Can Dogs Eat Pesto? – No, They Can’t

When it comes to sharing our favorite foods with our furry friends, we must always consider their health and safety first. Pesto, a savory sauce that often graces our pasta, is a no-go for dogs. No, dogs should not eat pesto because of its classic ingredients like garlic, onion, and sometimes nuts, which are toxic to dogs. Giving your pup even a small amount can lead to serious health complications.

Can Puppies Eat Pesto?

Puppies are even more sensitive to certain foods than adult dogs, and pesto is certainly not an exception. No, puppies should never eat pesto. Their developing systems are not equipped to handle the toxic ingredients found in pesto, and consuming it could lead to more severe reactions than in adult dogs.

Why is Pesto Harmful for Dogs?

Pesto can be delicious for humans, but it contains multiple ingredients that pose serious health risks to dogs. Here’s why this favorite Italian sauce should stay off your dog’s menu:

Garlic and Onion Toxicity

Both garlic and onion are commonly used in pesto, and they belong to the allium family of plants which are poisonous to dogs. These ingredients can cause oxidative damage to a dog’s red blood cells, leading to anemia and related symptoms such as weakness, vomiting, and breathing difficulties.

Toxic Nuts

Some pesto recipes include nuts, such as pine nuts, which can be harsh on a dog’s digestive system. While not all nuts are toxic, dogs can struggle to digest them, and some like macadamia nuts, which might be used as a substitute, are very poisonous to dogs.

High Fat Content

The oil ingredient in pesto, while healthy for humans in moderate amounts, is high in fats which can cause pancreatitis in dogs. This inflammation of the pancreas is painful and can have serious health implications.

Symptoms to Watch Out For After Dogs Consume Pesto

  • Vomiting and Diarrhea: These are common signs of distress in dogs and can indicate that the pesto is not agreeing with their system.
  • Lethargy: If your dog is acting unusually tired or unenthusiastic, it could be a symptom of garlic or onion toxicity, especially after consuming pesto.
  • Abdominal Pain: If your dog seems to be in discomfort, especially around their stomach area, it could be a sign of pancreatitis or gastrointestinal upset.

Immediate Steps to Take if Your Dog Eats Pesto

  • Do Not Induce Vomiting: While it might seem like a good idea to get the pesto out of their system, this should only be done on the advice of a veterinarian.
  • Contact Your Vet: Call your veterinarian or emergency pet clinic as soon as possible for professional advice on the next steps to take.
  • Monitor Your Dog: Keep a close watch on your dog for any symptoms of distress and be prepared to provide your vet with information about what and how much they might have consumed.

Safe Alternatives to Pesto

While pesto is dangerous for dogs, there are safe alternatives that they can enjoy. Consider offering your dog these safer food options instead:

  • Carrots – Plain carrots are a great crunchy snack for dogs that also provide them with essential vitamins.
  • Apples – Apples (without seeds) can be a sweet treat and are good for a dog’s teeth.
  • Pumpkin – Pure pumpkin is healthy for dogs in moderation and can aid in digestive health.


Pesto may be a flavorful addition to our dishes, but it contains several ingredients that are hazardous to dogs. Remembering which foods are off-limits to our canine companions is crucial to prevent accidental poisoning. If you believe your dog has ingested pesto, contact your vet immediately. Fortunately, there are plenty of dog-friendly alternatives to pesto, ensuring our pets can still enjoy snack time safely.
