1. Eczema
If a dog lives in a cold and humid environment for a long time, it is easy to induce eczema, which is superficial pyoderma. It starts as a small red rash, which gradually develops into vesicles with pus. In severe cases, it may even ulcerate. Therefore, the owner must keep the dog’s living environment dry and warm. For local treatment, appropriate dosage forms of drugs can be selected according to the stage of the eczema, or medicated shampoo can be used to take a medicated bath. During the treatment, the dog must be prevented from licking and biting the affected area. If yellow pustules appear on a large scale, they need to be taken to a pet hospital for treatment in time to avoid serious infection and aggravation of the condition.
