The causes of dog eczema:

1. It is caused by stimulation from various factors, under the action of external physical factors and chemical factors, such as mechanical compression, Friction, bites, scratches, mosquito bites; certain internal medicines, topical medicines, disinfectants; unclean skin, irritation from dirt, etc.

2. Poor feeding and management conditions, such as moisture in the kennel, can stimulate the body, cause skin allergies, and cause eczema. Excessive carbohydrate intake is more likely to cause eczema. The disease is more common in seasons with higher temperatures and higher humidity. In my country, summer and autumn are the most common seasons, especially May to September.

3. Nutritional deficiency. If the dog lacks vitamins and trace elements, the dog's skin will have low resistance and may also cause eczema.

Symptoms of dog eczema:

1. Acute eczema: At the beginning of the disease, the affected area appears as punctate or erythematous eczema of different shapes, and the affected dog may feel itching. As the disease progresses, papules, vesicles, pustules, and erosion stages may appear. For example, in the pustular and erosive stages, most people have microbial infection, the skin has an abnormal odor, and there is skin itching. Sometimes dogs cause skin damage due to scratching and friction, which aggravates dermatitis. Typical acute eczema presents as small moist papules with scattered small blisters on the papules, and some may be dissipated.

2. Chronic eczema: mostly caused by the transformation of acute eczema. Repeated stimulation and repeated attacks are characterized by thickening of the skin, desquamation, pigmentation, rough coat, inverse erection, and increased itching. More common on the back or limbs.
