Causes of seborrheic dermatitis in dogs

Causes of seborrheic dermatitis in dogs:
1. Genetic factors. Primary seborrheic dermatitis has no underlying cause and often runs in families.
2. Own endocrine disorders.
3. Unbalanced diet and lack of nutrition.
4. Parasitic infection.
5. For most dogs with excessive sebum, the most common underlying causes are hormonal disorders and allergies. When the dog is younger than five years old, allergies are more likely to be the underlying cause. If dander begins to appear on a middle-aged or older dog, a hormonal disorder is more likely to be present. If your dog is not showing signs of harassment, this may rule out allergies, scabies, and other itchy conditions.
6. Infected by other dogs.
