My Dog Had a Hot Spot—And It Came Back With a Devastating Twist
Understanding Hot Spots in Dogs and What to Do If They Return

If your dog suddenly develops a red, inflamed hot spot, you know just how urgent and worrying it can be. Hot spots—also known as acute moist dermatitis—are small, painful skin lesions that appear suddenly, often spreading quickly. While they can heal with prompt care, the real concern arises when these spots come back, sometimes worse than before. In this article, we explore what hot spots are, common causes, why recurrence can be so devastating, and actionable steps to prevent and treat this recurring skin issue in your canine companion.


Understanding the Context

What Is a Hot Spot in Dogs?

A hot spot is a localized area of affected skin characterized by moist, red, inflamed patches, often with oozing or crusting. Dogs commonly get these from self-trauma—licking, scratching, or biting an irritated spot until it evolves into a hot spot. They can appear seemingly overnight and are particularly common in breeds with thick or double coats.

Hot spots are typically painful, causing your dog to become irritable or reluctant to let you touch the area. Even though they heal with care, they frequently return if underlying triggers aren’t addressed—sometimes returning with greater severity.


Key Insights

Why Do Hot Spots Come Back with a Devastating Twist?

While basic hot spots may resolve with topical treatment, recurrence can bring a more serious complication: infection. When a hot spot returns, it may:

  • Become secondarily infected with bacteria or yeast, requiring antibiotics or antifungals.
    - Expand beyond initial boundaries, resulting in larger areas of damaged skin.
    - Never fully heal, leading to chronic irritation or scarring—causing ongoing discomfort and frustration.
    - Trigger behavioral worsening, as pain encourages relentless licking, making management even harder.

This “devastating twist” often signals deeper issues beneath the surface—environmental, allergic, or systemic factors that need thorough investigation.


Final Thoughts

Common Causes Leading to Recurrent Hot Spots

Understanding root causes is critical. Here are frequent triggers that may cause your dog’s hot spot to return:

  • Allergies: flea bites, food allergies, or environmental sensitivities provoke itching.
    - Parasites: ongoing infestation with fleas, mites, or ticks fuels endless itching.
    - Skin infections: unresolved bacterial or fungal infections because treatment was incomplete.
    - Behavioral triggers: anxiety or compulsive licking due to stress or boredom.
    - Moisture and humidity: environments that trap moisture under the coat encourage bacterial growth.
    - Poor grooming or matting: trapping dirt and irritants against the skin.

How to Treat and Prevent Hot Spots Before They Come Back

Effective care requires both immediate treatment and long-term prevention:

Immediate Treatment
- Clean gently with a mild antiseptic or vet-approved cleanser.
- Apply topical treatments—antibiotic ointments or hydrocortisone cream (if approved by your vet).
- Stop licking with an Elizabethan collar or protective bandage.
- Treat underlying causes: flea control, hypoallergenic diet trial, or anti-itch medications.

Long-Term Prevention
- Regular grooming to reduce matting and keep skin healthy.
- Control allergens: consult your vet about allergy testing or antihistamines.
- Manage anxiety with behavioral interventions or calming aids.
- Dry your dog thoroughly after baths or outdoor play—especially in thick-coated breeds.
- Schedule routine vet visits to spot skin issues early.
