Toxic Foods For Dogs?

Hi, does anyone here own a dog and know about toxic foods that dog's should not eat? We got a new puppy a month ago and my little sister who is only 5 gave our puppy some of her raisins, we didn't know that it was bad for dogs. Our pup became sick but he's better now coz we got him treatment. I'm so worried now that he might eat things that are bad from him. I'm doing research now to make sure I know everything I need to know about what's bad for my puppy, so far I found these things are bad:

chocolate (all kinds), cocoa powder, onions, garlic, mushrooms, raisins, grapes, macadamia nuts

if anyone here knows about other things, please let me know!! Please!
