Human Foods that Dogs Can’t Eat

#1: Avocados


Most people love guacamole; and given the chance, your dog would likely devour it as well. However, avocados are food that you shouldn’t be feeding your dog. A substance found in avocados called Persin can potentially be harmful to dogs in large quantities. It’s perfectly fine for human consumption, unless you have a particular allergy.

#2: Alcohol


This should be a no-brainer, but you’d be surprised by the number of people who think it’s funny to give their dog a drink! Alcohol has the same effect on a dogs brain and liver as it does on humans, but they’re much more sensitive to it. That means even a very small quantity of alcohol can make your dog extremely sick.

#3: Garlic & Onions


Garlic and onions – no matter whether they’re raw, cooked, part of a larger dish or in powder/flake form – can be harmful to your dog. They’re toxic to dogs because they do damage to their red blood cells, which can lead to anemia. Common signs of anemia in dogs are weakness, vomiting and lack of appetite.

#4: Grapes & Raisins


You may think that grapes and raisins are nice little treats for dogs, but the reality is that they can be extremely harmful. Vets aren’t 100% clear on why they’re so bad, but they do know that an excess amount of grapes and/or raisins can cause kidney failure in dogs.

#5: Coffee, Tea and Caffeine


Caffeine ingested by dogs in large quantities can be fatal and once they’ve been poisoned by it, often times there is no way to reverse course and save them. Common signs of a caffeine overdose in dogs include rapid breathing, muscle tremors and heart palpitations.

#6: Macadamia Nuts


Macadamia nuts or foods that contain traces of the nuts can be fatal to dogs. Researchers say that as few as 6 nuts can be enough to induce poisoning in dogs which is so acute that it can kill them. Symptoms of Macadamia nut poisoning include weakness, partial paralysis, muscle spasms, vomiting and rapid heart rate.

#7: Milk & Dairy Products


Like humans who have IBS or other digestive issues, dogs are very sensitive to dairy products. Although they’ll be begging for a lick from your ice cream cone on a hot summer’s day, you need to refrain from letting them have a taste. Dairy products can cause itching, diarrhea and a number of other digestive issues in dogs.

#8: Candy and Gum


Candy, gum and some baked foods are often sweetened with a substance called Xylitol (in addition to sugar). Xylitol is very harmful for dogs; it can cause they’re blood sugar to drop to dangerously low levels and also contribute to liver failure.

#9: Chocolate


Chocolate may the most common food NOT to feed your dog, as most dog owners and even non-dog owners alike have been trained to keep chocolate away from their dogs. Excess chocolate – especially dark chocolate and baking chocolate – can cause a dog to experience diarrhea, vomiting, seizures and can even be fatal in some cases.

#10: Fat and Bones from Meat


Most dog owners think it’s OK to treat their furry friends with fat trimmings and bones from whatever meat they had that night for dinner. However, both fat trimmings and bones are dangerous to dogs. The fat can lead to pancreatitis, while the bones can splinter and cause all sorts of damage to the digestive tract.

#11: Raw Eggs


Raw eggs have always been part of popular diet fads for bodybuilders and health nuts alike, but don’t even think about feeding them to your dog! For starters, they could get Salmonella or E. Coli poisoning. There is also an enzyme in raw eggs that interferes with a dogs ability to adequately absorb Vitamin B, which can lead to all sorts of skin and coat issues.

#12: Peaches & Plums


The pits of peaches and plums can be harmful to your dog in that they can get lodged in their intestines. Peach and plum pits also contain trace amounts of cyanide; humans avoid this by not eating the pits, but dogs don’t know any better.

#13: Salt


Although salt is a favorite flavoring of humans, you shoulnd’t be using it in any of your dog’s food or treats. Too much salt for a dog can cause excessive thirst and urination and potentially lead to sodium ion poisoning. Common symptoms of too much salt in dogs include depressions, vomiting and diarrhea.

#14: Raw Meat & Fish


Raw, uncooked meat and fish may contain all sorts of bacteria that can be harmful to your dogs. While you may think giving them raw meat or fish every once in a while is good because it’s what they would do in nature, think again. In particular, raw fish can contain parasites that are particularly harmful and in some cases fatal for dogs.

#15: Your Own Medication


You may be tempted to try and solve some of your dogs common health problems with your own OTC – or even prescription – medications. Although your medication may be perfectly safe for you, it likely hasn’t been tested for dogs and can caused different side effects or even be fatal in some cases.
