- The affected area of the skin is swollen.
– Nodules stage
- The erythema stage quickly turns into the nodule stage.
- But the nodule is about the size of a green pea, pink-red colour.
– Blister stage>
- The nodules quickly turn into blisters filled with light-coloured fluid.>
- Some blisters rupture due to increased endodermal pressure to secrete fluid.>
– Scaly stage>
- The exudate gets absorbed and the blisters dry out.>
- Then the tension of the epidermal horny layer gradually decreases, blisters flatten, the skin is sloughed.>
- The epithelium splits and forms a scab on the surface of the skin. The skin gradually recovers back to its original state.>
– The impetigo phase>
- In cases, the pathological process increases, the stage of impetigo will develop.>

- The pustules rupture on their own or when the dog scratches, the pimples break open and pus comes out.>
- The bacteria develop in the place where pustules rupture.>
– Pus flakes stage>
- Under the influence of many proteolytic enzymes, pustules are broken, the skin is congested, swelling in the affected area.>
- If the area with Eczema exposes to the air and is not exposed to water, the surface will quickly dry out, forming a scaly yellow-green colour.>

– Local changes in the infected skin cause itching.>
– Under unfavourable conditions, the acute progression of eczema can turn into subacute or chronic.>
