It is also possible that the dog is not bathed and dried, causing the skin to become moist, and ultimately leads to the occurrence of eczema skin disease.

There are several common skin diseases in dogs:

1. Eczema

Eczema develops very quickly and spreads very quickly. Eczema is mostly caused by dogs scratching the same area over and over again. Especially when the weather is hot and muggy, it is easy to develop eczema when the dog scratches the skin. Owners should try to avoid infection of their dog's skin and keep it dry.

2. Scabies

It is a contagious skin disease caused by scabies mites and is accompanied by severe itching and eczema-like changes. The main clinical features are severe itching, hair loss and eczematous dermatitis.

3. Mites

Mites are also a common skin disease in bulldogs. In fact, most dogs are born with mites, and cross-breed dogs are no exception. The problem arises when the dog's immunity to the mites decreases and the mites are unable to be suppressed.
