Can Dogs Eat Lasagna?

Although lasagna originated in Italy, it is famous all over the globe. It is easy to mass-produce, and you can use it to cater for large events or make fast versions that you can reheat at home.

Lasagna is a fantastic pasta dish. If you don’t feel like eating it all, you might consider sharing leftover lasagna with your dog. But can dogs eat lasagna?

We don’t recommend you feed your dog lasagna. Because of the high-fat content, lasagna is not good for dogs. Additionally, some ingredients can even be toxic for our dogs.

Consult a veterinarian if you are unsure about the implications of feeding garlic or onions to your dog.

What is Lasagna?

Lasagna is an Italian pasta made from rolled pasta and formed into noodles that are then cut into long strips for use in cooking. The dish’s name is more often used to describe the dish than the sheets of pasta.

The most popular lasagna recipe is made with alternating layers of ragu (a tomato-based sauce that includes mince, onions, and other vegetables) and lasagna sheets. The white sauce (a cream mixture of milk, butter, and flour) is used to bind it all.

Do Dogs Like Lasagna?

Lasagna is a delicious, rich, salty, and meaty smell dish that is appealing to dogs (however, some dogs might disagree).

The dish’s vegetarian or vegan version may not be as appealing to dogs because they do not contain meat and dairy ingredients.

Can Dogs Eat Lasagna?

The short answer is no. It is a great dish that everyone loves to eat, no matter if it is made at home or in a restaurant.

The most common ingredients in lasagna are ground beef, pasta, tomato sauce, cheese, and various seasonings.

Lasagna is a dangerous dish that contains many unhealthy and even toxic ingredients for dogs.

Lasagna is Not Safe for Dogs

As mentioned above, lasagna is often made with garlic, onions, and tomato sauce, which are poisonous and can be dangerous for dogs. The lasagna may also be hazardous if your dog is lactose intolerant.

Below are some of the possible dangers your pet could face if they ingest any of these toxic components.

Garlic and Onion

Onions and garlic are the most harmful ingredients to dogs’ health. On the other hand, a small amount of onion and garlic will not cause any problems. For example, if your dog is 20 pounds in weight, you should limit his intake to 0.001 pounds of onion or garlic.

Anemia (a decreased number of hemoglobin and red blood cells) may occur if your dog eats a lot of onion and garlic.

Lasagna can contain a lot of minced or chopped garlic and onions. If a dog accidentally eats a whole Lasagna dish, this can lead to poisoning and even death


Salt (sodium), a natural component of your dog’s diet, can cause severe sickness or even death.

Sodium chloride can cause sodium poisoning because it is essential for the body to maintain a healthy water level.

These are the most common symptoms of salt poisoning in dogs:


A small amount of black pepper is considered to be healthy for dogs. However, large amounts can cause stomach upsets.


Oregano plants can be grown commercially for culinary purposes. Although this spice isn’t extremely harmful, it can cause severe digestive problems in your pet, including vomiting and diarrhea. In severe cases, it can also cause stomach ulcers, a slower heartbeat, and lower blood pressure.

Tomato Sauce

Tomato sauces can be dangerous for dogs due to added sugar, salt, and artificial flavors or chemicals. Although small amounts of tomato-based products, such as sauce, won’t cause any harm to your dog, excessive consumption can lead to vomiting or diarrhea that could become more serious.


If your dog is lactose-intolerant, avoid cheese and other dairy products.

Cheese consumption may cause vomiting or diarrhea. Cheese should only be eaten in moderation if your dog can tolerate dairy products.

Which Dogs Shouldn’t Eat Lasagna?

Some health conditions could make lasagna more dangerous for dogs.

Dogs can be allergic to or intolerant to certain foods like wheat, gluten, milk, and different proteins. Lasagna is not recommended for dogs with food allergies or those who have upset stomachs.

Some lasagna recipes have high salt content. Dogs suffering from heart disease or kidney disease or taking potassium bromide for seizures should avoid eating large quantities of salt.

Factors That Could Alter Toxicity

There are many other factors to consider before offering lasagna to your dog.

