My male 3year old dog has been excessively licking his penis and now there are sores that are starting to look infected. He isn’t neutered and still very active. Any advice or home remedies that you can suggest would be appreciated

This looks like scrotal dermatitis, which is not uncommon in unneutered dogs. Often, there is an infection present, which will need prescription medication to treat it. This particular problem tends to take a long time to heal and can get worse without proper treatment. For these reasons I recommend taking Dexter to the vet for an accurate diagnosis and treatment. For now, wash/spray the area with cool, clean water (no soap or other antiseptics) for at least 5 minutes at a time. Do this at least twice a day. It's important not to put any ointments or creams on this, because they will likely be licked off and may not be helpful anyways. I hope that helps and Dexter gets better soon.
