Causes of fungal skin diseases in dogs:

1. Infection caused by some bacteria on the dog’s skin, which causes fungal skin diseases.

2. If the owner fails to dry the dog’s hair after bathing it, the dog may become infected when it comes into contact with sick dogs or contaminated items.

3. Dogs have lived in a humid environment for a long time, or the living environment is unhygienic.

4. Dogs lack vitamins. A dog's nutritional imbalance will reduce its resistance, making its skin susceptible to pathogens and causing skin diseases.

5. Frequently cleaning the dog's coat too much, or often using alkaline shower gel to bathe the dog, destroys the protective layer of oil on the dog's skin.
