Alcoholic beverages Can cause intoxication, coma, and death.
Baby food Can contain onion powder, which can be toxic to dogs. (Please see onion below.) Can also result in nutritional deficiencies, if fed in large amounts.
Bones from fish, poultry, or other meat sources Can cause obstruction or laceration of the digestive system.
Cat food Generally too high in protein and fats.
Chocolate, coffee, tea, and other caffeine Contain caffeine, theobromine, or theophylline, which can be toxic and affect the heart and nervous systems.
Citrus oil extracts Can cause vomiting.
Fat trimmings Can cause pancreatitis.
Grapes and raisins Contain an unknown toxin, which can damage the kidneys.
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.
Large amounts of liver Can cause Vitamin A toxicity, which affects muscles and bones.
Macadamia nuts Contain an unknown toxin, which can affect the digestive and nervous systems and muscle.
Milk and other dairy products 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 or spoiled food, garbage 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 (raw, cooked, or powder) Contain sulfoxides and disulfides, which can damage red blood cells and cause anemia. Cats are more susceptible than dogs. Garlic is less toxic than onions.
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 may lead to electrolyte imbalances.
Sugary foods Can lead to obesity, dental problems, and possibly diabetes mellitus.
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.

Acetaminophen (Tylenoltm) -In people, Tylenol is generally a safe and useful painkiller. Dogs (particularly small dogs) are also susceptible to significant tissue damage from as little as two regular strength Tylenol and repeated doses increase the risk significantly. Signs develop quickly and can include salivation, vomiting, weakness and abdominal pain.

Due to the significant toxicity to pets in relatively minimal dosages, the recommendation is clear - Tylenol should not be given to dogs or cats. Other, safer, drugs are available for pain relief; talk to your veterinarian about your own pet's specific needs.

NSAIDs: Aspirin, Ibuprofen, Phenylbutazone, Naproxen These pain relievers cause signs of poisoning by decreasing the mucous production in the stomach. Mucous serves to protect the stomach from the acids it secretes and reduction in mucous production decreases the protection the stomach has from acid secretion and increases the likelihood of ulcer formation. In addition these drugs indirectly decrease the blood flow to vital organs, particularly the kidney, and can result in significant kidney damage. Two regular strength aspirin in a small dog can cause clinical signs of poisoning. As with Tylenol, cats are more sensitive to these drugs and should never be given these medications unless under the specific direction of a veterinarian.
