My vet is giving me a hard time for feeding my dogs a raw diet and says orijen is a crappy kibble.?

She went as far to say I'm irresponsible for putting my dogs at risk for bacterial infections from feeding raw. She said orijens has not been scientifically studied & tested to be safe for dogs. Also, said too much protein is harmful to dogs. She ended her rant with, just because a specific food is expensive, doesn't make it good. She left the room and came back with a bag of science diet and said this is the best food out since Hill's been around the longest and does scientific studies on their food. I'm still feeding my dogs the freeze dried raw food made by Stella & Chewy and orijens puppy kibble chicken flavor. They love it. Ky question is, do vets really know what's best and should I take her advice?
