Overview
Seborrhea is a skin condition causing excessive flaking (dry seborrhea) or greasiness (oily seborrhea) — or a combination of both. Primary seborrhea is genetic and lifelong. Secondary seborrhea is far more common, triggered by allergies, hormonal disorders, fungal infections, or nutritional deficiencies. It gives the coat a dull, flaky, or greasy appearance with a characteristic musty odor.
Symptoms to Watch For
- Excessive dandruff or greasy, waxy skin
- Musty or rancid odor from the coat
- Itching and redness
- Thickened, scaly patches especially on elbows and ears
- Recurrent ear infections
How Nutrition Helps
Omega-3 and omega-6 fatty acids are the most effective nutritional intervention — they normalize skin oil production and reduce flaking. Zinc supports skin cell turnover, and vitamin A regulates skin cell growth. For secondary seborrhea, addressing the underlying cause (allergies, thyroid disease) through diet is key.
Prevention Tips
- Feed omega-rich diet or supplement with fish oil
- Regular bathing with medicated shampoo as directed by vet
- Address underlying allergies or hormonal issues
- Don't over-bathe — it strips natural oils
- Keep skin moisturized in dry climates
Breeds at Higher Risk
Cocker Spaniels (most common), Basset Hounds, West Highland White Terriers, German Shepherds, and Labrador Retrievers (primary seborrhea).
