Dog Hot Spot Healing Stages Explained

As pet parents, we’ve all seen it happen. One moment, your four-legged friend is perfectly fine. The next, they’re obsessively licking and chewing at a red, raw patch like it’s the only thing that matters. That irritated area, also known as acute moist dermatitis, can pop up fast, spread even faster, and look downright alarming if not handled properly.

But the good news? These irritated patches can clear up fully with proper attention. In this detailed guide, we’ll take you through each phase of the process—what you’ll notice along the way, how long it could last, and how you can make things easier for your four-legged companion.

What Is a Dog Hot Spot?

An irritated, infected patch on their skin can show up out of nowhere and get worse fast. It often starts because they’ve been licking, chewing, or scratching one area too much. That constant attention usually comes from something deeper bothering them underneath, like:

• Flea bites or insect stings

• Allergies (food, seasonal, environmental)

• Moisture trapped under the fur (like after swimming)

• Ear infections

• Dirty or matted coats

• Cuts, scrapes, or irritations that get licked

Once they start obsessing over an itch or irritation, it quickly snowballs into an open sore—and just like that, it turns into a red, oozing mess that seems to get worse every time you look.

How to Recognize a Hot Spot

Early recognition is key. Here are the signs:

• Red, inflamed skin

• Wet or oozing wound

• Hair loss around the area

• Intense licking, biting, or scratching

• Bad odor from the infected spot

• Scab formation in later stages

• Pain when touched

These itchy flare-ups often show up around the head, neck, hips, or legs. Breeds with long or dense coats—like Golden Retrievers, Labs, and German Shepherds—tend to deal with them more frequently.

The 6 Dog Hot Spot Healing Stages

Now, let’s walk through each stage they’ll experience—from that raw, irritated patch at the start to when their coat grows back and things finally calm down.

Stage 1: Irritation and Overgrooming (Days 1–2)

What’s Happening:

The skin gets irritated—often triggered by a bite, scratch, or some kind of reaction. They start licking, scratching, or chewing at the area, which quickly makes it worse.

Signs You’ll See:

• Redness

• Hair loss

• Moist skin

• They just keep scratching and licking that same irritated area—can’t seem to leave it alone.

What You Should Do:

• Interrupt the licking immediately. Use an e-collar (cone), bandage, or soft inflatable collar.

• Examine for fleas, wounds, or possible allergies.

• Clean the area with chlorhexidine, saline, or an antiseptic pet wipe.

• Call your vet if it’s worsening or if you’re unsure. Early treatment stops it from progressing.

Stage 2: Open Sore and Bacterial Infection (Days 2–4)

What’s Happening:

The licking/chewing has broken the skin, and bacteria have entered. Now it’s infected. This is the peak of the “hot” stage—it’s painful, smelly, and alarming.

Signs You’ll See:

• Weeping wound or pus

• Bad smell

• Swelling

• High sensitivity to touch

• Worsening hair loss

What You Should Do:

• See your vet. Most need oral antibiotics, topical treatments, or anti-inflammatories at this stage.

• The vet may shave the area for airflow and easier treatment.

• You’ll need to clean the spot 2–3 times daily, dry it, and apply medication like a veterinary ointment or cream.

• Continue using the cone or e-collar to stop the licking.

Key Reminder: Avoid applying human ointments like Neosporin unless your veterinarian gives the green light. Some ingredients may be harmful to them.

Stage 3: Scab Formation and Drying Out (Days 5–7)

What’s Happening:

The infection starts to subside. The wound begins drying, forming a crust or scab. Hair loss may still be visible, but inflammation reduces.

Signs You’ll See:

• Reduced redness and swelling

• Crusting or scabbing over the wound

• Less oozing

• Dog seems less bothered

What You Should Do:

• Keep cleaning gently to avoid dislodging the scab.

• Maintain medications until finished (don’t stop antibiotics early).

• Keep the area dry—avoid swimming or bathing them unless advised.

• Continue monitoring for signs of itching or relapse.

Pro Tip: Fresh air makes a big difference. When possible, let them relax in a dry, well-ventilated space inside.

