Types of Food that are Poisonous to Dogs

Most dogs would eat anything. From your leftovers to the food you still intend on eating and to their own pet food. However, pet owners and dog lovers should be aware that not all foods are safe for man’s best friend. Some food can be quite toxic to dogs. Below are types of food that are poisonous to dogs:
Alcoholic Beverages. Alcohol can cause intoxication in humans. It can very much cause intoxication in dogs as well. Alcoholic beverages can even cause coma and death.
Avocado. Everything about avocado (the fruit, the leaves, the stem, and the pit) is all considered toxic for dogs. Avocado has Persin, a fatty acid derivative, which is toxic for dogs. This can cause diarrhea, vomiting, generalized congestion, difficulty in breathing, fluid accumulation around the heart, and heart failure in dogs. The amount of avocado needed to poison a dog is currently still unknown.
Bones. Bones of fish and other meat can obstruct the digestive system. They may also cause lacerations in the digestive tract.
Broccoli. Broccoli can cause intestinal irritation when fed in very large quantities (more than 10 % of the dog’s diet).
Candies with Xylitol. Candies with this sweetener can cause liver problems and even death.
Chocolates. Chocolates have theobromine. Theobromine stimulates the heart and the nervous system. Dogs are more sensitive compared to humans and so this substance can cause seizures, coma, and death due to heart failure. This substance stays in the dog’s system for a long time. So feeding your dog repeatedly with small amounts of chocolate can still be harmful. There is, however, dog chocolate wherein the theobromine has been removed.
Coffee and Other Caffeinated Foods and Beverages. Caffeine has similar effects on dogs as theobromine. Caffeine increases the respiratory and heart rates of dogs. It causes restlessness and affects the central nervous system of dogs.
Citrus Oil Extracts. These oil extracts can lead to vomiting and must be avoided.
Grapes and Raisins. Grapes and raisins have an unknown substance that is toxic for dogs. It can cause kidney failure, diarrhea, vomiting, lethargy, loss of appetite, and abdominal pain. Raisins are more concentrated compared to grapes. Thus, they are more toxic.
Hops. Hops are highly toxic for dogs. They cause malignant hyperthermia in dogs and usually result to death. The elevated temperature leads to excessive panting, increased heart rate, and seizure. Greyhounds are more sensitive to hops compared to other breeds.
Liver. Large amounts of cooked liver can cause vitamin A toxicity. This affects the muscles and bones of the dogs.
Macadamia Nuts. Macadamia nuts, both raw and roasted, can cause tremors in dogs. Just like grapes and raising, these nuts have unknown toxins that can cause vomiting, lethargy, abdominal pain, hyperthermia, stiff joints, and lameness.
Mushrooms. These fungi can result in shock and even death. However, different types of mushrooms have different effects on dogs. They can cause diarrhea, nausea, vomiting, depression, abdominal pain, hallucinations, liver failure, drooling, seizures, tearing, kidney failure, heart damage, and hyperactivity.
Mustard Seeds. This type of seed has varied effects on dogs.
Nutmeg. High amounts of nutmeg can lead to tremors, seizures, central nervous system problems, and death.
Onion. Everything (raw, cooked, powder, and shallots) onion and has onion is toxic for dogs. Onions have thiosulphate that causes the destruction of red blood cells, resulting to hemolytic anemia and potentially life-threatening anemia. Continuous exposure to small amounts of onion can be a serious threat. Garlic has the same effects but require larger amounts to be considered toxic.
Potato Leaves and Stems. These potato parts are dangerous for dogs as these can cause digestive, urinary, and nervous system problems.
Rhubarb Leaves. Rhubarb leaves have similar effects with potato leaves and stems. Large amounts of these leaves, whether cooked or raw, can cause convulsions, coma, and death.
Salt. Just like in humans, excessive amounts of salt can cause kidney failure and electrolyte imbalance.
Seeds/Pits of Apple, Apricots, Cherries, Peaches, and Plums. These fruits themselves are not considered as toxic. However, their seeds/pits are. The seeds/pits of these fruits contain a type of cyanide compound and if enough of it is eaten, it could poison your dog.
Tomatoes. Tomatoes have atropine. Atropine causes the pupils to dilate. It also causes tremors and heart arrhythmias. The highest concentration of atropine is found in the leaves and stems of the plant.
Walnuts. Walnuts can cause gastrointestinal problems and respiratory issues. Walnuts can make your dog suffer vomiting, diarrhea, sneezing, coughing, and difficulty in breathing.
Yeast/Bread Dough. This can expand and produce gas. It can result in pain and possible rupture of the stomach and intestines. Rising dough also releases ethanol. This can lead to alcohol poisoning.

All of the above food can be harmful for dogs. As much as possible, avoid feeding your pets with these foods. Or at least limit the amount that your give your dogs.
