Are Dogs Allowed to Eat Pizza? Unveiling the Surprising Truth

No, dogs should not be fed pizza as it can be harmful to their health. Now let’s delve into why dogs should avoid consuming this popular human food choice.

While pizza is undoubtedly a delightful treat for many people, it contains ingredients that can be detrimental to a dog’s well-being. The crust often contains wheat, which some dogs are allergic to. Additionally, the toppings such as cheese, tomato sauce, and various spices can upset a dog’s stomach and potentially lead to gastrointestinal issues.

Moreover, certain pizza toppings like onions, garlic, and pepperoni are toxic to dogs and can cause severe health problems. Therefore, it is best to stick to a balanced diet specifically designed for dogs and avoid feeding them pizza altogether.

The Digestive System Of Dogs

Dogs have a unique digestive system that differs from that of humans. Understanding their digestive system is essential in determining whether dogs should be allowed to eat pizza. Dogs belong to the carnivorous group of animals, and their digestive system is designed to process protein-rich foods efficiently.

Their digestive system starts with the mouth, where the salivary glands produce enzymes that start the breakdown of carbohydrates. However, unlike humans, dogs have fewer salivary glands, resulting in minimal carbohydrate digestion in the mouth.

Once the food is chewed and swallowed, it travels down the esophagus and enters the stomach, which is responsible for further breakdown of food through the action of gastric acids and enzymes. Dogs have highly acidic stomachs, which allows them to break down and absorb nutrients from raw meat more effectively. This highly acidic environment is the reason why dogs are less susceptible to foodborne illnesses caused by bacteria like salmonella.

From the stomach, the partially digested food moves into the small intestine, where the majority of nutrient absorption takes place. The small intestine is lined with villi, finger-like projections that increase the surface area for nutrient absorption. These villi play a crucial role in extracting essential nutrients from the food and transferring them into the bloodstream for distribution throughout the dog’s body.

After the small intestine, the remaining waste moves into the large intestine, also known as the colon. The colon’s primary function is to absorb water and electrolytes, while also fermenting any remaining indigestible fibers. The waste material is then stored in the rectum before being eliminated from the body through the anus.

The digestive systems of humans and dogs differ in several key aspects:

  1. Diet: Humans have evolved as omnivores, capable of digesting both plant and animal matter. Dogs, on the other hand, are primarily carnivorous, with their digestive systems optimized for meat consumption.
  2. Stomach Acidity: While humans have a lower stomach acidity, dogs have highly acidic stomachs. This allows dogs to break down raw meat efficiently, while humans rely more on cooking to aid in digestion.
  3. Pancreatic Enzymes: Dogs have a shorter digestive tract than humans, with a larger stomach and comparatively shorter small intestine. This difference is complemented by the presence of additional pancreatic enzymes in dogs, which help break down proteins efficiently.

Overall, the unique digestive system of dogs showcases their natural inclination towards a meat-based diet. While small amounts of non-toxic and suitable human foods can be incorporated into a dog’s diet in moderation, it is important to be mindful of their digestive sensitivities when it comes to offering them indulgences like pizza.

Ingredients In Pizza Harmful To Dogs

When it comes to dogs, their dietary needs can be different from humans. While it’s tempting to share our delicious foods with our furry friends, it’s important to be cautious and informed about what is safe for them to eat. Pizza, a beloved comfort food for many, may not be the best choice for your four-legged companion. In this post, we’ll explore the various ingredients in pizza that can be harmful to dogs. From cheese to dough, we’ll break down the potential risks to help you make an informed decision when it comes to sharing pizza with your canine friend.


One of the key ingredients in pizza is cheese. While cheese may be a favorite treat for dogs, not all types of cheese are safe for them to consume. Some dogs are lactose intolerant, and consuming cheese can lead to digestive upset, including bloating, gas, and diarrhea. Additionally, cheese can be high in fat and calories, which can contribute to obesity and other health issues in dogs. It’s best to limit or avoid feeding pizza with cheese to your furry friend.

Garlic And Onion

Garlic and onion are commonly used seasonings in pizza sauce and toppings. While they can add flavor to the human palate, these ingredients can be toxic to dogs. Both garlic and onion can cause anemia in dogs by damaging their red blood cells. Symptoms of garlic and onion poisoning in dogs include weakness, vomiting, diarrhea, and pale gums. It’s crucial to keep pizza with these ingredients far away from your canine companion.

Tomato Sauce

Tomato sauce is another common ingredient used in pizza, but it can be harmful to dogs. Tomatoes belong to the nightshade family, and while ripe, fresh tomatoes are generally safe for dogs, tomato sauce often contains added sugars, salt, and other seasonings that can be problematic for canines. Excessive consumption of tomato sauce can upset a dog’s digestive system and may lead to gastrointestinal issues such as vomiting and diarrhea. It’s best to avoid sharing pizza topped with tomato sauce with your furry friend.


The dough used to make pizza can also pose a risk to dogs. Raw dough contains yeast, which can ferment in a dog’s stomach and cause alcohol poisoning. This can lead to symptoms such as disorientation, vomiting, bloating, and even seizures in severe cases. Moreover, the dough can expand in the stomach, causing discomfort and potentially leading to a dangerous condition known as gastric dilatation-volvulus. It’s essential to keep pizza dough out of reach of your curious canine companion.

