Most dog skin disorders are immune system related. Some of these disorders include demodectic mange, eczema, scalp psoriasis, ringworm, seborrheic dermatitis and yeast infection. Another form of rash is dog scabies. This is not immune system related. Dog skin disorders are indicated by itchy scalp, skin rashes, hair loss, scabs or very dry skin.
