Are there any specific fruits dogs shouldn't have?

I'm getting very interested in breed specific diets (natural raw diets, not royal canin!) and one of the things specifically mentioned for chihuahuas are tropical fruits, and my pup is half chi. I know to stay away from grapes, raisens, fruit seeds, tomatoes, avocado, etc. as well as veggies like onions or peppers. I'm most interested in superfoods like acai, noni, mangosteen, etc. I WILL be asking her vet before giving her any given fruit, but wanted to at least have a general idea first. I recall hearing pomegranate was dangerous?