Stage 4: Skin Repair Beneath the Crust (Days 7–14)

What’s Happening:

Beneath the surface, new skin cells are forming as the body works to restore the deeper layers. This is when the restoration process truly gains momentum.

Signs You’ll See:

• Smaller scab

• No more wetness

• Less sensitivity

• New skin tissue starting to show

What You Should Do:

• Avoid picking at or cleaning away the scab—it’ll fall off naturally.

• Reapply healing ointments if prescribed.

• Let the area breathe, but keep the cone on if they start licking again.

• Watch for signs of re-infection (like renewed redness or pus).

Stage 5: Scab Falls Off, Pink Skin Appears (Days 14–21)

What’s Happening:

The scab has done its job and now starts to flake off naturally. Underneath, you’ll see new, pink skin. It might look a little weird or shiny—but that’s a good sign.

Signs You’ll See:

• Scab shrinks or flakes away

• Pink, delicate new skin underneath

• Slight itching (healing itch)

• Hair starts to grow back

What You Should Do:

• Prevent scratching as the scab falls off—itching may return briefly.

• You can now discontinue some treatments if the vet gives the okay.

• Keep them well-groomed to avoid mats or irritants building up around the affected area.

Note: Some animals develop darkened or scarred skin in the affected area. This typically lightens as time goes on.

Stage 6: Full Recovery and Hair Regrowth (3–6 Weeks After Start)

What’s Happening:

The skin has strengthened and turned pink, the coat is filling in again, and your furry friend looks and feels just like their usual self. That sore? It’s gone without a trace.

Signs You’ll See:

• Full closure of wound

• Pink skin fading to match normal tone

• Fur regrowth

• No more itching, licking, or scratching

What You Should Do:

• No more treatment needed—just regular grooming and prevention.

• Identify the original trigger (allergy, flea, etc.) and take steps to prevent future flare-ups.

• Give yourself some credit for handling this like a caring and dedicated animal guardian!

Frequently Asked Questions from Caring Owners

Is it okay to pop or drain the irritated skin area?

Definitely avoid trying to pop or drain the sore yourself. When the skin is broken, it’s already vulnerable to infection. Attempting to open or squeeze the affected area at home can introduce more bacteria, pushing the infection deeper or causing it to spread to surrounding skin. This can lead to increased pain, swelling, and complications that may require more intensive treatment. A trained professional has the proper tools and sterile environment to safely address such wounds if necessary. So, it’s always best to leave this kind of care to the veterinarian to ensure your furry friend’s comfort and prevent worsening of the condition.

Can I use coconut oil or natural remedies?

In some cases, applying coconut oil may help calm and moisturize irritated skin, especially when the irritation is mild and the surface is intact. Coconut oil contains natural antibacterial and anti-inflammatory properties that can provide soothing relief. However, it’s very important to consult with your veterinarian before using it, particularly if the affected area is raw, broken, or showing signs of infection. Using coconut oil on an open wound without professional guidance might trap bacteria or worsen the condition. Your vet can advise whether this natural remedy is safe and appropriate for your furry friend’s specific situation.

How can I stop these skin irritations from returning?

• Control fleas

• Manage allergies

• Maintain your furry friend’s coat clean and dry.

• Brush out matted fur

• Address boredom or anxiety that leads to licking

When to Call the Vet

Call your vet if:

• The hot spot spreads or worsens

• There’s blood or pus

• Your furry friend is experiencing significant discomfort.

• Fever or lethargy develops

• It doesn’t improve after 2–3 days of care

Final Thoughts: Patience, Love, and a Little TLC

Seeing your furry friend struggle with a painful skin irritation is tough. They feel uncomfortable, and it’s challenging to keep them from scratching that persistent itch.

With prompt attention, careful monitoring, and some patience, most cases clear up fully within one to three weeks. The important part is stopping the constant licking and scratching, addressing the infection, and allowing the skin time to repair itself naturally.

And hey—those belly rubs, treats, and cozy cuddles during this time? They make everything a lot easier for both of you.
