Oh i'm so happy you brought Riley home! I can't wait to see pictures of the two of them.
i think the best thing to do for his breath is a dental. then you can start from scratch. However since he has a heart murmur you need to make sure your vet is experienced enough to anesthetize a small dog with a murmur. if your sure about him doing it then i'd look for a board certified dentist. also as i'm sure you know, have a full blood panel done before hand as well.
