The reasons why dogs will get skin diseases in summer:

1. In summer, owners shave their dogs, which directly exposes the skin to ultraviolet rays. Ultraviolet rays may cause dogs to suffer from skin diseases. Skin burns and even heat stroke make dogs more susceptible to skin diseases.

2. The high temperature and high humidity environment in summer is very suitable for fungal reproduction. If the dog's hair is shaved, the skin will be in direct contact with germs in the environment and cause skin diseases.

3. In summer, owners bathe their dogs too frequently, and the dog’s skin is very thin, so it is difficult to avoid causing damage to the skin.

4. The weather is hot in summer, and the dog’s resistance decreases, making the skin susceptible to infection.

5. Dogs have heat stress reactions in hot environments, which allows some harmful bacteria or parasites to take the opportunity to invade the body and cause skin diseases.
