I feed Bella Blue Buffalo Lamb and Brown Rice. It's rated at a 4 on the site that Enneirda recommended. She doesn't have any problems eating though. The dog will eat anything!!!
As a side note about food - we first had Bella on a chicken variety but her eyes were especially goopy and she was itching a lot. Our trainer suggested that it might be a food allergy. We switched to lamb and haven't looked back. Her eyes are still a little goopy, but not nearly as bad and she doesn't itch anymore!
Good luck with finding the right food for you guys!
