7 Surprising Things That Make Your Dog’s Hot Spots Worse

Hot spots — or acute moist dermatitis — emerge when a small skin irritation spirals into a painful, oozing sore. While most dog owners know that fleas, allergies, and moisture trigger them, several surprising and overlooked factors in daily life can worsen or prolong your dog’s suffering. Worse, you may unintentionally be feeding the cycle! This guide helps you unveil the hidden triggers in your dog’s environment, daily routine, or even your caregiving habits. By identifying and correcting these issues, you’ll drastically reduce recurrences and speed up healing.

7 Surprising Things That Make Your Dog’s Hot Spots Worse (And How to Stop Them)

Some surprising things that can make hot spots worse have been overlooked for a long time. We're here to figure them out!

1. Over-Grooming or Incorrect Grooming Techniques

Why Grooming Can Backfire
While grooming is essential, overgrooming, using the wrong tools or technique, can cause micro-injuries—tiny nicks, irritations, or matted areas—that trap moisture.

Common Mistakes:

• Over-grooming/Using metal combs on thin or irritated skin

• Skipping deshedding tools during shedding season, causing tangles

• Bathing with harsh, human shampoos

How to Fix It:

• Choose gentle grooming brushes suited to coat type

• Introduce professional-grade deshedding once a week

• Use mild, dog-specific, pH-balanced shampoos. Healthy dogs typically need a bath every 4–6 weeks, while dogs with skin issues may require medicated baths 1–2 times weekly as prescribed by a veterinarian.

Real-Life Example
Lucy, a German Shepherd, developed hot spots after regular brushing with a slicker brush over ultra-sensitive skin. Her owner switched to a comb with plastic tips and now brushes gently—her outbreaks resolved.

2. Inappropriate Diet or Food Sensitivities 

Hidden Food Triggers
Even grain-inclusive diets can drive skin irritation—not just obvious allergens like beef or dairy.

• Common culprits: beef, chicken, corn, soy, artificial dyes

• Chronic inflammation: processed food additives exacerbate itchiness and immune sensitivity

What You Can Do:

• Start an elimination diet for 8–12 weeks

• Transition to high-quality, limited-ingredient food

• Add anti-inflammatory supplements: omega-3 fatty acids, turmeric, probiotics

Veterinary Insight
Dr. Malik reports that many dogs with recurring hot spots improved dramatically on fish-oil-enriched diets, even with mild food sensitivities.

3. Environmental Household Irritants

Unexpected Triggers
Chemicals, cleaning agents, and air fresheners can trigger skin reactions or worsen existing hot spots:

• Fabric softeners left in bedding

• Formaldehyde in certain carpets/textiles

• Tea-tree oil or essential oils on pet bedding

   

Subtle Signs:
Dry, flaking skin or persistent scratching not limited to lesions

Solutions:

• Wash pet bedding in fragrance-free, hypoallergenic detergents

• Use pet-safe cleaning agents only. Do not frequently change the household cleaners or others. This reduces the risk of irritants.

• Keep canine-accessible home areas well-ventilated

Case in Point
Milo’s owner switched to plant-based cleaners and noticed his hot spots dwindling within days. He even eliminated scented candles and indoor sprays.

4. Cat or Other Animal Interactions 

Why Cross-Species Play Can Be Problematic
Even well-groomed cats can irritate a dog’s skin:

• Cat saliva contains enzymes that can mildly degrade canine fur. While it's true that cat saliva contains enzymes, the statement about it mildly degrading canine fur is not a widely accepted fact. 

• Play behaviors like mutual licking can introduce fungal spores

How to Safeguard Your Dog:

• Limit unsupervised interactions during outbreaks

• Wipe down the dog’s coat after playtime

• Use veterinary-approved antimicrobial sprays post-grooming

Tip
Designate separate rest beds and wipe shared toys between pets.

5. Stress and Emotional Upset

The Emotional–Physical Connection

Dogs are sensitive creatures, and stress can lead to increased itching and licking, which damages the skin barrier and makes it more prone to hot spots.

