can dogs eat croutons

As responsible dog owners, their health and wellbeing is our top priority. This often prompts us to question whether certain human foods are suitable for our dogs. One such query revolves around croutons – those crispy, flavorful cubes of toasted bread often used to adorn salads and soups. But can dogs eat croutons?

While croutons are a popular, delicious snack for humans, they should not be given to dogs as they often contain toxic ingredients, such as garlic and onion.

Let’s find out more about why croutons are a bad choice for your dog.

What Are Croutons?

Before we address the question “Can dogs eat croutons?”, Let understand what they actually are. Croutons are small, toasted or fried pieces of bread that are often used as toppings for salads, soups, and other dishes to add texture and flavor. They are typically made from bread that has been cubed or sliced into small pieces and then seasoned before being toasted or fried until they become crispy and golden brown.

Croutons can come in various shapes, sizes, and flavors, ranging from plain to seasoned with herbs, spices, and even cheese.

Can Dogs Eat Croutons?

Can dogs eat croutons? The simple and straightforward answer is no, dogs should not eat croutons. Croutons are usually seasoned with various herbs, spices, garlic, and onion powders to enhance their flavor. These ingredients, especially garlic and onions, are toxic to dogs and can lead to serious health issues.

Additionally, croutons are often high in salt and unhealthy fats, which can contribute to obesity and cardiovascular problems in dogs. While croutons might seem harmless on the surface, their ingredients and nutritional content make them unsuitable for canine consumption.

Aside from the potential health complications, croutons lack essential nutrients that dogs need for their overall health and well-being. Dogs require a balanced diet that provides them with the right proportions of protein, carbohydrates, fats, vitamins, and minerals, which croutons do not offer.

Potential Risks of Feeding Croutons to Dogs

To truly understand why croutons are not suitable for dogs, let’s take a closer look at some of the common ingredients used to make them:

Garlic and Onion

Garlic and onions are part of the Allium family of vegetables and contain compounds that can cause oxidative damage to dogs’ red blood cells, leading to a condition called hemolytic anemia. Even small amounts of garlic or onions, such as those found in seasoned croutons, can be harmful to dogs, potentially causing symptoms like vomiting, diarrhea, abdominal pain, lethargy, and even more severe complications.


Croutons are often seasoned with salt to enhance their flavor. While salt is an essential mineral for dogs, too much of it can be harmful. Excessive salt intake can lead to electrolyte imbalances, dehydration, increased thirst, and even sodium ion poisoning. Symptoms of sodium ion poisoning include vomiting, diarrhea, lethargy, tremors, seizures, and in severe cases, it can be fatal. Dogs have a lower tolerance for salt compared to humans, so the sodium content in croutons can be particularly concerning.

Unhealthy Fats

Many croutons are fried or toasted in unhealthy fats, such as oils with high saturated or trans fat content. These fats are detrimental to dogs’ health, as they can lead to obesity, pancreatitis, and other cardiovascular issues. Obesity in dogs is associated with joint problems, diabetes, and reduced overall quality of life. Pancreatitis, inflammation of the pancreas, can result in severe abdominal pain, vomiting, diarrhea, and even life-threatening complications.

Herbs and Spices

The various herbs and spices used to flavor croutons might be harmless for humans, but dogs can react differently to them. Some herbs and spices can cause digestive upset, allergic reactions, or other adverse effects in dogs. It’s best to err on the side of caution and avoid introducing these ingredients into your dog’s diet.

Additives and Preservatives

Croutons often contain various additives and preservatives to prolong their shelf life and enhance their taste. These additives might include artificial flavors, colors, and chemicals that can be difficult for dogs to metabolize and could potentially lead to gastrointestinal distress or allergic reactions.

Can Dogs Eat Homemade Croutons?

Even if homemade, it’s important to be cautious about feeding croutons to dogs. While homemade croutons might not contain some of the additives and preservatives that store-bought ones do, the potential risks associated with the ingredients used in croutons still apply.

Remember that these croutons should always be given in moderation as a treat and should never replace a well-balanced, nutritious diet.

Homemade Dog-Friendly Croutons:


  • Whole wheat or grain-free bread (avoid using bread with garlic, onions, or other harmful ingredients)
  • Olive oil or coconut oil


  1. Prepare the Bread: Choose a whole wheat or grain-free bread that doesn’t contain any toxic ingredients like garlic or onions. Check the ingredient list to ensure it’s safe for dogs. Cut the bread into small cubes or bite-sized pieces.
  2. Preheat the Oven: Preheat your oven to 350°F (175°C).
  3. Coat with Oil: Lightly coat the bread cubes with a small amount of olive oil or melted coconut oil. This will help the cubes become crispy during baking.
  4. Spread on Baking Sheet: Arrange the oiled bread cubes on a baking sheet in a single layer. Make sure they are not too crowded to ensure even toasting.
  5. Bake: Place the baking sheet in the preheated oven and bake for about 10-15 minutes, or until the bread cubes are golden brown and crispy. Keep a close eye on them to prevent overcooking.
  6. Cool: Once the croutons are baked, remove them from the oven and allow them to cool completely before offering them to your dog.
  7. Store: Store the homemade croutons in an airtight container in a cool, dry place. These treats can be given to your dog as an occasional snack.

