1 onion
The onion is undoubtedly 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 substance that degrades, n-propyl disulfide, causes an oxidative lesion in the cell membranes of erythrocytes, breaking into blood vessels and causing hemolytic anemia .
We should not worry if our dog has eaten a small dose of onion by accident, however, continuous ingestion causes gastrointestinal problems and, in the most acute cases, the appearance of jaundice due to hemolysis.For every 15 grams per kilogram of the dog's 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 mucous color of the dog.
2.Coffee, tea and chocolate
coffee , te and chocolate have in common methylxanthine , a stimulating alkaloid that acts directly on the central nervous system of the dog.In the cafe we find caffeine, in the tea theophylline and in chocolate theboromine, all of them toxic substances in large quantities.We could also include in this section other alkaloids, such as those that are present in cola drinks.
Xatinas, in addition to affecting the CNS can impair kidney function, cardiovascular system, smooth muscle and muscle striated.Although there are dogs more sensitive than others to methylxanthine, the truth is that 100 grams of dark chocolate in a medium-sized dog can be fatal .
The most frequent symptoms In a poisoning of methylxanthine are vomiting, diarrhea, incontinence and tremor.The most advisable is to cause the vomit of the dog before two hours.
3.Avocate
The avocado is undoubtedly one of the best known vegetables for dogs, due to its high content of persina , a fungicidal toxin derived from fatty acids.Although it is indeed a very dangerous substance for the consumption of dogs, the truth is that the toxin is only in the bone and in the leaves of the plant, but not in the meat of the vegetable.The persina can cause damage to the myocytes of the heart and kidneys, and in the most severe cases it can cause the death of the dog.
The most obvious symptoms of avocado poisoning would be vomiting, dyspnea or enlarged abdomen due to ascites.
4.Garlic
As with onions, garlic (also belonging to the Allium genus) contains allicin, which could cause the appearance of hemolytic anemia However, unlike onions, garlic has been the subject of study and powerful antibiotic effects , antifungal, antiparasitic and potentiators of the dog's immune and cardiovascular system have been discovered.
Although it is a food that is preferable to avoid, especially in dogs that suffer from immune, digestive or allergic problems, the consequences or the benefits of the consumption of this product can vary greatly depending on the individual himself, his genetics, the dose, etc.a garlic poisoning we would observe the same symptoms as in onion poisoning.
5.Salt
Many people who make homemade diets use salt as another condiment, however, a high consumption of sodium chloride can lead to dehydration dog, aggravate cardiac and renal pathologies or cause a intoxication: Remember that salt is the most commonly used product to induce a dog to vomit.
The symptoms of salt poisoning would be vomiting, internal bleeding, uncoordination, diarrhea, polydipsia and polyuria (desire to drink and constant urination), convulsions and shock.
6.News of Macadamia
The Macadamia nuts are a fruit of a proteaceous bush.Its consumption causes poisoning and there are several studies that demonstrate the toxicity of This fruit, whether consumed raw or roasted.Macadamia nuts directly affect the dog's CNS and act sharply after 24 hours of ingestion.
Clinical symptoms include depression, vomiting, ataxia, tremor, pain abdominal, stiff, and pale or anemic mucous membranes are easily observed.Although the initial effects are severe, the consumption of Macadamia nuts is not fatal .
7 grapes and raisins
The grapes and the raisins are rich in linoleic acid (as well as in other fatty acids), however studies agree that some component of this fruit , present in varying amounts, or some extrinsic compound causes renal failure .
It can be seen that dogs that ingest grapes or raisins show a higher concentration of urea nitrogen in blood and creatinine Serica.The most toxic part of the grapes is undoubtedly the seeds, although it is recommended to discard the fruit completely from the dog's food.
The symptoms of a intoxication by 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 internal injuries is not known.
8 alcohol
The alcohol is present in our diet and its negative effects on the body are multiple and known, affecting the CNS and causing serious liver damage .The dog can consume it by accident due to alcoholic bottles, perfumes, mouthwashes and even after ingestion of rotten apples .
Alcohol can also cause an ethyl poisoning with great ease.Without a doubt, it is necessary to completely discard offering this product to our dog and in case of accidental ingestion it is necessary to go immediately to a veterinary center .
9 yeasts and ferments
The conventional yeasts or ferments that we use to make cakes and other recipes contain Saccharomyces cerevisiae, a unicellular fungus quite harmful.Either by ingestion of Uncooked bread dough or directly from yeast, we can cause poisoning in our dog.The most frequent symptoms are the appearance of gas, vomiting, diarrhea, discomfort and lethargy.
10 cooked bones
We will finalize this list of the 10 toxic dog foods by mentioning cooked bones .Whether it's a broth, a recipe made in the oven or grilled, cooked bones should never be offered to dogs, as they can cause teeth breakage.
They also splinter easily , so we could cause a blockage of the trachea, injuries and perforations, tear and many other injuries.To avoid it, bet on raw and fleshy bones.
