Dog food is an often-debated topic. There are breeders that have used it for decades with no cases of illness or MBD and have multiple generations of skinks that have been fed dog food without issue. I feed wet dog food but supplement with veggies and insects. I get a batch of organic veggies every few month and process it (clean, cut up, and process in a food processor, dice up greens) I combine all of it and freeze in an ice cube tray and then put in a freezer bag to thaw as needed. My guy won't take veggies unless they are very well processed and mixed with dog food. I usually use yelow and butternut squash, green beans, zucchini, carrot, kale, chard, and a bananna or apple for sweetness. I have ever put raw egg in it as well.. They will eat the shell and egg.
I believe the "raw dog food" the other poster was talking about is the frozen raw meat/ veg dog food mixes you can buy in the pet store. Most places sell them as sausage link looking packages or in patties like frozen sausage. Reptilinks makes a similar product for snakes and I belive omnivores too. These are supposed to have bone, organ meats, and muscle meats, so make a more complete diet.
