Quick answer: Most dog poisonings happen at home and are preventable. The most common toxins are human medications, foods like chocolate, grapes, and xylitol, rodent baits, household and garden chemicals, and plants. Store medications and chemicals securely, keep toxic foods out of reach, use pet-safe pest control, and save poison hotline numbers in your phone.
