As we know, the body of dogs works differently from that of humans. While we can eat practically any type of foods, for them the diet has to be much more limited, since there is a large amount of toxic substances that can easily damage them. Here are some of these dangerous foods for our pets.
1.Chocolate. It contains high levels of fat, caffeine and methylxanthines, among other substances that are really dangerous for the dog. Its ingestion can cause damage to the lungs, heart, kidneys and nervous system of the animal. In large quantities, this food is toxic to the point of causing symptoms such as vomiting, diarrhea, seizures, internal bleeding, heart attacks, and even death. Dark chocolate is the most harmful of all.
2. Onion and garlic. Both contain a substance called thiosulfate, which in dogs causes stomach and respiratory problems, loss of appetite, and blood in the urine, among other symptoms. Furthermore, this substance destroys the dog's red blood cells, causing severe hemolytic anemia.
3. Walnuts. Nuts, in general, are not recommended for dogs, due to their high phosphorus content. They lead to vomiting, joint swelling, hypothermia, dizziness, fever, and bladder stones. In more severe cases, it can lead to severe paralysis. Macadamia nuts are the most poisonous.
4. Dairy. Many adult dogs are lactose intolerant, since they are not capable of producing lactase, an enzyme located in the small intestine responsible for dogs and humans to digest dairy products. In the dog they can cause serious digestive problems.
5. Grapes and raisins. Not all dogs have negative reactions to these foods, but for some of them they can be really harmful. Intolerance towards them causes symptoms such as weakness, dehydration, spasms, vomiting, diarrhea, even death.
These are just some examples of the foods that are most dangerous for our dog, although there are many moreWe can also mention others such as coffee, bones, some fruits, salt, or baking dough. If you have any questions, it's best to ask a veterinarian for advice on the ideal diet for your pet.

Toxicity depends on the ingested dose, the size of the dog and the time until receiving care.
