Hello. Your puppy may have mange, but this sounds a bit more like something we call puppy pyoderma, a staph infection in the skin. Seen often in puppies, it is from a puppy having a weak & immature immune system. I would see your veterinarian about this because it requires skin scrapes to rule out mange, & cytology to confirm the presence of the skin bacteria that causes the lesions. Whatever the cause, your veterinarian will recommend a treatment until King gets a little older & is able to fight these situations off by himself.
