Hi there and thank you for using Pet Coach! It is difficult to say what the growth you are seeing is since there are no pictures. Seeing that Carl is quite a young dog, I would suspect what you are seeing is benign. Many times in dogs this young when we see a mass it is likely a papilloma secondary to exposure to the papilloma virus or a histiocytoma. Both of these typically resolve on their own and will occasionally need surgical intervention for removal. If the mass is not going away on its own or is multiplying in number, I would have this examined by a veterinarian and have further testing performed to help further determine what this could be so that the most appropriate treatment can be recommended. I hope this helps guide you in the right direction! I am also available via consultation if needed.
