Why Are Peace Lilies Dangerous to Dogs?

The danger posed by peace lilies to dogs stems from the presence of calcium oxalate crystals within their tissues. When dogs, driven by their natural curiosity or perhaps a touch of boredom, decide to sample the leaves or other parts of the peace lily, these microscopic crystals come into play.

Causes of Peace Lily Poisoning in Dogs

Peace lily poisoning occurs when a dog ingests any part of the plant, whether it’s the leaves, stems, flowers, or even the pollen. The calcium oxalate crystals within these plant parts can lead to a range of health issues in dogs.

What Should I Do If My Dog Has Eaten a Peace Lily?

If you suspect that your dog has ingested a peace lily, prompt action is crucial. Here’s a step-by-step guide on how to handle this worrisome situation:

1. Contact Your Veterinarian

The moment you realize that your dog may have consumed a peace lily, get in touch with your veterinarian immediately. Provide them with as much information as possible, including the type of plant ingested, the amount (if known), and your dog’s current symptoms, if any.

2. Observe Your Dog

Keep a close eye on your furry friend. Watch for any signs of distress or unusual behavior. While symptoms may not manifest immediately, early detection is vital.

3. Do Not Induce Vomiting

Unlike some other types of poisoning, it’s generally not recommended to induce vomiting in cases of peace lily ingestion. This is because vomiting can further irritate the mouth and throat due to the presence of calcium oxalate crystals.

4. Diagnosing Plant Poisoning in Dogs

Your veterinarian will perform a thorough examination and may order diagnostic tests, such as bloodwork and urinalysis, to assess your dog’s overall health and the extent of the poisoning.

5. Symptoms of Peace Lily Poisoning in Dogs

The symptoms of peace lily poisoning in dogs can vary in severity and may include:

  • Excessive drooling
  • Pawing at the mouth
  • Difficulty swallowing
  • Vomiting
  • Diarrhea
  • Lethargy
  • Loss of appetite
  • Tremors or seizures (in severe cases)


The treatment for peace lily poisoning in dogs typically focuses on managing the symptoms and providing supportive care. Treatment measures may include:

1. Supportive Care

Supportive care may involve intravenous (IV) fluids to prevent dehydration and electrolyte imbalances. Your veterinarian may also administer medications to control vomiting and reduce discomfort.

2. Activated Charcoal

Activated charcoal may be used to absorb any remaining toxins in the gastrointestinal tract.

3. Medications

In severe cases of poisoning, your dog may require medications to manage symptoms like tremors or seizures.

4. Monitoring

Your veterinarian will closely monitor your dog’s condition throughout the treatment process, ensuring that any complications are promptly addressed.

Recovery of Peace Lily Poisoning in Dogs

The recovery of a dog from peace lily poisoning depends on various factors, including the amount ingested, the specific parts of the plant consumed, and the dog’s individual sensitivity. With prompt and appropriate treatment, many dogs do recover. However, severe cases can lead to complications and may even be fatal.

4. Monitor Outdoor Plants

If you have peace lilies in your garden or outdoor spaces, be vigilant when your dog is outside. Ensure that they don’t have access to these plants during playtime or walks.

5. Are All Parts of the Peace Lily Poisonous to Dogs?
