Don’t Feed Your Dog These Foods!


When you’re having dinner or a quick snack and your faithful canine companion stares back at you with those sweet, “please feed me” eyes, it’s not easy to resist the temptation. But, beware there’s a lot of “people food” your dog should never eat. Some foods are very harmful to their health, so think again before you feed them.

From my own personal experience, my dog made a scary trip to the vet clinic after eating a few grapes.  With some treatment and care, there were no ill effects from this unfortunate event. The experience was a catalyst to learning more about the foods to avoid feeding my furry friend. I’m sharing the list with you, so you can avoid any issues with your beloved pet. The source for this list comes from a combination of the ASPCA and PetsWebMD.

I’ve listed the foods below in categories, but you can also get a one-page infographic that you can print out and put on your fridge. Just follow this blog and I’ll send you the document.


Apple seeds and cores
– the seeds and cores can cause dilated pupils, red mucous membranes, difficulty breathing, shock, and even death for your furry friend.

Apricot stems, leaves, and pits – much like cherries, this fruit contains cyanide which is poisonous. Warning signs include dilated pupils, bright red mucous membranes or difficulty breathing.

Avocado – the healthy fats in this fruit offer great benefits for us. But for dogs, the plant, its leaves, seed, bark and fruit can cause vomiting or diarrhea. Also, if eaten the avocado seed can get stuck in the intestines or stomach, causing an obstruction leading to death. So keep your dog away!

Cherry steams, leaves, and pits – these parts of the cherry have cyanide which is poisonous for your dog. Consumption can cause dilated pupils, red mucous membranes, labored breathing, shock, and even death.

Coconut and coconut oil – in large quantities can cause an upset stomach and diarrhea for your four legged one.

Grapes/Raisins– this is the one that I mentioned earlier….ugh! Grapes and raisins may be great snacks for your lunch, but they can cause kidney failure in your dog. Keep them in a sealed container – they can easily roll onto the floor where your dog will pounce on then. An early sign of consumption is vomiting on a constant basis.

Persimmons, Peaches, and Plums – the culprits are the seeds and pits in these fruits. They can block your dog’s intestines – leading to issues with eating and going #2. Peach and plum pits also have cyanide – which is toxic for any living creature.


Cinnamon – its oils can irritate the inside of your dogs’ mouth. It can lower your loyal companion’s blood sugar and lead to diarrhea, vomiting, increased, or decreased heart rate, and even liver disease. Inhaled the powder can cause difficulty breathing, coughing, and choking for your pet.

Hops – include compounds that can cause a malignant hyperthermia, which results in a rapid rise of body temperature, potentially resulting in permanent damage to the organs and brain or even death. Additional symptoms include redness around the mouth, excessive panting, excitement, abdominal pain, seizures, and rapid heart rate.

Mustard Seeds – these seeds are used to spice up foods and for certain types of medicine. However, in dogs the effect is more painful causing vomiting and diarrhea.

Salt – chips, pretzels and popcorn are a yummy treat for us humans, but the salt content can cause havoc for our furry friends. From too many pee stops to potential ion poisoning. Clear signals include diarrhea, vomiting, fever, tremors and seizures and in the worst case – death.

Sugar – it tastes great, but just like with humans, too much of it can cause dental issues and obesity for your pet.


Corn on the cob – avoid giving your dog a full corn on the cob. Dogs can try to eat the entire cob causing them to choke and have an intestinal blockage. This could be fatal to your canine companion.

Garlic – this lovely food doesn’t just cause trouble for Dracula. Garlic can poison your dog and cause weakness, vomiting, and breathing problems.

Onions– these human staples can kill red blood cells in your dog, causing anemia. Eating a good portion of onions and garlic can poison your dog and cause weakness, vomiting, and breathing problems.

Potato leaves, stems, skin, or any green parts – potato plants have a toxic substance named Solamine that can be harmful for your dog. The toxin can cause vomiting, diarrhea, anorexia, disorientation, lethargy, and central nervous system issues.


Chamomile – this plant herb is consumed as a natural remedy for several health conditions. But it has a harmful effect for dogs potentially causing dermatitis, vomiting, diarrhea, and anorexia.

