Even common foods like grapes, onions, tomatoes, and avocados can be toxic to dogs, causing anything from stomach upset to death. Here's what you need to know.

Citrus oil extracts - Can cause vomiting.
Dairy products - Can cause pancreatitis, gas and diarrhea. A small amount of non-fat, plain yogurt is usually safe.
Eggs (raw) - Can cause hair loss, weakness, growth retardation or skeleton deformity. Raw eggs can also contain Salmonella.

Fruit pips and seeds - Many fruits seed contain cyanide, which is poisonous to dogs and humans alike if you chew the seeds in number.
Grains - Large amounts of grain leads to poor nutrition.
Grapes and raisins - Can cause kidney failure and death in dogs—either in small amounts over time or even in a single serving.
Ham and bacon - Too much fat and salt can cause pancreatitis.
