here's from Sabine (nutritionist) on this topic ..."If we are talking species appropriate, no, they certainly aren't. You wouldn't find a wild canid ingesting any significant amounts of legumes or potatoes. Other than if they were really starved and desperate maybe, but even then, in an unprocessed state these are pretty much indigestible since the dog's GI system isn't really equipped to break them down.
However, that doesn't mean that in the diet of domestic dogs they are "just fillers", since when cooked, the dogs CAN digest them and DO utilize the nutrients in them. That's a proven fact. If it weren't, I would have an awful lot of special-needs client dogs who would not survive because they can't tolerate a standard (and/or species appropriate) diet.
That doesn't mean that vegetable-based ingredients should make up the major part of the diet of a dog, and that's where we come to "grain free" diets that appear high in protein because of the addition of a large amount of vegetable protein. Example: pea protein powder, as added to kibble dough, can be 85% protein. Even if it makes up only 20% of a formula, that boosts the overall protein content considerably, even without the addition of much quality meat."