  • Size of the dog

The size of your dog is a key factor in determining whether or not it will be susceptible to lasagna poisoning.

One bite of lasagna may not be as harmful to an adult dog as it is to a puppy 3 to 6 months old.

  • The Dog’s Breed

The breed is another factor. Some dog breeds are predisposed to toxic effects from garlic and onion, much like our allergies. If the dog is not treated promptly, even the smallest bite can cause serious problems that could result in death.

Japanese breeds such as the Shiba Inu, Akita Inu, and dogs with similar genetic patterns would be extremely vulnerable to toxic effects from lasagna’s onion or garlic.

  • Underlying Gastrointestinal Conditions

If your dog has gastrointestinal or stomach problems such as diarrhea, GI distress, or lactose intolerance, the lasagna toxicity situation will worsen. So, if your dog has already been diagnosed with this condition, it is best to avoid feeding it lasagna.

What Happens When a Dog Eats Lasagna?

Lasagna in its original form may not pose any danger to dogs. It is the ingredients that can cause problems for your dog’s health. The biggest threats found in lasagna are onions and garlic, which can cause severe oxidative damage to your dog’s internal organs.

You can give your dog one clove of garlic or onion, and it won’t cause any harm. But, any more than that can cause serious side effects that could worsen if you give your dog a higher dose.

Hemolytic anemia can be caused by excessive garlic and onion consumption in dogs, which can lead to the destruction of their RBCs and eventually the loss of the ability to carry oxygen throughout your body.

Your dog could become sick if there is not enough oxygen in its body. Consuming too much onion or garlic can also lead to death or serious health problems for your dog. It is best to get your dog to the veterinarian immediately if they have eaten too many lasagnas or show signs of toxic effects.

If the dog has not yet digested the lasagna, the vet will attempt to induce vomiting.

In other cases, the vet might opt to administer a blood transfusion to increase blood oxygen saturation.

It is easy to see how troublesome and dangerous it can be for you and your pet, so it is best not to give it lasagna.

Can Lasagna Be Fatal For My Puppy?

Yes, lasagna can cause death in dogs, depending on the factors mentioned. This is especially true for lasagna with onion and garlic. It could prove fatal for your dog, especially a small puppy, as it can die from even one bite of the onion.

These are the most common signs of onion and garlic toxicity:

  • Breathing problems
  • Vomiting
  • Reduced appetite
  • Lethargy
  • Wining sounds
  • Reddish Urine
  • Fainting
  • Weakness

The situation can be life-threatening and may require urgent medical attention, so you should immediately take your puppy to the vet.

Puppies could also have a problem with cheese, as their digestive health is not strong enough to handle such complex fats.

When Should You Visit Your Vet?

Prevention is better than cure when it comes to your dog. It is best to not allow your dog to eat lasagna.

However, if your dog does eat lasagna, it is crucial to call your veterinarian immediately and get some advice.

Your veterinarian will recommend preventive measures to stop the condition from getting worse. If you cannot track your dog’s symptoms, immediately take him to the vet to provide better treatment.

How to Cook Special Lasagna for your Dog?

Even though it may not be called “lasagna”, your dog can still enjoy a few pieces of this home-cooked version as long as it does not contain any harmful ingredients. You can only substitute these ingredients for items that are good for your dog’s health.

These ingredients are the best way to make home-cooked lasagna:

Avoid using cheese if your pooch has lactose intolerance. Before you add the meat to the noodles, drain the grease. Bake your noodles according to the traditional baking method until they are soft.

Then, let it cool for at least an hour. Even though dog-friendly lasagna isn’t as delicious as the original, you can feed your dog without any side effects, so it can live a happy and healthy life.


You should not feed leftover lasagna to your pet. Like most table scraps, lasagna has ingredients that are safe and ingredients that can be dangerous for dogs, so knowing which human foods are potentially hazardous for your dog is essential.

Ensure your dog is tested for allergies such as lactose intolerance or GI problems. If you are adding garlic and onions to your recipe, be sure to keep the dish away from your dog. You want your pet to be happy and healthy.

You can make lasagna for your dog if you want. All you have to do is remove all the harmful ingredients and substitute them with food safe for your dog.
