Foods Harmful to Dogs

As a fervent dog enthusiast and advisor, I feel it’s essential to raise awareness about the foods that are harmful to our canine friends. This article’s aim is to provide you, fellow dog owners, with useful information to protect your fur buddies from potential health risks.

The Role of Dog Owners As a responsible dog owner, it’s our duty to understand what our dogs can and can’t eat. Not all foods that are safe for us are safe for our dogs. Let’s dive into the list of foods harmful to dogs.

Common Foods Harmful to Dogs

Let’s start with the most common culprits:


Believe it or not, our beloved sweet treat is a no-go for dogs. The theobromine in chocolate can cause severe symptoms in dogs, including restlessness, rapid breathing, and in severe cases, seizures.

Cocoa Powder: While not a spice per se, it’s worth mentioning because it’s often used in a similar way in cooking and baking. Cocoa powder, like chocolate, contains theobromine and caffeine, which can be harmful or fatal to dogs.

Grapes and Raisins

This seemingly harmless fruit can cause acute kidney failure in dogs. Even a small amount can have devastating effects.

Onions and Garlic

They can cause a condition called hemolytic anemia, leading to damage to the red blood cells. This can cause your dog to become weak and lethargic. Both of these common cooking ingredients can be toxic to dogs. They belong to the Allium family, which also includes leeks, chives, and shallots. These ingredients also can cause damage to a dog’s red blood cells, leading to a condition called hemolytic anemia, which can cause weakness, shortness of breath, and lethargy in dogs.


Nutmeg contains a compound called myristicin, which can cause severe stomach upset in dogs. In larger quantities, it can lead to rapid heart rate, hallucinations, and seizures.


 Again, while not a spice, too much salt can be harmful to dogs. High levels of sodium can lead to salt poisoning, which can result in vomiting, diarrhea, seizures, and in severe cases, death.


 While not typically fatal, too much cinnamon can cause vomiting, diarrhea, and heart complications in dogs. The oil in particular can irritate a dog’s mouth and lead to discomfort.

*As a general rule, it’s best to avoid giving your dog human foods that have been seasoned with these or any spices. If you think your dog has ingested a harmful amount of any spice or food, it’s important to contact your veterinarian right away.

Also Avoid:


Just as it affects humans, alcohol can have harmful effects on dogs, but much worse. It can cause vomiting, diarrhea, difficulty breathing, and even death.


Caffeine is extremely harmful and potentially fatal for dogs. It can lead to restlessness, rapid breathing, heart palpitations, muscle tremors, and seizures.

Other Less Known Harmful Foods

Here are some foods that might surprise you:


Avocado contains a substance called persin, which can cause diarrhea, vomiting, and heart congestion in dogs.

Dairy Products

Dogs lack the enzyme to break down lactose in dairy products, which can lead to digestive problems.


Xylitol is a sweetener found in many products, including some peanut butters. It can cause insulin release, which leads to liver failure in dogs.


The Importance of a Balanced Diet

Why should we care about what our dogs eat? The answer is simple: their well-being. A balanced diet ensures our dogs receive the necessary nutrients to grow, stay active, and maintain a healthy immune system.

A balanced diet plays a vital role in your dog’s overall health and well-being, just as it does for us humans. The proper nutrients in the right proportions are crucial for their development, overall health, and longevity.

Firstly, it’s essential to realize that dogs are omnivores, which means they need a balanced blend of proteins, carbohydrates, fats, vitamins, and minerals to function optimally.

Protein is a critical part of a dog’s diet as it aids muscle growth and repair, skin and hair regeneration, immune response, and hormone production. Dogs can obtain protein from various sources, including meat, poultry, fish, and some plant-based sources.

Carbohydrates, though not a compulsory part of a dog’s diet, can provide them with quick and accessible energy. These can be found in vegetables, fruits, and grains.

Fats are a concentrated energy source and are required for absorbing certain vitamins. They also contribute to a healthy skin and coat. Sources of good fats include fish, flaxseed, and olive oil.

Vitamins and minerals are necessary for countless bodily functions. They aid bone growth, support the immune system, and help wound healing, to name a few.

When it comes to a balanced diet for dogs, one size doesn’t fit all. Nutritional requirements can vary based on a dog’s age, breed, size, activity level, and overall health. Puppies, for example, require more protein for their growing bodies, while senior dogs might need a diet with fewer calories but rich in certain nutrients.

Providing a balanced diet to your dog also reduces their risk of obesity and related health problems, such as diabetes, heart disease, and arthritis.

Finally, it’s important to note that while a balanced diet is crucial, it’s equally important to provide safe foods. As we’ve discussed earlier, certain human foods can be harmful or even fatal to dogs. Always make sure the foods you give are dog-friendly and in the right proportions. And remember, when in doubt, it’s best to consult your vet.



In conclusion, it’s crucial for us, as dog owners, to understand the foods harmful in which dogs should avoid. When in doubt, consult your veterinarian.
