It's a general reference for a common food, and it can't account for your pet's size, age, health conditions, medications, or how much they actually ate. Toxicity is almost always about dose. If your pet has eaten something you're worried about — or is showing any symptoms — call your veterinarian, an emergency animal hospital, or a poison control hotline right away. Never induce vomiting unless a veterinary professional tells you to.
