Foods poisonous to dogs

I recently learned that Lynnis and Brian's dog Runcible Spoon is quite ill with liver failure from eating onions. Hopefully, Lynnis will keep us updated on that. I looked up foods poisonous to dogs and they include:

• Onions
• Chocolate
• Xylitol sweetener
• Mushrooms
• Grapes fresh or dried (raisins)

I'm always learning something new.
