It is important for dog owners and dog lovers to remember that a dog’s digestive system is not the same as ours, so there are some foods that are perfectly safe for you to eat, but you should not feed your dog. In alphabetical order, some of the most common culprits include:
Alcohol: Giving you dog alcohol is dangerous and can cause coma and death.
Avocado. The persin in it is toxic to dogs, which can lead to vomiting and diarrhea, neither of which is fun for you or your canine companion!
Bread Dough: Cooked bread is safe for dogs, but if ingested uncooked, the yeast in bread dough can continue to expand in their stomach causing bloating or more dangerous consequences. The ethanol produced can also cause alcohol poisoning in dogs.
Cherries: The danger of cherries lies in the pits, which contain cyanide. Especially in smaller dogs, cherry pits can also be a choking hazard or can become a dangerous block to their intestines.
Chocolate: Chocolate contains caffeine, which is extremely dangerous to dogs, so never let your pooch have a bit of your favourite treat, and be sure to keep coffee and other sources of caffeine away from them, too. If ingested, caffeinated products (or more precisely, the methylxanthine chemical in them) can cause abnormal heart rates, seizures, vomiting, and even death in dogs. Note that chocolate treats made specifically for dogs actually contain a chocolate substitute so they are safe to give to your dog.
Citrus: Large amounts of citrus acid can cause stomach problems or even nervous system failure in dogs. What constitutes a “large” amount depends on the dog, so it’s best to avoid citrus all together whenever possible.
Cinnamon: Like citrus, large amounts of cinnamon can cause vomiting, diarrhea, and liver disease in dogs (although it’s not technically classified as a “toxic” food).
Coconut: Small amounts of coconut fruit or oil are ok for some dogs, but you should never give your dog coconut water as it contains too much potassium to be safe.
Ice Cream: The high levels of sugar in ice cream make it not a healthy food for dogs to eat. Remember, too, that just like humans, some dogs can be lactose intolerant!
Nuts: All nuts are a choking hazard, so never give them to your dog. Also, Macadamia nuts are, to dogs, a poisonous food that causes muscle weakness, vomiting, lethargy, and hypothermia.
Onions (and garlic, and chives): This family of Allium foods contain organosulfoxides that causes anemia, vomiting, diarrhea, and stomach pain in dogs.
Raisins: Do not feed your dog raisins, grapes, currants, sultanas, and other human foods that are made or processed with them as they are highly toxic to dogs, even in small amounts, causing kidney failure and even death.
Raw Eggs: Raw eggs in a dog’s diet can cause a biotin deficiency which can affect their skin and coat health.
Salt: Just like in people, salt increases thirst, which can potentially lead to dehydration. Salty food in a dog’s diet can also cause sodium ion poisoning, resulting in vomiting, diarrhea, shaking and tremors, fever, and seizures.
Xylitol: A sugar substitute in many human foods, Xylitol can cause liver failure and low blood sugar levels in dogs.
This list is not exhaustive and there are many considerations to a dog’s diet, especially if they have underling medical issues. Always consult with a dog nutritionist or your vet about a safe diet to feed your particular dog.
