Itchy, dry flaky skin.  Yellow crusts on skin.  Red, sore skin.  Fur loss around the nose and eyes.

Possible Causes

Many causes.  Fungal infections (ringworm) being the primary cause.  Allergies or hormonal conditions can also be implicated.  Poor nutrition may also affect the skin and fur. Excessive sandbaths (combined with central heating) may excessively dry the skin causing it to flake.
