What to do about dog skin disease and hair loss

Trim the hair around the affected area to prevent repeated infections. Avoid letting the dog scratch itself to prevent wounds. Do not bathe the dog or let it wear clothes.
Since there are many types of skin diseases that cannot be visually identified, it is recommended to go to a pet hospital for a skin scraping examination and fungal lamp irradiation to diagnose the skin disease.(The price is usually between tens to 100)
If you don't want to spend too much money at the pet hospital, you can do the scraping and buy the medication yourself after knowing the cause, which can save a lot of money. Generally, the drugs used for fungal infections include: Pet芬喷雾剂(盐酸特比奈芬喷雾剂), applied 3-4 times a day for topical use. For severe fungal infections, oral treatment with癬净 (please check the ingredients, which are also salt酸特比奈芬) can be considered. The general cure time for skin diseases is relatively long, and treatment should be persevered for about a month.
Pay attention to diet: Avoid feeding the dog beef, mutton, chicken, seafood, and animal internal organs. The diet should be light and focus on dog food with less protein.
If the skin has the following symptoms, apply medications that help regenerate the skin follicles and promote hair growth. You can also combine medication with baths to assist in treatment.

Note also that after contacting the dog, pet owners should wash their hands and disinfect the areas where the sick dog stays, including utensils and toys used by the dog.
