It looks as if your dog has a skin infection, most commonly caused by an allergy, a skin mite (Demodex) or fleas. 

The allergy could be a due to a protein in your dog’s food or an environmental allergy like to dust, pollens, grasses, etc. 

The allergy causes your dog to itch and chew at the skin which breaks down the skin barrier. This then leads to infection. Skin infections are typically characterized by large areas of hair loss, redness, crusting, flaking, and pustules. A thorough skin examination by your veterinarian should be able to determine the cause of the infection and itch so it can be treated appropriately. Because your puppy is so young I would be very concerned about Demodex as the primary problem. Your dog will most likely need antibiotics to help clear up the infection and possibly an allergy/anti-itch medication like Apoquel, Atopica, or Cytopoint to give some relief while the infection clears up. A medicated shampoo may be beneficial as well (based on the type of infection your veterinarian can recommend the most appropriate one). I would also recommend that he be on a good flea control routinely too. The thyroid gland is located in the throat area but it is probably not what you were feeling. I suspect you may be feeling a large lymph node or just severely inflamed skin tissue judging by the severity of his infection. I hope this helps. Thanks for using Petco Pet Education Center, formerly Petcoach. Best of luck.