• Separation anxiety, changes in routine, and boarding stress

• Intense weather events (fireworks, thunderstorms)

Signs of Stress-Triggered Hot Spots:
Chewing/clawing behavior worsens during storms or travel

Stress-reducing Strategies:

• Use pheromone diffusers (e.g., Adaptil)

• Provide scheduled walks and play

• Implement a calming supplement or anxiety wrap

• If needed, desensitization training

Example
During thunderstorms, Zoe experienced flare-ups. After adding a simple anxiety wrap and background white-noise, the hotspot frequency dropped by 60%.

6. Using Wrong Topical Products When Treating Skin Issues

Not All Sprays Are Safe
Human or inexpensive canine sprays may contain:

• Alcohol, which stings and dries the skin

• Steroid-based sprays that mask symptoms but worsen infections

Product Pitfalls
Ingested steroids can suppress the immune system, delaying healing long-term. Overuse of antiseptics like chlorhexidine can irritate healthy skin.

Safer Options:

• Puainta® Quantum Silver Antifungal Skin Spray—safe for licking, tackles bacteria/fungus, enriched with botanicals. It targets the hot spots and provides itchy relief quickly.
  
  

• Vetericyn Plus

• Vet’s Best Hot Spot Spray

How to Use Topical Sprays Correctly:

• Clean and clip hair before applying

• Spray 3–5 times daily until scabs forms

Success Story
Max recovered from a severe thigh hot spot within a week using quantum silver spray and no antibiotics. The lesion cleared faster than previous recurrences.

7. Neglecting Secondary Health Issues 

Hidden Stressors
Underlying conditions can fuel frequent flare-ups:

• Hormonal imbalances (thyroid, Cushing’s)

• Chronic ear infections or dental disease. The discomfort led to restlessness and excessive scratching.
  
  Puainta® Quantum Ear Drop Relieves itching, Cleans Earwax, and relieves irritation and inflammation. It targets 90% of ear problems, including ear mites, yeast infections, earwax buildup, and itching and it effectively breaks down stubborn wax, eliminates odors, and prevents microbial growth.
  
  

• Parasite carriers like mites or demodex

Signs to Watch:
Excessive yawning, hair thinning, lethargy, recurring ear odor

What to Do:

• Schedule a detailed veterinary check-up (CBC, thyroid panel)

• Treat ear and dental issues promptly

• Implement holistic parasite prevention

Case Study
Rally, an overweight Labrador, had hot spots alongside repeated ear infections. After weight management and teeth cleaning, his hot spots reduced by 80%.

How to Break the Fluency: A 5-Step Healing & Prevention Plan

1. Vet Confirmation
   Clip, swab, and culture lesions. Confirm any secondary infections or endocrine issues.

2. Targeted Grooming
   Use gentle tools. Focus on problem areas and maintain mat-free fur.

FAQ 

Q1: Can grooming brushes cause hot spots?
Yes. Over-brushing thick or sensitive skin with stiff brushes can cause micro-abrasions, inviting bacterial growth.

Q2: How do I know if my dog has a food allergy causing hot spots?
Look for flare-ups linked to diet changes or elimination test results. Reductions during elimination support this.

Q3: Are fragrance-free household products better?
Absolutely. They eliminate volatile chemicals dogs inhale or sit on. Even laundry fragrances can linger on bedding and fur.

Q4: Can stress truly worsen hot spots?
Yes. Stress triggers cortisol spikes, which increase scratching and reduce skin healing. Manage anxiety with environmental enrichment.

Q5: Is Puainta® spray safe for long-term use?
Yes. It’s alcohol-, paraben-, and steroid-free, with natural botanicals and a nano silver layer. Use until healing is complete.

Q6: When should I schedule a vet check?
If a hot spot is larger than 2", oozing pus, foul-smelling, or paired with lethargy, vet consultation and possibly antibiotics are needed.

Q7: Can other pets trigger my dog’s hot spots?
Yes—fungi, saliva, or debris from other animals can irritate sensitive areas. Wipe down the coat after play.

Q8: What’s the healing timeframe?
With integrated care, mild hotspots can clear in 3–5 days. Severe cases may require 7–14 days plus potential vet-prescribed treatments.

Q9: Can hot spots lead to larger health problems?
Yes. If untreated, they may evolve into severe bacterial or fungal infections and cause systemic issues, especially in immune-compromised dogs.
