You might think that giving your four-legged friend all the leftovers that his heart desires will make him happier, but feeding him certain human foods can cause stomach upset, diarrhea, serious health issues or even death.
If you suspect your pet may have eaten a dangerous food, contact your veterinarian immediately. In many cases, early recognition and treatment are critical.

Xylitol is an artificial sweetener found in products such as gum, candy, mints, toothpaste, and mouthwash. Xylitol is harmful to dogs because it causes a sudden release of insulin in the body that leads to hypoglycemia (low blood sugar). Xylitol can also cause liver damage in dogs. Within 30 minutes after eating, the dog may vomit, be lethargic (tired), and/or be uncoordinated. However, some signs of toxicity can also be delayed for hours or even for a few days. Xylitol toxicity in dogs can be fatal if untreated. It is unknown whether xylitol is toxic to cats.
Chocolate, Coffee, and Caffeine
Chocolate contains theobromine, a chemical that is toxic to dogs in large enough quantities. Chocolate also contains caffeine, which is found in coffee, tea, and certain soft drinks. Different types of chocolate contain different amounts of theobromine and caffeine. For example, dark chocolate and baking chocolate contain more of these compounds than milk chocolate does, so a dog would need to eat more milk chocolate in order to become ill. However, even a few ounces of chocolate can be enough to cause illness in a small dog, so no amount or type of chocolate should be considered safe for a dog to eat. Chocolate toxicity can cause vomiting, diarrhea, rapid or irregular heart rate, restlessness, muscle tremors, and seizures. Death can occur within 24 hours of ingestion.
