There are several common skin diseases in Polish Lowland Sheepdogs:

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 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.

Methods to prevent skin diseases in Polish Lowland Dogs:

1. For dogs that already have skin diseases, it is best to consider their physical condition and the severity of the disease. Only when the body's immunity is improved can the dog's disease heal faster, and it can also prevent Papillon dogs who do not suffer from skin diseases from being troubled by diseases.

2. Spring is the season when dogs change their hair. Frequent combing can prevent the shed hair from remaining on the body. The hair after each combing is more ventilated and dry, reducing bacterial growth.

3. Fungal skin diseases are also the most common skin diseases in dogs. In the daily environment, kennels, food bowls and other things used by dogs must be disinfected and sterilized in time.
