It's asking if I'm new to raw. I'm not sure what to answer.

We're interested in your experience with raw pet food, so we can offer you the vest support if needed.

So, if you've never fed your pet raw food before (any brand, not just Bella+Duke or homemade raw food), select 'New to raw.' If you have fed raw food before (even if it's only a couple of times), select 'Experienced'.
