Hi and welcome!
Our pets stomachs can handle a lot more than us. As you may have noticed, they groom and lick other dogs and even eat poop with no problems at all. There's a variety of raw food that you can feed, some come ground and prepackaged. For my clan, they eat meat from grocery stores, such as chicken quarters, whole ducks, beef parts, etc.
Here's a thread on how to start and if you have any more questions, don't be afraid to ask!
