Most skin disorders and rashes emerge in response to a problem with the immune system.

Demodectic Mange
-
A Demodex mite causes Demodectic mange of which there are several types. Demodex canis is the most common type of microscopic mite that causes this ailment. Some dogs may never experience symptoms despite carrying these mites, while others experience a suppressed immune system indicated by physical symptoms. Should the mites get the upper hand, the result is typically a serious skin disorder requiring veterinary intervention.
Eczema
-
In dogs, eczema refers to hot spots or moist dermatitis seen as a raw or unsightly skin disorder. There are several causes for this condition, the most common being a bacterial infection. Bacterial contamination can occur anytime the skin is broken and the presence of moisture on the skin. Typical symptoms are itching and irritation of the skin, causing an itch-scratch-chew cycle that must be broken for proper treatment of the infection.
Scalp Psoriasis
-
Scalp psoriasis appears from a weakened immune system where T-cells divide too rapidly, allowing accumulation rather than shedding. There are several types of canine psoriasis, though scalp psoriasis is the most common and typically presents as bright and scaly plaques on the elbows, scalp, legs and sacral area. A key cause for this condition is an allergic reaction to commercial dog foods. The treatment for this ailment is similar to eczema and seborrheic dermatitis, according to Caroline Tanaka, a veterinarian in Austin, Texas.
Ringworm
-
Ringworm is a type of fungus that is quite contagious between dogs, other animals and even humans. It affects the body, scalp and feet seen as scaly patches and hair loss. Skin infected by ringworm will break off easily, and the resulting rash can extend across the entire body. Ringworm infections can also create yellow crusts on the skin. The treatment process for ringworm can last between three to eight weeks and treatment must continue until the dog tests negative for possible reinfection.
Seborrheic Dermatitis
-
Seborrheic dermatitis is a disorder that affects the oil glands behind the ears, on the face and on the scalp. It usually causes inflammation of the scalp, waxy scaling and skin rashes that become red and irritated. This ailment results from yeast known as Pityrosporum ovale, which is also responsible for dandruff. The condition gradually worsens, typically appearing as dandruff before becoming more serious. An anti-yeast diet is vital in treating this ailment, coupled with medication from your veterinarian.
