Peace lilies are popular houseplants known for their elegant appearance and air-purifying qualities. Although they add a touch of beauty to our homes, it’s important to understand the potential risks they pose to our beloved pets, especially dogs. The question arises, is peace lily toxic to dogs?

The answer is yes, peace lilies can be toxic to dogs. The plant contains insoluble calcium oxalate crystals, which are responsible for causing oral irritation, intense burning of the mouth, tongue, and lips, excessive drooling, vomiting, and difficulty swallowing when ingested by dogs. Our furry companions may encounter these issues even if they consume only a small amount of the plant or its pollen.

As a responsible pet owner, it’s essential to be aware of the potential dangers surrounding your dog in your home environment. Recognizing toxic plants, such as the peace lily, can help you prevent accidents and keep your pet safe and healthy.

Is Peace Lily Toxic to Dogs?

Yes, peace lilies are indeed toxic to dogs. The plant contains insoluble calcium oxalate crystals which, when ingested, can cause serious health problems in our canine companions. If a dog chews on any part of the peace lily, it can experience intense burning and irritation in the mouth, tongue, and lips. This can lead to excessive drooling and difficulty swallowing.

The ingestion of peace lily can also cause gastrointestinal problems in dogs. These symptoms include vomiting and diarrhea. Depending on the amount of the plant consumed, the severity of the symptoms can range from mild to severe. In rare cases where a dog ingests a large portion of the peace lily, it may show signs of breathing difficulty due to an inflamed airway.

It’s essential to keep an eye on your dog and prevent it from accessing peace lilies as houseplants or in your garden. If you suspect that your dog has ingested any part of a peace lily, it’s crucial to seek immediate veterinary assistance. The vet will be able to assess the severity of the situation and provide appropriate treatment to manage your dog’s symptoms.

In summary, it’s important to be aware of the potential dangers peace lilies pose to dogs. By being mindful of where you place these plants and watching your dog closely, you can help protect your furry friend from accidental poisoning by peace lilies. Remember, it’s always better to be cautious when dealing with potentially harmful plants around your pets.

Symptoms of Peace Lily Poisoning

Oral Irritation

When dogs consume peace lilies, one of the first symptoms to emerge is oral irritation. The plant contains insoluble calcium oxalates which cause intense burning and irritation in a dog’s mouth, tongue, and lips. This discomfort may lead the animal to paw at their face or mouth in an attempt to alleviate the pain.


Another common symptom of peace lily poisoning in dogs is excessive drooling. The irritation caused by the calcium oxalates in the plant triggers an increased production of saliva. The drooling can be quite severe, as the dog’s body attempts to flush out the harmful substances to protect itself.


As the dog’s digestive system reacts to the calcium oxalates and other toxic components of the peace lily, vomiting is a likely outcome. This symptom can provide an important clue to pet owners that their dog may have ingested this harmful plant.

Difficulty Swallowing

Swallowing can become difficult for dogs that have consumed peace lilies. The insoluble calcium oxalates cause intense burning and irritation, not only in the mouth but also in the throat. Consequently, the dog may struggle to swallow food or drink water, further exacerbating their discomfort.

Loss of Appetite

Lastly, a dog suffering from peace lily poisoning may experience a loss of appetite. This is likely due to the combination of oral irritation, difficulty swallowing, and general discomfort caused by the toxic plant. The animal’s refusal to eat can result in lethargy and overall weakness as their body struggles to cope with the adverse effects of the poisoning.

It is essential for pet owners to be aware of these symptoms and to seek veterinary attention immediately if they suspect their dog has ingested a peace lily. Timely intervention can make all the difference in helping the dog recover from this potentially dangerous situation.

Causes of Peace Lily Toxicity

Peace lilies, also known as Spathiphyllum, are popular houseplants due to their beautiful appearance and low maintenance requirements. However, they can be toxic to dogs if ingested. In this section, we will discuss the main cause of peace lily toxicity to dogs and its effects on their health.

Oxalate Crystals

Peace lilies contain insoluble calcium oxalate crystals in all parts of the plant. When dogs chew or swallow these crystals, they can experience a variety of symptoms and health issues. The main reason for the toxicity is the abrasive effect of these crystals on the soft tissue of the mouth and gastrointestinal tract of the dog.

Oral Irritation and Pain

When a dog consumes parts of a peace lily, the presence of oxalate crystals can cause oral irritation and intense burning sensations in their mouth, tongue, and lips. This, in turn, leads to excessive drooling, difficulty swallowing, and in some cases, even vomiting.

Digestive Problems

In addition to oral irritation, dogs that ingest peace lily may also experience gastrointestinal issues, such as diarrhea. These symptoms are caused by the oxalate crystals when they come in contact with the lining of the dog’s digestive system, leading to inflammation and discomfort.

Breathing Issues and Other Symptoms

As the dog’s body tries to cope with the presence of oxalate crystals, some other symptoms may arise. These include labored breathing, hoarse barking, dilated eyes, and even potential airway obstruction. Additionally, numbness of the exposed area, cardiac arrhythmia, and loss of appetite may also be observed.

In conclusion, the primary cause of peace lily toxicity in dogs is the presence of insoluble calcium oxalate crystals found throughout the plant. These crystals can lead to a range of symptoms and health issues in dogs, especially when ingested. It is essential to keep peace lilies out of reach from dogs and be mindful of their potential to harm your furry friend.

Treatment Options

Immediate Home Care

If you find your dog has ingested a peace lily, it is important to take prompt action. Start by gently rinsing out your dog’s mouth with fresh water to remove as many of the irritating crystals as possible. Removing any plant material from their mouth, gums, or teeth can also help alleviate some of the discomfort caused by the toxic substance. Encourage your dog to drink water, which can help dilute the toxins.

You can also offer your dog ice chips or a small amount of ice cream to help soothe the burning sensation. These steps provide immediate relief and help prevent further irritation.

Professional Veterinary Care

For more severe cases or if your dog is experiencing difficulty breathing, it is advised to consult with a veterinarian promptly. The vet may prescribe steroids or anti-inflammatory medications to reduce swelling and inflammation caused by the toxic principles of the peace lily.

In certain situations, your veterinarian might recommend inducing vomiting with hydrogen peroxide if ingestion occurred recently, and you cannot reach the veterinary clinic in time. This helps remove any irritants still in the dog’s system.

Preventing Future Exposure

To avoid peace lily poisoning in dogs, it is crucial to take preventive measures. Follow these steps to keep your pet safe:

  • Keep peace lilies out of your dog’s reach, either by placing them in high or inaccessible areas or by using dog-proof containers.
  • Monitor your dog while outdoors, and do not allow them to ingest any plants.
  • Train your dog to avoid chewing on plants by providing them with appropriate toys and chews.
  • Regularly check the plants in your home and garden to ensure none pose a risk to your pet.

By following these guidelines, you can protect your dog from the harmful effects of ingesting a toxic peace lily and ensure their well-being.
