Why are these Foods Harmful to Dogs – a Detailed Explanation

While many human foods are safe for dogs to consume, there are some that can be toxic and cause serious health issues if ingested. These harmful foods can include chocolate, grapes and raisins, onions and garlic, avocado, macadamia nuts, and alcohol, among others.

It is crucial to keep these foods out of reach of dogs and to seek veterinary care if you suspect your dog has ingested any of these toxic substances. By understanding which foods can be harmful to our dogs and why, we can help keep them happy and healthy.

  1. People’s food: People’s food (high in sugars, fats, and salt). While it might seem like everything is “people’s food,” – Remember that these types of foods often contain higher levels of fats, sugars, and salt than dogs are used to.

    This can lead to electrolyte imbalances, obesity, digestive problems, liver dysfunction, and pancreatitis. Many seemingly harmless human foods can also be toxic to pets – so it’s always a good idea to do a quick internet search before feeding your dog anything that you’re eating.

  2. Raw eggs: While eggs are a great source of protein and can be beneficial for your dog’s coat and digestive system when cooked properly – they can be toxic when given raw. This is because raw eggs contain an enzyme called “avidin,” this enzyme can lead to a biotin deficiency in dogs. Biotin is a B-Vitamin that is important for healthy skin, coat, and digestion.

    A deficiency of Vitamin B can lead to problems such as an unhealthy coat, digestive issues, and skin problems. Raw eggs can also carry salmonella – which is highly poisonous to dogs.

  3. Milk and other dairy products: Milk and dairy products have a high calcium content. They can also be harmful to dogs. Many dogs are lactose intolerant; which can cause digestive problems such as gas, bloating, abdominal pain, and diarrhea. Some dogs may be able to tolerate plain yogurt or cheese – it’s best to be cautious and avoid giving them large amounts of dairy products.

  4. Human vitamins containing iron: Iron supplements designed for humans can be harmful to dogs and can damage their digestive system, kidneys, and liver. Use supplements that are specifically designed for dogs to ensure their safety.

  5. Large quantities of liver: Eating large amounts of liver can result in Vitamin A toxicity – which can affect a dog’s muscles, bones, and overall health. Symptoms of vitamin A toxicity include deformed bones, extra bone growth, anorexia, and more.

  6. Mushrooms: Mushrooms contain a variety of toxins that can affect many parts of a dog’s body. They can cause seizures, shock, and even death.

  7. Macadamia nuts: Macadamia nuts contain toxins that can cause vomiting, muscle and joint pain, swelling, and lethargy in dogs.

  8. Grapes and raisins: Studies have shown that grapes and raisins contain a toxin that can damage a dog’s kidneys and lead to kidney failure and even death. It’s not clear what chemical in these foods is responsible for this effect, but it’s best to avoid giving them to your dog.

  9. Alcohol: Even small amounts of alcohol can be harmful to your Dog, Alkohol can cause vomiting, diarrhea, difficulty breathing, tremors, and even death.

  10. Chocolate: Chocolate contains theobromine, which can be toxic to dogs. The amount of theobromine that is toxic depends on the type of chocolate and the size of the dog. Dark chocolate and unsweetened baker’s-chocolate contain higher amounts of theobromine and are more toxic than milk chocolate.

    The Symptoms of chocolate poisoning include vomiting, diarrhea, rapid breathing, increased heart rate, and tremors. In severe cases, it can lead to: Seizures, coma, and even death. It’s best to keep all chocolate products out of the reach of your dog.

  11. Onions and garlic: Both onions and garlic contain compounds that can be toxic to dogs, particularly when consumed in large amounts. These compounds can damage a dog’s red blood cells, leading to anemia and other health problems. Symptoms of onion and garlic poisoning may not appear for several days and can include: vomiting, diarrhea, weakness, and breathing difficulties.

  12. Avocado: While avocados are a healthy choice for humans. They can be harmful to dogs. Avocados contain a substance called persin. Persin can cause vomiting and diarrhea in dogs. The pits of avocados can also be a choking hazard for dogs.

  13. Xylitol: Xylitol is a sugar substitute that is often used in sugar-free gum, candy, and other products. It is extremely toxic to dogs and can cause rapid insulin release – leading to hypoglycemia (low blood sugar). Symptoms of xylitol poisoning include vomiting, loss of coordination, and seizures. In severe cases, it can lead to liver failure.

  14. Cooked bones: While it may seem natural to give your dog a bone to chew on, cooked bones can be dangerous. Cooked bones are more prone to splintering – This can cause blockages or tears in a dog’s digestive system. Bones that have been cooked with spices or marinades can also be toxic to dogs.

  15. Fatty foods: While it may be tempting to give your dog scraps from your own meals; it’s important to remember that fatty foods can be harmful to dogs. Foods that are high in fat can cause pancreatitis, a condition in which the pancreas becomes inflamed and unable to function properly. Symptoms of pancreatitis include vomiting, diarrhea, abdominal pain, and loss of appetite.


Be cautious about feeding dogs human foods – be aware of which foods can be toxic to them. If you are unsure whether a food is safe for your dog – it is always best to consult with your veterinarian or do some research to be sure.
