Top Foods That Are Poisonous for Dogs
Are you feeding your dog poisonous food without knowing? Or are you wondering what are the most poisonous foods for dogs? Often, people share their meals with their dogs because, to them, they are like family members. However, just because some foods such as chocolate or milk are suitable for you, they may be intolerant to dogs. Unlike humans, dogs process food differently. This means that most of our food is harmful to our four-legged friends. However, several common foods are poison to dogs. Therefore, we need to differentiate between them and give our pets only what is safe for their health. Here is a detailed look at some of the most poisonous foods for dogs and what to look for in case you suspect that your dog has ingested something poisonous.

What are the Most Poisonous Foods for Dogs?
Some of the most poisonous foods for dogs include:
1. Chocolate
Do you love chocolate carrying chocolate to your home? Well, chocolate contains caffeine-theobromine compounds (especially dark chocolate) that lead to vomits, diarrhea, and convulsions in dogs. Next time you have one in your home, ensure it stays away from your dog.
2. Grapes and Raisins
While they are sweet to humans, grapes and raisins contain toxins that are harmful to dogs. When ingested, dogs portray lethargic behavior, anorexia, and emesis symptoms. Besides, even small amounts of grapes or raisins could cause acute kidney failure in your dogs. Therefore, it is ideal to ensure your dog stays away from them.
3. Onions
All onions, whether raw, cooked, or powdered; have compounds that can become toxic to a canine’s red blood cells. When ingested, onions cause anemia that is manifested by weakness, vomiting, and difficulties in breathing.
4. Garlic
Garlic is another poisonous food that can cause stomach upset and reduce red blood cell levels in your dog’s body. It can take days for a problem of any sort to be evident. Some possible symptoms associated with garlic include weakness, vomiting, and the gums turning pale.
5. Avocados
While they may appear good, avocados contain persin, a toxin that can cause a dog to have diarrhea and vomiting, eventually causing fluid accumulation around the heart. Pet owners must prevent any access to avocados by their pets because some dogs tolerate them such as Chihuahuas while others like Bull Terriers do not.
6. Xylitol (Artificial Sweetener)
Artificial sweeteners are toxic to your dog. Pastries, candies, and sugar-free gums predominantly have xylitol which causes harm to dogs. So, once the dog eats any food item containing these substances, insulin is released quickly leading to hypoglycemia or low blood sugar. Consequently, they will experience seizures, and liver failure and may eventually die.
7. Macadamia Nuts
Additionally, macadamia nuts are yet another food that is poisonous for dogs. The toxicity from macadamia nuts can manifest through weakness, tremors, and vomiting heating. The slightest amounts of this food can make a dog very sick fast.
8. Alcohol
Dogs manifest greater sensitivity to alcohol influence than human beings. Ingesting alcohol can kill immediately or make dogs lose consciousness. Other symptoms included vomiting, difficulty breathing, and poor coordination.
9. Coffee and Caffeine
Coffee, tea, and other beverages containing caffeine are also poisonous to dogs. They contain Methylxanthines that cause vomiting, diarrhea, seizures, and rapid heartbeat, among other effects when consumed by your dog.
10. Raw Dough
You should be wary of raw dough especially one with yeast. Raw Dough made by the use of yeast can ferment in the dog’s stomach when consumed. When fermented, yeast causes the stomach to protrude abruptly therefore causing adverse health effects such as rupture in the digestive tract. The process of fermentation produces ethanol leading to alcoholism.
11. Cooked Bones
While raw bones are less harmful under certain conditions, cooked ones are fragile and therefore can splinter; thus dogs’ intestines may obstruct or tear apart.
12. Cherries
The amount of cyanide that cherries contain is not bearable for dogs. Ingesting cherries can cause red gums, affect breathing, and even death in severe situations.
13. Raw Meat or Fish (Salmon Poisoning)
When you feed your dog raw meat or seafood, you expose them to hazardous pathogens such as salmonella and E. coli. Besides, there is also a possibility of salmon served uncooked being infested with a parasite that is responsible for fatal salmon poisoning.
14. Raw Eggs
Raw eggs may appear safe for your dogs but they contain a significant number of salmonella bacteria that are, in fact, one of the familiar causes of food poisoning in dogs. An egg’s white element known as avidin reduces the body’s absorption rate of biotin leading to skin and coat problems.
15. Salt
Furthermore, large consumption of salt is poisonous to your dog. When dogs ingest large amounts of sodium ions from excessive salting, they can experience vomiting, diarrhea, trembling, and convulsions followed by death.
16. Nutmeg
Nutmeg contains myristicin, a harmful product that causes dangerous effects to your dog such as seizure attacks, increased heartbeat rate as well and hallucinations among many others within the canine species.
17. Milk and Dairy Products
As most dogs cannot digest lactose well enough it can make their tummy hurt causing bloating along with diarrhea.
18. Corn on Cob
The dog cannot be poisoned with corn grains but the cob can block intestines leading to surgical removal.
19. Mushrooms
Although not all, some types of mushrooms are poisonous to dogs as they lead to liver failure, vomiting, diarrhea, and seizures. When considering feeding your dogs some mushrooms, consult your veterinarian on the best type, one that will not cause any harm to them.
20. Fat Trimmings
Vets recommend one not feed their dogs foods that contain high levels of fat such as ham, bacon, or fat part as they result in pancreatitis. In addition, they may experience obesity and many other problems.
