Food:
Alcoholic Beverages - Can cause intoxication, coma, and death.

Bones from fish, poultry, or other meat sources - Can cause obstruction or laceration of the digestive system.
Cat food - obviously ok for cats, but not for dogs - it's too high in protein and fats to be fed on a regular basis for dogs
Chocolate - Contain caffeine, theobromine, or theophylline, which can be toxic and affect the heart and nervous systems.
Coffee - See chocolate
Tea - See chocolate
Anything with caffeine - See chocolate
Citrus oil extracts - Can cause vomiting.
Fat trimmings - Can cause pancreatitis.
Grapes and Raisins - Contain an unknown toxin, which can damage the kidneys. There have been no problems associated with grape seed extract.
Hops - Unknown compound causes panting, increased heart rate, elevated temperature, seizures, and death.
Human vitamin supplements containing iron - Can damage the lining of the digestive system and be toxic to the other organs including the liver and kidneys.
Macadamia nuts - Contain an unknown toxin, which can affect the digestive and nervous systems and muscle.
Marijuana - Can depress the nervous system, cause vomiting, and changes in the heart rate.
Milk - Some adult dogs and cats do not have sufficient amounts of the enzyme lactase, which breaks down the lactose in milk. This can result in diarrhea. Lactose-free milk products are available for pets.
Moldy/spoiled food - Can contain multiple toxins causing vomiting and diarrhea and can also affect other organs.
Mushrooms - Can contain toxins, which may affect multiple systems in the body, cause shock, and result in death.
Onions and garlic - Contain sulfoxides and disulfides, which can damage red blood cells and cause anemia. Cats are more susceptible than dogs.
Persimmons - Seeds can cause intestinal obstruction and enteritis.
Pits from peaches and plums - Can cause obstruction of the digestive tract.
Potato, rhubarb, and tomato leaves. Potato and tomato stems. - Contain oxalates, which can affect the digestive, nervous, and urinary systems. This is more of a problem in livestock.
Raw eggs - Contain an enzyme called avidin, which decreases the absorption of biotin (a B vitamin). This can lead to skin and hair coat problems. Raw eggs may also contain Salmonella.
Raw fish - Can result in a thiamine (a B vitamin) deficiency leading to loss of appetite, seizures, and in severe cases, death. More common if raw fish is fed regularly.
Salt - If eaten in large quantities it may lead to electrolyte imbalances.
String - Can become trapped in the digestive system; called a "string foreign body."
Sugary foods - Can lead to obesity, dental problems, and possibly diabetes mellitus.
Table scraps - Table scraps are not nutritionally balanced. They should never be more than 10% of the diet. Fat should be trimmed from meat; bones should not be fed.
Tobacco - Contains nicotine, which affects the digestive and nervous systems. Can result in rapid heart beat, collapse, coma, and death.
Yeast dough - Can expand and produce gas in the digestive system, causing pain and possible rupture of the stomach or intestines.
Xylitol (an artificial sweetner) - Can cause liver failure.