Citrus – these plants contain citric acid and essential oils that in large quantities can cause irritation and even central nervous system issues. In small amounts there probably won’t be any issues beyond an upset stomach.

Rhubarb – the leaves from the Rhubarb plant (cooked or raw) contain toxins that are poisonous. Consumption by your canine companion could cause hyper salivation, tremors, and kidney failure.

Tomato Plant – these plants have toxic elements that can be harmful for dogs. The side effects include nervous system issues to digestive ailments. It’s best to err on the side of caution and keep your pets away from your tomato plants.


Chocolate – we would all love to share the joy of chocolate, but don’t. All chocolate is harmful, dark, milk even white. The most toxic is dark chocolate and unsweetened baking chocolate. The sugary treat can cause your four legged one to throw-up, experience diarrhea, heart issues, seizures and potentially death.

Licorice – this candy can be a cause of joy for us humans. Licorice contains glycyrrhizic acid which can cause complications for our furry friends when consumed in large quantities. It can cause complications muscle damage and adrenal gland issues.

Xylitol – is a sweetener that is used as a sugar substitute in a range of foods like candy, gum, deserts and diet foods. The substance can drop your dog’s blood sugar, trigger seizures and in just a few days cause liver failure. Early symptoms include vomiting, lethargy, and coordination problems.

Yeast Dough – can stretch your dog’s stomach and cause a world of hurt. Also, as the yeast ferments the dough to make it rise, it creates alcohol that can lead to alcohol poisoning for your best friend.


Macadamia Nuts – keep these tasty treats away from your furry friend. Just a few raw or roasted macadamia nuts can make your dog ill. Look for symptoms like vomiting, fever, muscle shakes, and weakness in the hind legs.

Nuts – stay clear of almonds, pecans, and walnuts. They contain high amounts of oils and fats. The fats can cause vomiting and diarrhea, and potentially pancreatitis in pets.


Alcohol – this one may seem obvious, but alcohol is bad not only for you, but your dog too. Because your dog is smaller it takes a lot less to harm your canine companion. Just a little bit can have a negative impact including vomiting, diarrhea, breathing issues, coma, and potentially death.

Coffee, Tea, and Other Caffeine – Caffeine may keep you up, but it can put your dog permanently to sleep. Keep your dog away from sodas, energy drinks, coffee, tea and anything else that contains the deadly substance. Always check labels for caffeine – better safe than sorry!

Milk and Other Dairy Products – some of us are lactose intolerant, so you may know the feeling that your pouch could experience. Ice cream, milk and other dairy products can cause diarrhea and other digestive problems for your pup. I found this out the hard way when I had to clean the floor after a serving of ice cream.


Marijuana and edibles – with the drug becoming legal in more places, there is a great chance of exposure for dogs. Keep your pets away from the substance. It can cause a range of harmful effects such as lethargy, hypothermia, excessively low or high heart rates, low blood pressure, vomiting, diarrhea, incontinence, coma, or  even death in the worst case scenario.

Medicine – can be pain relievers for us, but can create pain for our four legged friends. The ingredients such as acetaminophen or ibuprofen common in pain relievers and cold medicine can be fatal to your pet. So don’t play doctor with your pet, always go to a vet for medication.


Cat Food – contains proteins and fats that are targeted specifically for cats. The protein and fat levels in cat food are too high for your dog, and not healthy. Ingesting too much cat food can result in upset stomach, obesity and pancreatitis.

Fat Trimmings and Bones – this seem like something your dog should be able to eat, but fat trimmed from meat can cause pancreatitis in dogs. Bones can also clog and create cuts in your faithful companion’s digestive system.

Raw Eggs – much like in humans, this food source can cause poisoning from bacteria like salmonella or E. coli for your canine. If you’ve ever had food poisoning, you know it’s a bad time.

Raw Meat and Fish – without cooking raw food, bacteria can live on and cause food poisoning. Early warning signs include throwing-up, a high temperature, and swollen lymph nodes.

So what happens, if you think your dog has eaten a toxic food? Don’t take a chance, call your local vet, a nearby emergency clinic or the ASPCA Animal Poison Control Center at (888) 426-4435 for help.
