All good questions. Let me tackle them separately.
Exploring the idea of a homemade diet for your pup is fine. It can be a healthful way to feed. (but so can good kibble--one isn't necessarily better than the other.) There are lots of resources on line. The one we often send people to is http://www.rawdogranch.com
which is the personal website of one of the moderators of this forum, Lauri. It's a good step-by-step how to for those already commited to feeding a raw diet.
But a home-prepared canine diet is MUCH different than just "feeding her what we eat." Dogs arent' people, of course, so their nutritional needs are very different. While a vegetable-based diet can actually be very healthy for people, it's not what dogs need. Your instinct about the diet being mostly meat is closer to the right thinking. But think whole raw carcasses of meat AND bone, rather than just meat.
Fruits and vegetables can be added to a canine diet, but not raw. Dogs don't have the digestive enzymes to break down cellulose, so you either need to cook, puree, or freeze vegetables to make them digestible to dogs. Of course, if you're just giving the dog a bite of raw carrot or apple as a treat, that's cool. But don't count that as part of his overall nutrition. It'll just pass through largely unused.
Hope this helps. You can tell from my moderator tag that I personally am a fan of raw diets for dogs. But it does take a bit of doing, at least at first, to understand what constitutes a healthy, balanced, species-appropriate diet for dogs. But there's no reason that a pup as young as yours can start eating his first raw foods immediately.
Good luck. Keep those questions coming.
