The dog's skin is red, what should I do?

There are two reasons why a dog's skin is red. First of all, mechanical damage, too high bath water temperature, too high hair dryer temperature when drying, whipping and so on. Secondly, fungal dermatitis or acaroid dermatosis can cause skin redness at an early stage. At this time, it is recommended to take him to the pet hospital for skin disease screening to find out the cause of the dog's skin redness.
