I recommend getting him in to see your vet as soon as possible about the loss of appetite and diarrhea. Puppies that young can dehydrate easily and their blood sugar can drop quickly to life-threatening levels. The diarrhea could be caused by parasites, a bacterial or viral infection, or possibly swallowing something he shouldn't have, irritating the GI tract or, more seriously, getting stuck and causing an obstruction. The skin I'm less worried about, though that can be addressed at the same visit. Many puppies develop what is called puppy pyoderma, which is roughly equivalent to acne in humans. Most outgrow it and it rarely gets bad enough to require medication, but sometimes antibiotics and therapeutic bathing is needed to help them heal more quickly.
