25 Human Foods Toxic To Dogs

• Onions (Both onions and garlic contain the toxic ingredient Thiosulphate. But onions are more of a danger. Many dog biscuits contain *small* amounts of garlic – garlic contains less of this toxin so huge amounts would need to be consumed to be toxic. And, by the way, this poison builds up the system – it can be toxic in one large dose – or with repeated consumption of small amounts.)
  
  
• Chocolate (Chocolate contains Theobromine, a compound that is a cardiac stimulant and a diuretic. This can be fatal to dogs.)
  
• Grapes (Grapes are dangerous because of an unknown substance which is toxic to dogs – affects canine’s kidneys)
  
• Raisins (See above.)
  
• Most Fruit Pits and Seeds (Contain Cyanogenic Glycosides resulting in cyanide poisoning – though the fruit itself is OK.)
  
• Macadamia Nuts (Macadamia nuts contain an unknown substance that is toxic to dogs.)
  
• Most Bones should *not* be given (especially chicken bones) because they can splinter and cause laceration of the digestive system and/or become lodged in your pet’s throat – so they also pose a choking hazard.
  
  
• Potato Peelings and Green Potatoes (Contain Oxalates, which can affect the digestive, nervous, and urinary systems.)
  
  
• Rhubarb leaves (see above)
  
  
• Broccoli (Broccoli is only toxic in large quantities.)
  
  
• Green parts of Tomatoes or Green Potatoes(Contain oxalates, which can affect the digestive, nervous, and urinary systems.)
  
• Yeast Dough (Yeast Dough can produce gas and swell in your pet’s stomach – leading to rupture of the digestive system)
  
• Coffee/Coffee Grounds and Tea ( are dangerous due to the caffine.)
  
• Beer/Wine/Alcohol of any kind (Alcohol of any kind could lead to coma or even death.)
  
• Human Vitamins (Human vitamins, especially those containing iron, can cause damage to the lining of the digestive system as well as cause kidney and liver damage)
  
• Moldy or Spoiled Food (though I think this goes without saying.)
  
• Persimmons (Persimmons can cause intestinal blockage)
  
• Raw Eggs and Raw Fish (Raw eggs and some raw fish can cause Salmonella poisening.)
  
  
• Salt, Baking Soda, Baking Powder (In large amounts these can cause an electrolyte imbalance – and severe electrolyte imbalances can lead to muscle spasm or even congestive heart failure.)
  
  
• Mushrooms (Mushrooms may contain toxins which could cause liver and kidney damage)
  
  
• Sugar-Free Foods (Sugar-free foods containing Xylitol have been found to cause liver failure in some dogs.)
  
• Nutmeg (Nutmeg can cause tremors, seizures, and central nervous system damage.)
  
• Excessive Fatty Foods (Excess fatty foods can cause Pancreatitis.)
  
  
• Avocado (All parts of the avocado and avocado tree are toxic to dogs.)
  
• Diary Products (Dairy products don’t usually pose a great danger; but many dairy product have high fat content (see number 23) – and many pets are lactose intolerant – some pets more than others. Lactose intolerance leads to gas and diarrhea; though small amounts of yogurt and cheese are usually fairly well tolerated.)
