We all love spoiling our dogs with little treats from our plates, but did you know that some of the most common foods we eat can be deadly for our furry friends? It’s a hard truth, but many pet owners are unaware that even the smallest amount of certain foods can cause serious health problems—or even death.
Sharing food with your dog might seem like a harmless gesture, but some human foods are toxic to dogs, and they don’t always know where to stop. In this article, we’ll discuss 22 common foods that can be deadly to your dog if consumed in large quantities. By the end of this post, you’ll know exactly what to avoid and how to protect your dog from these hidden hazards.
1. Avocados
Avocados contain persin, a toxin that is harmless to humans but can cause fluid buildup in a dog's lungs, leading to difficulty breathing. Even the pit can be dangerous, as dogs may chew on it, leading to choking or poisoning. Always make sure avocados are kept out of your dog’s reach.
2. Garlic
Garlic contains thiosulfate, a compound toxic to dogs. It can damage red blood cells, leading to anemia. Even small amounts of garlic can cause harm, so be cautious when cooking meals with garlic or sharing food containing it with your dog.
3. Macadamia Nuts
These nutrient-rich nuts might be great for us, but for dogs, they can cause severe issues. Eating macadamia nuts can result in nausea, diarrhea, weakness, and even temporary paralysis. Make sure macadamia nuts are kept well out of your dog’s reach.
4. Chocolate
Chocolate contains theobromine, which dogs cannot metabolize effectively. Even small amounts can lead to vomiting, diarrhea, seizures, and in extreme cases, death. Always keep chocolate—especially around holidays—out of your dog’s reach.
5. Xylitol
Xylitol, a sugar alcohol found in sugar-free gum, baked goods, and even toothpaste, is extremely toxic to dogs. It causes a rapid drop in blood sugar, leading to seizures, liver damage, and even death. Be sure to keep products containing xylitol out of your dog’s sight and reach.
6. Raw Yeast Dough
Raw dough can ferment in your dog’s stomach, causing painful bloating and alcohol poisoning. The fermentation process produces ethanol, which can lead to dangerous side effects. Always store dough securely and away from your dog.
7. Cooked Bones
While dogs love bones, cooked bones can splinter, causing serious damage to their digestive tract. They can puncture the stomach or intestines, leading to internal injuries. Instead, offer your dog raw bones or pet-safe chews.
8. Raisins and Grapes
Even small amounts of grapes or raisins can lead to kidney failure in dogs. Symptoms include excessive thirst, little to no urination, and lethargy. Never share grapes, raisins, or baked goods containing them with your dog.
9. Caffeine
Caffeine—found in coffee, tea, sodas, and even some energy drinks—can be fatal for dogs. It causes rapid heart rate, vomiting, restlessness, and, in extreme cases, death. Keep all caffeinated drinks safely out of your dog’s reach.
10. Rhubarb
Rhubarb contains oxalic acid, which can cause kidney failure in dogs. Symptoms of poisoning include drooling, diarrhea, vomiting, and tremors. Avoid giving your dog any food or treats containing rhubarb.
11. Onions and Leeks
Like garlic, onions and leeks contain compounds that damage red blood cells and can cause severe anemia in dogs. The effects may not show immediately, but they can take several days to manifest. Be mindful of sharing meals with onion or leek ingredients.
12. Alcohol
Even small amounts of alcohol—found in mouthwash, cleaning products, or alcohol-based cosmetics—can be deadly for dogs. Alcohol poisoning causes vomiting, poor breathing, and loss of coordination. Keep alcoholic beverages and related products away from your pet.
13. Salt
Excessive salt intake can cause salt poisoning in dogs, leading to symptoms like vomiting, diarrhea, tremors, and even seizures. Avoid sharing salty snacks like chips or pretzels with your dog, and ensure that food like this is out of their reach.
14. Citrus Oils
Essential oils containing citrus or citrus-based cleaning products can cause liver failure in dogs. Keep any citrus oils, such as lemon or orange-based, away from your dog’s reach, and don’t use them on their skin.
15. Dairy Products
Many dogs are lactose intolerant, and consuming dairy products can cause stomach upset, diarrhea, and vomiting. Although a small amount of cheese may not harm your dog, it’s best to avoid dairy entirely and stick to dog-safe treats.
16. Cat Food
While not immediately harmful, cat food is designed for cats and can upset your dog’s stomach. Long-term consumption of cat food, which is higher in protein and fat, can lead to digestive issues, sickness, and diarrhea.
17. Bacon
Bacon is high in fat and salt, both of which can cause pancreatitis in dogs. This painful condition requires serious veterinary care. Avoid sharing fatty meats like bacon, ham, or sausages with your dog.
18. Tobacco
Nicotine poisoning is common in dogs that accidentally ingest tobacco products like cigarettes, cigars, or nicotine patches. Symptoms include vomiting, diarrhea, tremors, and even paralysis. Always store tobacco products securely and away from your dog.
19. Nutmeg
Nutmeg contains myristicin, a compound that can cause seizures, hallucinations, and potentially fatal symptoms in dogs. While baked goods may not be as risky, always keep nutmeg containers sealed and out of your dog’s reach.
20. Peaches
While the peach flesh is fine for dogs, the pit contains cyanide, which can cause poisoning if ingested. Always dispose of peach pits immediately and keep them out of your dog’s reach.
21. Mustard
Mustard seeds and mustard itself can cause significant stomach upset in dogs, including vomiting and abdominal pain. Avoid feeding your dog mustard or any foods that contain mustard as an ingredient.
22. Fat Trimmings
Raw fat from meat can cause pancreatitis, a painful inflammation of the pancreas, in dogs. It can also lead to vomiting, diarrhea, and long-term health issues. Don’t let your dog eat fat trimmings or fatty leftovers.
