Not all - some of us really need protein, and there's precious little animal protein on the left (plant proteins are far less bioavailable than animal proteins).
In reality, your dogs will be healthier and likely live longer (and better) if you don't give them 'people food'. Easier to maintain their weight. Too many people feed their dogs human food, it's no different than feeding your kid junk to 'make them happy' - all you end up with is a weight problem (fat dogs and fat kids).
