Seborrhea in Dogs: Vet’s 2025 Guide 🐶🧴

By Dr Duncan Houston, BVSc – Ask A Vet Blog

🔍 What is Seborrhea?

Seborrhea is a chronic skin condition in dogs characterized by excessive flaking, scaling, or oiliness of the skin. Dogs may appear dusty, greasy, or both—and may smell unpleasant due to bacterial or yeast infections 🦠. Seborrhea can affect any breed, but some are genetically predisposed 🐾.

🧼 Seborrhea Types

Seborrhea is typically categorized into two forms:

1. Seborrhea Sicca (Dry)

Flaky, scaly skin (like dandruff)
Dry coat with white/grey flakes
Common on the back and shoulders

2. Seborrhea Oleosa (Oily)

Greasy skin and fur
Strong odor due to secondary infection
Common in skin folds—neck, belly, ears

In many dogs, both types appear together, creating a mix of oiliness and flaking across different parts of the body 🌡️.

🐶 Breeds at Risk

Primary seborrhea (genetic) is most often seen in:

Cocker Spaniels 🎀
West Highland White Terriers 🐾
Basset Hounds 👃
Shar-Peis and Labrador Retrievers

⚠️ Symptoms

Signs of seborrhea may include:

🧴 Greasy or dry skin patches
❄️ White or yellow flakes
💨 Musty or sour body odor
🔴 Red or thickened skin (if infected)
🐾 Chronic ear infections (otitis)
📍 Lesions in folds, belly, ears, and underarms

🧬 Primary vs. Secondary Seborrhea

Primary Seborrhea

This is inherited and chronic. It cannot be cured but is manageable with ongoing skin care and sometimes medications like retinoids (synthetic vitamin A) 🧪.

Secondary Seborrhea

This form is caused by an underlying condition and is far more common. It typically resolves once the root issue is treated:

Hormonal imbalances (hypothyroidism, Cushing’s disease)
Allergies (environmental or food-related)
Parasites (mites, fleas)
Fungal or bacterial skin infections
Environmental triggers (heat, humidity)

🔬 Diagnosing Seborrhea

Diagnosis involves:

Complete physical exam
Skin scrapings to rule out mites
Cytology to assess bacterial/yeast infection
Bloodwork for hormonal issues
Skin culture or biopsy in unclear cases

🧴 Treatment Options in 2025

Treatment depends on whether seborrhea is primary or secondary. Here’s the approach:

1. Medicated Shampoos

Topical therapy is key for both forms. Common ingredients include:

Benzoyl peroxide: Removes excess oil, follicular flushing
Salicylic acid: Softens and exfoliates scales
Sulfur: Antimicrobial and keratolytic
Chlorhexidine: Fights bacteria and yeast

Tip: Allow 10–15 minutes of contact time during baths. Most dogs need baths 1–3 times a week during flare-ups 🛁.

2. Antifungals or Antibiotics

If infection is present, your vet may prescribe:

Oral antibiotics (for Staph or secondary pyoderma)
Topical or oral antifungals (for yeast—Malassezia)

3. Retinoids (for Primary Seborrhea)

Oral synthetic vitamin A derivatives
Help normalize skin cell turnover
Require close veterinary monitoring due to side effects

4. Supplements

🫒 Omega-3 and Omega-6 fatty acids support skin health
🐟 Fish oil capsules or vet-formulated skin support chews

📋 Home Care Tips

Use soft, clean bedding—wash weekly
Groom and brush regularly to remove loose flakes
Monitor ears for signs of otitis (redness, odor, shaking)
Keep skin folds clean and dry (especially in Basset Hounds, Bulldogs)

📆 Long-Term Outlook

Seborrhea is manageable. Dogs with primary seborrhea may require lifelong care, while secondary seborrhea often resolves with successful treatment of the underlying cause. With consistent therapy, most dogs live happy, itch-free lives 🐾💖.
