We feed Punkin a whole bunch of different things:
lamb, chicken, beef (anykind), turkey
Veggies (, peppers, yellow/green beans, peas etc)
Fruit (strawberries, raspberries, blueberries, banana, apple etc)
Whole Wheat pasta, brown rice, home cooked plain oatmeal, potatoes (cooked only), sweet potatoes
We don't feed citrus fruit, pork, onions, grapes, mushrooms
Garlic only in small small quantities as it's from the onion family
Small quantities of brocoli and cauliflower every once in a while
I have recently started giving her small amounts of cottage cheese and plain yogurt (started at 1/4 of a teaspoon a day and now give 1 teaspoon twice a day), also a small pich of salt and a 1/4 teaspoon of canola oil twice daily.
We currently (at vet's advice) give her 1/3 meat, 1/3 starch, 1/3 fruits/veggies. The physical amount varies, depending on her activity level that day.
There are a whole bunch of different views on the subject, and many books.
What we are doing is really working well for our furbaby (who is 10.5 months)
I usually freeze enough food for a week or two so it doesn't feel like I'm always cooking for the dog. Also I save some of our unseasoned food for her as well.
This is probably more info than you were looking for, but once I started typing I couldn't stop.