Important Notes:

  • It’s essential to use bread that does not contain toxic ingredients like garlic, onions, or artificial additives. Plain whole wheat or grain-free bread is a safer option.
  • Remember to use olive oil or coconut oil in moderation, as excessive fat intake can lead to health issues for dogs.
  • Always consult your veterinarian before introducing any new treats or ingredients into your dog’s diet, especially if your dog has any underlying health conditions or dietary restrictions.

My Dog Ate Croutons, What Should I Do?

If your dog has accidentally consumed croutons or any other potentially harmful food, it’s important to take prompt and appropriate action to ensure their safety. Here are some steps to follow if your dog eats croutons:

1. Assess the Situation: Determine how many croutons your dog has ingested and if any potentially harmful ingredients, like garlic or onions, were present. The quantity and ingredients will help you gauge the potential risk.

2. Contact Your Veterinarian: If you suspect your dog has consumed a significant amount of croutons or if the croutons contained toxic ingredients, contact your veterinarian immediately. They can provide guidance based on your dog’s size, health, and the ingredients involved.

3. Observe for Symptoms: Keep a close eye on your dog for any signs of distress, discomfort, or unusual behavior. Symptoms of concern might include vomiting, diarrhea, lethargy, excessive drooling, abdominal pain, or changes in behavior. If you notice any of these symptoms, seek veterinary attention.

4. Induce Vomiting (If Advised by a Vet): In some cases, your veterinarian might recommend inducing vomiting to prevent further absorption of harmful substances. However, never induce vomiting without consulting a veterinarian first, as it might not be appropriate or safe for all situations.

5. Provide Fresh Water: Offer your dog fresh, clean water to help flush their system and prevent dehydration. Be sure to monitor their water intake.

6. Avoid Sharing Human Foods: To prevent similar incidents in the future, it’s essential to keep human foods, especially those that are potentially harmful to dogs, out of their reach. Educate family members and guests about not sharing inappropriate foods with your dog.

7. Stick to Regular Diet: Until your veterinarian provides guidance, stick to your dog’s regular diet and avoid offering additional treats or table scraps. This will help minimize the risk of any further digestive issues.

8. Monitor for 24 Hours: Even if your dog appears fine initially, it’s a good idea to monitor them for at least 24 hours after consuming croutons. Some symptoms might not appear immediately and could develop over time.

Remember, the best course of action is to consult your veterinarian. They can provide personalized advice based on your dog’s specific situation. It’s always better to be cautious and seek professional guidance if you’re uncertain about your dog’s health after they’ve ingested something potentially harmful.

Signs of Onion and Garlic Toxicity in Dogs

Onion and garlic are part of the Allium family of vegetables and contain compounds that can be toxic to dogs. The symptoms of onion and garlic poisoning can vary depending on the amount ingested, the size of the dog, and their individual sensitivity. Here are some common symptoms of onion and garlic poisoning in dogs:

1. Gastrointestinal Distress:

The ingestion of onion and garlic can lead to severe gastrointestinal distress in dogs. This distress arises from the toxic compounds present in these ingredients, causing a range of negative effects on the digestive system and overall well-being of the animal, including:

  • Vomiting
  • Diarrhea
  • Loss of appetite
  • Abdominal pain or discomfort

2. Hemolytic Anemia:

One of the most concerning effects of onion and garlic poisoning in dogs is the potential to cause hemolytic anemia. This condition involves the destruction of red blood cells, which can lead to symptoms such as:

  • Weakness
  • Lethargy
  • Rapid breathing
  • Pale or jaundiced (yellow) gums
  • Dark urine
  • Rapid heart rate

4. Elevated Heart Rate and Respiratory Rate

Due to the lack of oxygen-carrying capacity of damaged red blood cells, your dog’s body might try to compensate by increasing the heart rate and respiratory rate.

5. Lethargy and Weakness

Dogs suffering from onion and garlic poisoning might become lethargic and weak, as their bodies struggle to cope with the effects on their red blood cells.

6. Collapse or Unconsciousness (Severe Cases):

In severe cases of onion and garlic poisoning, a dog’s condition can deteriorate to the point of collapse, unconsciousness, or even death.

It’s important to note that the symptoms of onion and garlic poisoning might not appear immediately after ingestion. They can take a few days to manifest, especially when it comes to the development of hemolytic anemia. If you suspect your dog has ingested onions or garlic, even in small amounts, it’s advisable to seek veterinary attention as soon as possible. The earlier the treatment, the better the chances of a positive outcome.

Remember that any amount of onion or garlic, including those found in foods like croutons, can be harmful to dogs. If your dog shows any symptoms of onion or garlic poisoning, contact your veterinarian immediately for guidance and treatment.

Better Alternatives to Croutons For Dogs

6. Frozen Treats: Create frozen treats by blending dog-safe fruits like bananas and berries with a bit of water and freezing the mixture in ice cube trays. These frozen treats can be a refreshing option on hot days.

7. Commercial Dental Chews: Choose dental chews that are designed to promote dental health while offering your dog a satisfying chew.

8. Vegetables with Nutritional Value: Vegetables like green beans and sweet potatoes (cooked and plain) can provide fiber and nutrients without the harmful ingredients found in croutons.


In the grand scheme of things, the question “can dogs eat croutons” serves as a reminder that not all human foods are suitable for our four-legged companions. While it might be tempting to share our meals with them, it’s crucial to prioritize their health and well-being.

Croutons, with their potentially harmful ingredients and high sodium content, are best kept away from dogs’ diets. Instead, opt for dog-friendly treats and foods that are specifically designed to meet their nutritional requirements.
