Meals that you should never give to a dog

Dogs metabolize food very differently than humans, for this reason many of the foods that are harmless to us are not always healthy for our beloved dogs. And is that many of the things you eat daily (and even give it to try) can be really harmful to your health. The list of problems they may have when eating foods that are harmful to them range from vomiting, bowel problems, nervous system failure, and even death.

Before giving your dog the leftovers of your food you should know what are the foods that can significantly affect your health. Next we give you a list, as complete as possible, so that you have in mind when feeding a dog. Keep reading and you will discover the foods that you should never give to a dog .


Chocolate contains theobromine, an alkaloid that increases the heartbeat, stimulates the central nervous system and constricts the arteries. After 4 to 6 hours of chocolate intake, your dog may have symptoms such as vomiting, diarrhea, hyperactivity, excitability, heart failure and heart attacks that can lead to death.

That your dog eat a piece of chocolate will not hurt you but you must control that you do not eat the whole tablet, if so you should take it to the vet.


The onion contains high amounts of a substance called thiosulfate that damages the red blood cells of your blood, which brings fatal consequences for our pet since it causes weakness, anemia and serious respiratory problems.


Like onion, garlic is a product that you should not put in your dog's food contains thiosulfate, but in smaller amounts. We must keep our dogs and cats away (it is also harmful in them) from both garlic and onion, and in case of accidental intake should be taken to the vet.

Avocado or avocado

The avocado contains persin, a toxic substance that can cause stomach pains, vomiting and even pancreatitis in our dog. This substance is not only in the pulp of the avocado, but also in the husk and leaves.

Grapes and raisins

Grapes and raisins are toxic to dogs because they cause kidney failure that can lead to death. Do not let your dog eat grapes and if at any time you drop one or two on the floor, always try to lift them, so you will avoid eating them.

Potatoes or potatoes

The starch contained in potatoes (potatoes) is not easy to digest for dogs, so their intake causes digestive problems . In addition, the husk, stem and leaves of potatoes or potatoes contain solanine, a natural poison that causes flaws in the digestive and nervous system of dogs, which leads to death.

Nuts and nuts in general

Nuts, like many nuts, contain large amounts of phosphorus that is detrimental to the health of the dog, as it causes gallstones (stones) . In addition, it affects the muscle system of the dog causing muscle tremors, weakness and paralysis in the hind legs.

Dairy products

Once the puppies go on to adulthood, they become lactose intolerant to dairy products. Lacking the enzymes needed to digest lactose in dairy products, they cause vomiting, diarrhea and gastrointestinal problems.


Tomatoes that are not ripe have a high content of solanine, of which we have already spoken previously (natural poison). Also, they are too acidic for dogs.


Bones, raw or cooked, are bad for dogs . Not because of the nutritional content itself, but because dogs love to chew them, break them and therefore they can go through, get stuck, crack or splinter and get to pierce the intestine or stomach.

To give a bone make sure it is a bone prepared for dogs (milk, cartilage, or some soft). You should also take into account if the dog is used to eating bones since childhood, if it is, you could consider giving bones but with great caution. What you should never give are chicken bones or turkey, these bones are hollow and if they break in the stomach of the dog can seriously damage your digestive system.

Avoid giving these foods to your pet and it will grow healthy and strong. Good luck with your best friend.
