"What human food is good for dogs?" and "What human foods does your dog eat?" are kind of two very different questions. :)
Many people feed raw or cooked diets to their dogs consisting of human food. Many of my friends get their dogs' food at the butcher counter - not the dog super store. I, personally, feed kibble to my dogs, supplementing it with supplements for their individual super-active lifestyles. The only human food my dogs get are in very small "treat" amounts.
My dogs do get what's called "Salmon Crack" during dog shows. This is a homemade dog treat that is so good, it's "crack" (a common US term for an addictive drug) for dogs. :)
Salmon Crack is simply a can of salmon, flour and two eggs combined, spread on a cookie sheet and baked. My dogs LOVE it.
But on a regular basis, my dogs do not get human food.
