For dog fungal infections, it is best to take oral fungal treatment drugs and take a medicated bath, so that the dog can recover faster. You need to soak for ten minutes during the medicated bath, which will have a better effect. Fungus is generally caused by the dog's hair not being dried after bathing, bathing too frequently, using human shower gel, or malnutrition. If you need to improve the dog's diet and enhance nutritional supplements, choose a dog-specific shower gel every two weeks. Just take a bath once.
