What Human Foods Are Toxic to a Dog?

Dogs are ominovorous, but that does not mean that they can eat anything. In fact, some common human foods are toxic to dogs. And although some of the most common foods in the kitchen can kill a dog, some human foods given as treats are actually very nutritious, such as carrots and broccoli. It's important to know which foods your dog can share with you.

  1. Caffeine is Dangerous

    • Although a tasty treat for people, chocolate can be fatal for a dog.

      One of the most dangerous toxins for dogs is caffeine, which is found in coffee, tea, soda and chocolate. Caffeine can affect the heart and the nervous system. An overdose of caffeine can actually be fatal for a dog. Chocolate, tea and soda also contain theobromine, which can cause irregular heartbeat, seizures and death.

    Not All Fruits and Vegetables are Healthy for Dogs

    • Grapes are toxic for dogs and can cause kidney failure.

      Fruits and vegetables are good for people, and some are very nutritious for dogs. But some common fruits and vegetables can be toxic. Grapes and raisins should never be fed to dogs, as they can damage the kidneys. The vegetable list is even longer: Mushrooms, onions, avocados and garlic are all poisonous to dogs. In addition, the leaves and stems of potatoes, tomatoes and rhubarb can often cause severe damage to the digestive, nervous and urinary systems.

    Deadly Poisons in the Pantry

    • Alcohol in any form can be fatal to dogs.

      Many other foods can make a dog sick, but it's important to know which ones are lethal. Alcohol and tobacco in any form can cause comas and death. Macadamia nuts and nutmeg, both seemingly harmless foods, can be fatal for dogs. Raw fish fed regularly can cause thiamine deficiencies, eventually resulting in death.

    Sugar, Salt and Fat: Bad for Dogs

    • Avoid human sweet treats; stick to dog biscuits.

      The most common foods that cause illnesses in humans also cause illness in dogs. While it can be tempting to feed dogs table scraps, the sugar, salt and fat in many foods can cause long-term, chronic problems in dogs, such as obesity, diabetes and pancreatitis. While many of these conditions are not acutely fatal, long-term chronic conditions can ultimately shorten a dog's life or lead to life-threatening conditions.
