Another great option is fresh green tripe. You may have to order it online, but some dog feed suppliers that sell raw have it in their freezers. It ignites the 'instinct' and stimulates appetite.
Also bear in mind a dog wont starve himself. Don't let your family guilt you! Dogs can go up to a week without eating according to my vet (even though thats not ideal!) just be patient! let him get hungry. Train him - don't let him train you!
