C I don't think she recommended fruits or veggies, either. I don't think it hurts to add plant matter to dogs' diet. I don't know if they need it, but then, I'm no expert. I think where it might benefit them is the added fiber, like eating the fur/skin of prey would add fiber. But again, I'm by no means an expert. Also just thinking out loud.
The reason I think dogs need fruits and veggies is because, though many won't admit it, wolves scavenged and ate what they could in bad hunting times. PLUS, our dogs really aren't wolves, and the majority of the breeds of today were developed eating what we ate and what they could catch when people didn't have enough for them. They were fed breads, fruits, vegetables and meat scraps. I've even read (somewhere) that the fruits and vegetables that a dog gets should be based on the F&V's available in their country of origin. Like Barkly should get plenty of barley (nope), cabbage, fish carrots, and potatoes since he's a breed that's over 1000 yrs old and that's what they had the most readily available in Wales. Well Barkly hates fish so that's out too.
Interestingly enough, a lot of the Russians believe that this is how Vlad's breed should be fed too despite the breed being less than 100 yrs old, but his food is now limited to potassium amounts, and though their ancestors had grains, V&B get limited to a lot of organic chick peas and SOME quinoa and chia seeds to replace the sweet potatoes I used to give them. I specially mark the packages of V&F for Barkly where I put sweet potatoes in the mix so that Vlad doesn't get it.
The Russian women I've talked to said that processed dog food wasn't available in their country until the past couple of decades, and this breed definitely wasn't used to getting it. They claim it used to be nothing for these dogs to live 15 and still be working at age 13 eating the food of their people, and they blame the shortened lives on the foods they're fed now.
So, yes. Mine are going to get F&V's because I've been told more than once to since these breeds were developed on these foods. Plus, I'm no longer so sure that they get all the vitamins and minerals they need from the meat available today since the meat we eat is fed differently from the past generations too.