Meat Toppings

Meat toppings like pepperoni, sausage, or bacon are common choices for pizza lovers. However, these fatty, greasy meats can be harmful to dogs. The high-fat content in meat toppings can lead to pancreatitis, a painful inflammation of the pancreas. Symptoms of pancreatitis in dogs include vomiting, diarrhea, abdominal pain, and loss of appetite. It’s best to avoid sharing pizza with meat toppings with your furry friend.

Processed Ingredients

Pizza often contains processed ingredients, such as artificial flavors, preservatives, and additives. These ingredients can be harmful to dogs, as their digestive systems are not designed to handle such chemicals. Consumption of processed ingredients can lead to digestive upset, allergies, and even long-term health issues in dogs. If you’re considering sharing a slice of pizza, it’s important to choose a dog-safe alternative free from processed ingredients.

Potential Risks And Health Issues

While many of us humans enjoy indulging in a cheesy, delicious pizza, it’s important to remember that not all foods that we enjoy are safe for our dogs to consume. Feeding your furry friend pizza may seem like a harmless treat, but there are potential risks and health issues that you should be aware of. Let’s take a closer look at some of these concerns:

Upset Stomach And Vomiting

Dogs have sensitive digestive systems, and indulging in pizza can upset their stomachs, leading to discomfort and potential vomiting. The high-fat content, spices, and seasonings commonly found in pizza can be too much for your dog’s digestive system to handle, resulting in an upset stomach.


In addition to an upset stomach, some dogs may experience diarrhea after consuming pizza. This can be caused by the combination of ingredients that are unfamiliar to their digestive system, leading to an imbalance and resulting in loose stools.


Pancreatitis is a potentially serious condition that can be triggered by the consumption of high-fat foods, such as pizza. This condition occurs when the pancreas becomes inflamed, leading to severe abdominal pain, vomiting, and diarrhea. If left untreated, pancreatitis can become life-threatening, so it’s crucial to avoid feeding your dog foods that are high in fat content, like pizza.

Toxicity From Certain Ingredients

Some ingredients commonly found in pizza can be toxic to dogs. For example, onions and garlic, which are often used as toppings or in pizza sauce, contain compounds that can cause damage to your dog’s red blood cells. Additionally, other ingredients like mushrooms, certain types of cheese, and even the crust can pose a risk of toxicity to dogs.


Feeding your dog pizza on a regular basis can contribute to weight gain and obesity. The high-calorie content and unhealthy fat levels in pizza can quickly add up, leading to an increased risk of various health issues such as diabetes, heart disease, and joint problems. It’s essential to provide a balanced and nutritious diet to help your dog maintain a healthy weight.

Signs That Your Dog Ate Pizza And Needs Veterinary Attention

While sharing a slice of pizza with your furry friend might seem harmless, it is important to remember that dogs have different dietary needs than humans. In fact, certain ingredients commonly found in pizza can be harmful to dogs. If your dog managed to sneak a bite of your cheesy indulgence, it’s crucial to be aware of the signs that indicate your dog may need immediate veterinary attention. Keep an eye out for the following symptoms:

Behavioral Changes

One of the first signs that your dog may require veterinary attention after consuming pizza is a significant change in behavior. Dogs that have ingested pizza may exhibit restlessness, aggression, or anxious behavior. This could include excessive barking, pacing, or irritability. These behavioral changes can be a result of the ingredients in pizza affecting their central nervous system. It is important to take note of these behavioral shifts and contact your veterinarian for guidance.

Digestive Issues

Pizza, especially if it contains toppings like onions, garlic, or spicy ingredients, can wreak havoc on your dog’s digestive system. Common digestive issues that may arise after a pizza feast can include vomiting, diarrhea, or constipation. These symptoms indicate that your dog’s stomach is struggling to process the ingredients and requires medical attention to prevent further complications. Monitor your dog’s stool and be prepared to discuss any abnormalities with your veterinarian.


If your usually energetic and playful dog suddenly becomes lethargic and lacks interest in activities, it could be a sign that they are experiencing discomfort after consuming pizza. Lethargy is a common symptom of digestive distress or even food poisoning in dogs. It is important to seek veterinary attention as soon as possible to address the underlying cause and prevent potential complications.

Excessive Thirst Or Urination

If you notice a significant increase in your dog’s water intake and subsequent urination after they have eaten pizza, it could indicate a potential issue. The high sodium content in pizza can lead to dehydration and imbalances in your dog’s electrolytes, causing excessive thirst and urination. This abnormal behavior is a clear indicator that veterinary attention is needed to ensure your dog’s hydration levels and overall health.

Difficulty Breathing

In severe cases, certain ingredients in pizza, such as onions or tomatoes, can trigger allergic reactions or respiratory distress in dogs. If you observe your dog experiencing difficulty breathing, coughing, wheezing, or swelling around the face or throat, it is crucial to seek immediate veterinary assistance. These symptoms can be signs of a potentially life-threatening condition and should not be ignored.

If you notice any of these signs after your dog has consumed pizza, it is vital to contact your veterinarian promptly. Remember to keep pizza and other human foods out of your dog’s reach to prevent such situations in the future. Prioritizing your dog’s health and well-being is essential for ensuring a happy and healthy life together.
