In a young dog these are often a little cyst or a mass known as a histiocytoma. These may grow a little bigger, but eventually go away on their own after a couple of months. I think it would fine to just monitor this for now. If grows rapidly, or breaks open, or has any other dramatic changes, then it's best to have your vet examine Capone in order to definitively diagnose the cause of this and provide the necessary treatment. Below is a link to more information about the suspected mass. https://vcahospitals.com/know-your-pet/skin-cutaneous-histiocytoma I hope that helps and all is well with Capone.
