Pizza Crust

Can Dogs Eat Pizza Crust?

Pizza is one of the most consumed –and delicious- foods ever existed on earth. It is incredibly popular in modern culture and is the staple party food.

Pizza, while not the healthiest food, is extremely alluring as it is full of appetizing ingredients and has a flavor that will cause the mouth of any dog, or person, to water. You may find yourself thinking, “Well, this food is meant to be shared,” especially when you encounter the puppy eyes of your four-legged baby, and be tempted to have him/her have a little bit of taste.

However, you should refrain from letting your pooch eat pizza if you want to keep him healthy. Pizza simply lacks the nutritional content that may be beneficial for dogs. It can cause harm as it typically contains many toppings that are harmful. Processed meat toppings that are not fresh and sauced and salted ingredients lead to numerous problems such as heart diseases and obesity.

And what about pizza crust? You have finished eating your pizza, and now a few crusts are laying around, should you give them to your dog? Well, no.

Why is Pizza Crust Bad for Dogs?

Pizza crust may not contain unhealthy ingredients like pizza, but it is not a good idea to let your dog chew down on it. Most likely, it will contain ingredients toxic to dogs, such as garlic.

Moreover, pizza crust, similar to the pizza itself, has a lot of carbohydrates, which is nothing but empty calories for canines. Having too much of it may lead to weight gain, gastrointestinal upsets, diabetes, and lethargy.

Now let us inspect the ingredients and their effects on dogs in-depth to understand why exactly pizza and pizza crust is bad for dogs.

Ingredients to Stay Away

The ingredients given below pose a threat to the health of your canine companion. Even if your pizza does not seem to contain some of these ingredients, it is still a bad idea to feed it to your dog as you probably don’t know what kind of an environment the pizza was made in.

Simple Carbs

Both the pizza itself and the crusts contain a large amount of sodium and empty calories that have no nutritional value that offers any benefit to your dog. These are simple carbohydrates.

What’s so bad about empty calories is that they will make your pooch feel full and prevent them from eating healthy food, while increasing their blood pressure and leading them to put on weight. Moreover, your dog may have difficulty digesting baked bread, which causes a significant decrease in the energy levels in the long term.

High Fat

One of the reasons pizza tastes so amazing is that it is covered with an excessive amount of grease. Even if your local pizza store claims to bake low-fat pizzas, there’s a chance it may still contain a form of unhealthy grease.

Dietary requirements of dogs are different than humans, and they should have no more than 10% fat content in their diets. If your dog regularly consumes more than this limit, it will lead towards obesity, and consequently, pancreatitis. Both conditions are fatal and hard to get rid of for dogs, so monitor your pooch’s fat intake if you want to keep them healthy.

Onion and Garlic

Onions and garlic are great for flavoring a pizza, but a dog should never consume them as they are toxic to them, especially garlic. They belong to the allium family of plants, which contain a compound called thiosulphate.

This compound reduces the oxygen levels in red blood cells. Upon consumption, your dog may experience various symptoms ranging from a mild stomach upset to hemolytic anemia, depending on your dog’s overall health and the amount consumed.

The last one is a really serious condition that, while being fatal, can lead to difficulty in breathing, dehydration, and lethargy. Ultimately, your dog may fall into a coma and die.

They may be hard to notice in the pizza at first glance as they may be mixed with the bread or the tomato sauce. Considering that even a small amount of garlic or onion can inflict great harm to your dog’s health, it is not worth the risk.

Can Dogs Eat Pizza Crust


Even though cheese is an animal product, it is not the best thing to give your dog. Most, if not all, dogs suffer from lactose intolerance. That does not mean that all kind of cheese is harmful to dogs, however, the kind that’s widely used in pizzas is usually dangerous. Most pizzas are covered in a large amount of low quality, fatty cheese, which is very difficult for your four-legged baby, that has an innate intolerance to dairy products, to digest.

Consuming a large amount of cheese may cause digestive problems such as vomiting and diarrhea. Even if your pizza’s crust does not seem to contain any cheese, it has been in close contact with it, so there’s always a risk.


A large number of toppings on a pizza, such as pickled vegetables, tomato sauce, and pepperoni, contain a high amount of salt in order to preserve it and make it tasty. High sodium intake may lead to your dog experiencing high blood pressure and gastrointestinal problems.

Conclusion: Can Dogs Eat Pizza Crust?

In short, it is best to keep your dog away from pizza or its crust. Especially if you have a puppy, as their digestive systems are a lot more fragile than adult dogs. They will most likely enjoy the taste, but it is just not worth the risk.

Do not be alarmed if your pop has a taste of some pizza crust. Unless it does not eat a large amount, chances are it will get an upset stomach at worst. However, if your dog has eaten more than a small piece of pizza or pizza crust, or shows discomfort, immediately gather as much information about the contents of the pizza and call your vet.
