10 Foods That Are Bad for Dogs

We’ve all been tempted to give our dog people food when they give us their best “puppy dog eyes.” Those large, hopeful eyes and a sheepish little smile are enough to make anyone’s heart melt. There are many food items that humans consume, that can be extremely harmful for your four-legged friend. Here are the top ten foods to avoid feeding your dog.

Grapes & Raisins

This is a surprising one. Only a few may cause your dog to become extremely sick and can even ultimately result in kidney damage. Look for signs of constant vomiting, sluggishness, and depression. Researchers know there is a substance found in grapes and their condensed, dried counterpart, the raisin that is poison to your pup. Stay safe and keep grapes and raisins out of your dog’s reach.

Onions & Garlic

Many of us know not to let our dog eat onions and garlic. What is less commonly associated is that even onion and garlic powder can cause anemia, damaging red blood cells, in canines.  Signs of weakness, vomiting, and breathing problems are all symptoms that your dog may have ingested something listed here. This item on the “do not eat” list also includes all onion family members: green onions, leeks, shallots, even lilies and daffodils.

Sweets, Chocolate, Xylitol

Most people are aware that dogs shouldn’t eat chocolate but few understand why.  Theobromine is a chemical in caffeine, also present in chocolate and tea.  Theobromine is poisonous to both cats and dogs.  While there are different quantities of theobromine in milk, bitter, and white chocolates it is wise to just avoid chocolate all together when it comes to your pets.  How much theobromine your pet can metabolize without suffering serious consequences is based on pet weight and the concentration of theobromine contained in the tea or chocolate.  All sweets are terrible for your dog. Not only will it lead to weight gain, but may also cause their blood sugar to drop, induce vomiting, lethargy, and could even lead to liver problems.

Xylitol, most commonly found in chewing gum, is extremely dangerous for your dog. If there is any chance that your dog has consumed xylitol, take them to the veterinarian right away!


While we use caffeine as a pick-me-up most mornings, it can be extremely dangerous for your pup. Signs of restlessness, fast breathing, and muscle twitching are all signs that your dog may have consumed caffeine. Under this list, I also want to emphasize coffee beans, instant espresso powder, cocoa powder, sodas containing caffeine, and energy drinks.  None of these items have a place in your pooch’s diet.


Avocado contains a plant-derived substance called persin. Persin is toxic to many animals and can lead to heart damage and potential problems suckling offspring.  Persin is present in avocado leaves, branches, and the fruit that the tree produces.  So, although avocado toast is the new thing for a casual brunch, it’s best to keep Fido far away from our top food trend.


Alcohol has similar effects to dogs as to humans. The only problem is that Fido is much smaller than you! Alcohol is actually poisonous to animals, as it is to people.  People however, are able to metabolize it differently than cats or dogs so reaching a toxic consumption level takes a longer period of time of a gross excess consumption.  The amount required for toxicity in a pet is less than would br required by a human because the size of a person is often much greater than the size of a pet. Look for signs of vomiting, diarrhea, decreased coordination, difficulty breathing, and tremors.

Macadamia Nuts

Another popular health food, macadamia nuts are also poisonous to dogs.  Strangely enough, dogs are the only animal known to experience poisoning from macadamia nuts. Muscle trembling, vomiting, and weakness in hind legs are all indicators that your dog may have consumed macadamia nuts.

Milk and other Dairy

Ice cream is delicious. Unfortunately, dairy, ice cream, milk, and the like cause some major problems to the canine digestive system. Dogs may react by exhibiting signs of severe itching or allergies.  More severe reactions can be accompanied by diarrhea.  

Over-the-Counter Medications

Always consult with a veterinarian if your dog is sick. Never attempt to give your dog over-the-counter or prescription human medication. This can be extremely dangerous and cause irreparable consequences. Even seemingly harmless medicine like Tylenol can cause stomach ulcers in dogs. Save yourself a trip to the pet emergency room and have your dog diagnosed the right way, by the veterinarian.

What happens if Fido does get ahold of human food while you’re not watching? Don’t fret. Many human foods are not life-threatening, but may simply cause indigestion in your pup. To combat indigestion, always keep probiotics handy. This helps put good bacteria back into your dog’s gut lining. I recommend Probiotic Treats for Dogs Digestive Support! Dogs gobble these up. Looking for something cat-friendly? Particular Paws also has a Probiotic powder for dogs! Probiotics are a great way to make sure that your pet’s digestive system can handle anything your pet may find and ensure healthy digestive and intestinal function throughout all your pet’s life stages.
