A couple of things come to mind as possibilities. This could be an acute hypersensitivity reaction to something - bug bite/sting, perhaps - or possibility a severe bacterial infection called furunculosis. There are also some immune-mediated/auto-immune diseases that attack the top of the nose. See your vet about this. An appropriate treatment plan might be to start antibiotics and if no improvement after 2 weeks consider a biopsy to obtain a definitive diagnosis.

    Calluses can sometimes cause skin growths of a similar color to the nose if they are near them, however if more are appearing rapidly, or if they are bothersome to your dog it is best to have them looked at to rule out other causes such as skin tumors, allergic reactions, or other skin-based growths. Having your vet take a look and biopsy them may be best to determine what they are and how best to treat them. If they are very bothersome to your dog, having him wear an Elizabethan (cone) collar to prevent scratching and trauma to the area is best until your vet can examine him.
