Foods that are poisonous to dogs
5 min readIt can be tempting to give our dogs leftovers or share our food with them, but it’s important to remember that certain foods that are safe for humans can be harmful to canines. Dogs have a different metabolism, so feeding them human foods can be extremely dangerous, and even poisonous.
To avoid any risks, click through the following gallery to discover foods that are poisonous to dogs.
Avocados
Avocados are dangerous, partly due to a fungicidal toxin called persin. Only high doses are lethal, but mild symptoms like vomiting and diarrhea can occur from consuming smaller portions.
Apples
The flesh of apples is not toxic, but the seeds can be poisonous due to a compound called amygdalin. However, they have to be consumed in large quantities and chewed to be toxic.
Garlic
Garlic can be fatal to dogs due to a compound called thiosulfate that damages red blood cells. It takes a lot of garlic to cause toxicity, but some breeds are particularly sensitive.
Milk and other dairy products
Even though milk and dairy products have calcium-boosting properties, they can be bad for dogs and contribute to levels of lactose intolerance. This can cause a lot of discomfort for canines.
Macadamia nuts
In general, nuts are not good for dogs, especially macadamia nuts. These are ranked as the most toxic, which can lead to vomiting, weakness, hyperthermia, and loss of bodily functions.
Mustard
Mustard won’t be lethal to dogs in small doses, however, it can be toxic in higher amounts. In fact, due to mustard’s mild toxicity, it’s often something that’s suggested by vets as a way to induce vomiting when needed.
Artificial sweetener (xylitol)
Xylitol is a sugar alternative found in human foods such as candy and many baked sweets. It’s extremely toxic to dogs, causing rapid insulin release that can put them in a coma within 15 to 20 minutes.
Chocolate
Chocolate contains a stimulant called theobromine, which is poisonous to dogs. The amount of theobromine depends on the type of chocolate. It mainly affects the gut, heart, central nervous system, and kidneys.
Onions
Onions can be poisonous to dogs due to the thiosulfate they contain. Certain dog breeds are more vulnerable, and their size makes a huge difference.
Cooked bones
Giving your dog a raw, uncooked bone to chew on is great, but avoid cooked bones. These can easily splinter and in large quantities cause constipation or perforation, which can be fatal.
Grapes and raisins
Grapes and raisins rank among the most serious food threats for dogs. Small amounts can even cause sudden kidney failure, and commonly cause vomiting and diarrhea.
Caffeine
A small amount of caffeine won’t do any harm, but if your dog swallows a handful of coffee beans or tea bags then it can pose serious danger.
Yeast
If your dog eats unbaked dough, it can be extremely dangerous because the fermenting yeast gets quickly absorbed in the bloodstream, where it produces enough ethanol to cause alcohol poisoning.
Rhubarb
Rhubarb can cause kidney failure in dogs due to an antinutrient called oxalic acid. The substance creates crystals in the urinary tract and can cause the kidneys to shut down.
Nutmeg
Nutmeg contains a compound called myristicin, which, when ingested by dogs in large quantities, can lead to rapid heart rate, hallucinations, and seizures.
Currants
Even though true currants are not toxic, most sold in the United States, called Zante currants, are tiny raisins made from Corinth grapes. These cause the same toxicity as regular grapes and raisins.
Iron vitamins
Vitamins containing iron can be toxic for dogs, as they can damage their digestive system wall lining, kidneys, and liver. Prenatal supplements are particularly dangerous, as they tend to have higher amounts of iron than standard vitamins.
Wild mushrooms
Grocery store mushrooms are typically safe for dogs, but wild mushrooms can be toxic. If you catch your dog trying to eat them in the wilderness, stop them immediately.
Citrus oil
It’s typically fine for dogs to eat oranges, but citrus oil, often used medicinally, is not okay. This is because of the insecticidal properties of the oil that can lead to liver failure in dogs.
Peaches
The peach flesh itself is fine for dogs to eat, but the pits of peaches contain amygdalin, the same substance found in apple seeds, which is toxic for your pup.
Leeks
Leeks contain thiosulfate, the same compound that makes onions and garlic unsafe for dogs. These food types are all part of the allium family.
Cat food
Cat food won’t poison your dog immediately, but it can lead to pancreatitis and other health complications over time, causing organ damage and even death.
Black walnuts
Regular walnuts are safe for dogs to eat, but the less common black walnut can be toxic. These are mainly used in desserts and baked goods, but dogs can find them out in nature.
Spinach
Spinach contains a high amount of oxalic acid, a substance known to interfere with dogs’ ability to absorb calcium. This can cause kidney damage if consumed regularly.
Chives
Like garlic, leeks, and onions, chives can be poisonous to dogs in large amounts. Toxic doses of chives can cause damage to the red blood cells and lead to anemia.
Tobacco
Tobacco isn’t technically a food, but it’s something ingested by humans, which can be extremely lethal for dogs if they manage to chew on cigarettes.
Green tomatoes
Once tomatoes are ripe, then they’re safe for dogs. But green tomatoes or not fully ripe red tomatoes can be toxic for dogs due to a substance called solanine.
Cherries
Similarly to peaches, cherries contain amygdalin in their pits, which is toxic to dogs. In addition to the toxic pits, cherry flesh can make their stomach upset.
Potatoes
Potatoes are toxic for dogs due to them containing solanine. It blocks a chemical called acetylcholine, which dogs need to transmit nerve impulses. And this can result in issues with the nervous system and intestinal tracts.
