why would you hope they are feeding raw? do you think raw is the answer to all dog food related, health related issues?
feed what works, and sometimes not even every dog in the same household can eat the same thing.
If the question is what is the most popular dry dog food VERSUS what is the most popular dry food that Labrador breeders feed you will get distinctly different opinions !! We have to remember that a significant portion of pet owners pick up a bag of kibble-N-bits when they get their gas at the corner store. Doesn't make it right or good, simply makes it convenient.
