans (Pick One and Follow It)

Plan A: The “Lake Dog” Labrador

• •Daily: 2-minute check behind ears/hips + quick brush
• •After every swim: towel squeeze + HV dry + part-check
• •Weekly: undercoat rake + comb-check
• •Every 4–6 weeks: pro de-shed grooming
• •Bonus: wash collar weekly; remove at home

Plan B: The “Mat-Prone” Goldendoodle

• •Daily: comb-through armpits/behind ears + check for damp clumps
• •Every swim: full dry to skin line (no exceptions)
• •Every 2–3 days: line brush + comb-check
• •Every 4–6 weeks: groomer haircut at a manageable length
• •Bonus: keep ears plucked/managed only if your groomer/vet recommends (not all dogs need it)

Plan C: The “Fold Care” French Bulldog

• •Daily: wipe + dry facial folds and tail pocket (if present)
• •After water play: towel + dry folds thoroughly
• •Weekly: gentle bath or wipe-down if greasy
• •Always: monitor for redness/odor in folds; address early

When Prevention Isn’t Enough: Signs You Need the Vet

Hot spots can go from minor to severe quickly. Contact your vet if:

• •The lesion is oozing, bleeding, or has pus
• •It’s spreading over hours
• •Your dog is in significant pain or can’t settle
• •There’s a strong odor or thick discharge
• •Your dog has recurring hot spots (you may need to treat underlying allergies, ears, fleas, or yeast)

Recurring hot spots usually mean there’s an underlying driver:

• •ear infections
• •allergies (environmental/food)
• •flea allergy dermatitis
• •chronic yeast
• •matting/coat neglect
• •behavioral licking from anxiety or boredom

Solving the root cause is the real “long-term prevention.”

The Takeaway: The Simple System for How to Prevent Hot Spots on Dogs in Summer

If you want a reliable answer to how to prevent hot spots on dogs in summer, focus on what hot spots need to thrive: damp, warm, irritated skin.

Your summer hot spot prevention system:

• •Groom to eliminate mats and excess undercoat (airflow matters)
• •Dry to the skin line after every water exposure (especially behind ears/hips)
• •Detect early with a 2-minute daily check
• •Reduce triggers like fleas, collar friction, and chronic ear issues

If you tell me your dog’s breed, coat type, and summer routine (swimming frequency, grooming schedule, any allergy/ear history), I can help you choose the most realistic plan and tool set for your situation.
