If a dog has a skin disease, the first step is to shave off all the dog’s hair to prevent eggs or germs from remaining in the hair. The second step is to use medication. Choose the medication according to the type of skin disease the dog has. If If it is caused by parasites, we need to deworm it. If it is a fungal infection, we need to sterilize it. Finally, we must pay attention to the dog’s nutrition and cleanliness to prevent the dog from getting sick again.
