Symptoms of dog dermatitis:

1. The dog’s skin appears red and swollen in flakes, strips or irregular shapes, and may be covered with swollen skin when there is exudation. When the skin is damaged, erosion or ulcers may appear, and there may be local pain and itching.

2. When the skin is covered with a large amount of inflammatory exudates and suffers from chronic dermatitis, the skin coat may be shed. The skin peptide is thickened and cracked.

3. When suffering from fungal dermatitis, the affected area will be hairless, with white powdery scabs locally, and red protrusions under and around the scabs.

4. When suffering from parasitic dermatitis, red rash-like nodules can be seen on the head, back, and abdomen, with yellow scabs on the surface, hair loss, and severe itching.
