List of prohibited foods for dogs
Before starting to list some harmful foods for dogs, it is important to note that not all of them are especially harmful. In fact, on this AnimalWised list you will find ingredients that can cause long term damage if their consumption is abused, while others are considered food mortal for dogs in very low doses, so its consumption should be avoided in any case. Review well the notes of each of the foods that we will show you to know what their degree of toxicity is:
We start the list of forbidden foods for dogs with a classic, the onion (Allium cepa), without a doubt one of the foods that we should completely exclude from the dog's diet since it is a potentially toxic food. Its allicin content is released after chewing and the degrading substance, n-propyl disulfide, causes oxidative damage to the cell membranes of erythrocytes, breaking within the blood vessels and causing hemolytic anemia  .
We should not be concerned if our dog has accidentally eaten a small dose of onion, however, continuous ingestion causes Gastrointestinal disorders and, in the most acute cases, the appearance of jaundice due to hemolysis. For every 15 grams per kilo of dog weight we can begin to observe symptoms of toxicity in the dog. Symptoms of onion poisoning usually go unnoticed, but we may notice vomiting, weakness and a change in the color of the dog's mucous membranes..
2. Coffee, tea and chocolate
The coffee, the tea and the chocolate have in common methylxanthine, a stimulating alkaloid that acts directly on the dog's central nervous system. In coffee we find caffeine, in tea theophylline and in chocolate theboromine, all of them toxic substances in large quantities. We could also include other alkaloids in this section, such as those present in cola soft drinks..
The xatinas, in addition to affect the CNS They can impair the functioning of the kidneys, the cardiovascular system, smooth muscle and skeletal muscle. Although there are dogs more sensitive than others to methylxanthine, the truth is that 100 grams of dark chocolate in a medium-sized dog they can be fatal. It is one of the most serious toxic dog foods.
The most common symptoms of methylxanthine poisoning are vomiting, diarrhea, incontinence, and tremors. The most recommended is induce the dog to vomit before two hours.
The avocado (Persea americana) is undoubtedly one of the best-known forbidden vegetables for dogs, due to its content in persina, a fungal toxin derived from fatty acids. Its level of toxicity is mild in dogs and cats, however, in other animals it can cause serious symptoms, especially in birds and ruminants..
The toxin is found only on the bone and on the leaves of the plant, but not in the meat of the vegetable. After consumption we can observe vomiting, diarrhea, lack of stool production and, in the most severe cases, the development of a pancreatitits (inflammation of the pancreas). The highest risk of avocado consumption occurs due to obstruction of the bone in the esophagus.
As with the onion, the Garlic (Allium sativum) contains allicin, which could also cause the appearance of hemolytic anemia before a regular and excessive consumption. It is another of the prohibited foods for dogs. However, unlike onion, garlic has been studied and found to be potent antibiotic effects, antifungals, antiparasitics and enhancers of the immune and cardiovascular system of the dog.
Although it is a food that is preferable to avoid, especially in dogs that suffer from immune, digestive problems or allergies, the consequences or benefits of consuming this product can vary greatly depending on the individual, their genetics, the dose, etc. Faced with garlic poisoning we would observe the same symptoms as in onion poisoning.
In any case, before using garlic for dogs It is advisable to always consult with the veterinarian to help us find a safe dose for our best friend that allows us to offer him all the benefits without the risk of developing health problems.
Many people who make homemade diets for dogs use the Salt as an additional condiment, however, a high consumption of sodium chloride can lead to the dehydration of the dog, aggravate cardiac and renal pathologies or cause intoxication. Remember that salt is the most used product to induce a dog to vomit. Symptoms of salt poisoning would be vomiting, internal bleeding, incoordination, diarrhea, polydipsia and polyuria (constant urge to drink and urinate), seizures and shock. It is one of the toxic foods for dogs that more people include in their animal's diet without being aware.
6. Macadamia nuts
The macadamia nuts (Macadamia integrifolia) are a fruit of a proteaceous shrub. Its consumption causes intoxication and there are several studies that demonstrate toxicity of this fruit, whether eaten raw or roasted. It is one of the harmful foods for dogs. Macadamia nuts directly affect the dog's CNS and act abruptly 24 hours after ingestion. Clinical symptoms include depression, vomiting, ataxia, tremors, abdominal pain, stiffness, and pale or anemic mucous membranes are easily seen. Although the initial effects are serious, the consumption of Macadamia nuts not deadly .
7. Grapes and raisins
The grapes and the raisins They are rich in linoleic acid (as well as other fatty acids), however studies agree that some component of this fruit, present in variable amounts, or some extrinsic compound causes renal insufficiency. It is one of the most dangerous and unknown prohibited foods for dogs.
It can be observed that dogs that ingest grapes or raisins show a higher concentration of blood urea nitrogen and serum creatinine. The most toxic part of grapes is undoubtedly the seeds, although it is recommended to discard the fruit completely from the dog's diet.
Symptoms of a poisoning from grapes or raisins are vomiting, diarrhea, lethargy, ataxia, polyuria and weakness. The main problem with the consumption of these foods is that the mechanism that causes the internal injuries.
The alcohol It is present in our diet and its negative effects on the body are multiple and known, affecting the CNS and causing severe liver damage. Our dog can consume it by accident due to alcoholic bottles, perfumes, mouthwash and even after ingestion of Rotten apples.
Alcohol can also cause alcohol intoxication very easily.

The yeasts or ferments Conventional cakes and recipes that we use to make cakes and other recipes contain Saccharomyces cerevisiae, a unicellular fungus quite harmful. Either by ingesting uncooked bread dough or directly from yeast, we can cause intoxication in our dog. The most frequent symptoms are the appearance of gas, vomiting, diarrhea, malaise and lethargy.

10. Cooked bones
Another of the prohibited foods for dogs are cooked bones. Whether from a broth, from a recipe made in the oven or on the grill, the cooked bones should never be offered to dogs, as they can cause tooth breakage. As well they chip easily, so we could cause an obstruction of the windpipe, injuries and perforations, tears and many other internal injuries. To avoid this we will always bet on offering raw and meaty bones.
In the case of american black cherry (Prunus serotina) or virginia cherry (Prunus virginiana) we must be very careful, because although dogs and cats can consume the meat of fruits, we must completely avoid seeds, leaves and stem, which are considered toxic food for dogs, due to their content in cyanide. Its toxicity varies from mild to moderate and various symptoms may appear after consumption, such as dilated pupils, difficulty breathing, red gums, shock and even death..
As you know, the consumption of certain species of mushrooms can intoxicate humans, as well as dogs, thus becoming one of the deadly foods for dogs. We speak especially of the mushrooms belonging to the genera Amanita, Galerina and Lepiota, but there are many more. The most characteristic symptoms of intoxication are: drooling, vomiting, diarrhea, incoordination, sluggishness, tremors, seizures and, in the most severe cases, a multi-organ failure and even death.
If your dog has consumed a fungus of which you do not know its toxicity, get the remains or another that is nearby (with caution, always through a plastic bag or similar) and go urgently to a veterinary center. Some mushrooms work between 15 and 30 minutes, while others take longer.

However, we must know that tremorgenic mycotoxins in moldy food are one of the bad foods for dogs. They can be found in bread, pasta, cheese, nuts, and even compost. Symptoms include drooling, vomiting, agitation, incoordination, tremors, seizures and, in the most severe cases, can cause liver failure.
