Human foods harmful and/or poisonous to your dog

How many times have we all given our dog a little food off of our own plate, or put a small amount of our food into their bowl at feeding time. Listed below are numerous reasons why this is not such a good idea. Food for thought, if you can excuse the pun.

  • Avocado: All parts are toxic to dogs.
  • Chocolate: Contains Theobromine, a cardiac stimulant which can be fatal to dogs.
  • Fruit Pits and Seeds: Most contain cyanide.
  • Garlic: Contains Thiosulphate, though a small amount, so a lot would have to be ingested to be toxic. Keep in mind; it builds up in the system.

  • Grapes: Affects a dog's kidneys.
  • Macadamia Nuts: Affects the nervous system.
  • Mushrooms: Affect the nervous system, kidneys and heart.
  • Nutmeg: Can cause seizures and central nervous system damage.
  • Onions: Contains same toxin as garlic, though in much larger amounts.
  • Raisins: Same as grapes.
  • Sugar-Free Foods: These contain Xylitol, which can cause liver failure in dogs.
  • 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 (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, Tea, Soft Drinks (Coffee, tea, & most soft drinks are dangerous due to the caffeine).
  • Beer/Wine/Alcohol of any kind (Alcohol of any kind could lead to coma or 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).
  • Mouldy or Spoiled Food (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 poisoning).
  • 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).
  • Excessive Fatty Foods (Excess fatty foods can cause Pancreatitis).
  • Ham & bacon (Contain too much fat and too much salt, and can cause pancreatitis. Also, large breeds of dogs that eat salty food may drink too much water and develop a life-threatening condition called bloat. This is where the stomach fills up with gas and within several hours may twist, causing death).
  • Liver in large amounts (Raw liver or too much cooked liver (three servings a week) can lead to vitamin A toxicity. This can affect muscles and cause deformed bones, excessive bone growth on the elbows and spine, weight loss, and anorexia).
  • Walnuts (Walnuts are poisonous to dogs).
