Peace lilies are distinguished by their large white flowers and glossy green leaves. The contrasting combination of white and green makes for a beautiful addition to your home.

The peace lily is a flowering plant that belongs to the family Araceae. The plant is native to tropical regions of Central and South America and Southeast Asia.

The plant has earned its reputation for being a good indoor option. They thrive well in areas with low sunlight. They can also tolerate fluorescent lights. So, a peace lily plant can be a good addition to your office desk as well.

You can water the peace lily plant once a week. Spray water on the leaves to keep the plant hydrated. The plant often starts drooping to let you know it needs water.

Peace lilies also have air-purifying qualities. In addition, it can help break down toxic gases like carbon monoxide and formaldehyde. So far, the plant sounds great, so why is it toxic for pets?

Are Peace Lilies Toxic to Dogs?

The mere presence of the peace lily plant will not harm your pet. As long as you can keep the dog away from the plant, all is good.

But if your dog is curious, as most dogs usually are, and it will not leave your houseplants alone, then it is a cause for concern.

Peace lilies, right from the stem, and leaves to their bloom, contain a compound known as calcium oxalate crystals. Unfortunately, the compound can be toxic for animals and humans alike if the plant is chewed or consumed.

These crystals come out of the damaged parts of the plant. Also known as raphides, these crystals are insoluble. When they come into contact with tissue, they remain persistent. These microscopic crystals embed themselves into the tissue and cause irritation and numbness.

If your dog bites into a peace lily plant, the damaged plant cells open up and shoot needle-sharp crystals into the dog’s mouth. The immediate reaction will be inflammation and pain around the mouth. This should deter the pet from eating the plant anymore.

But, if the dog does not back off and keeps chewing on the plant, it could lead to peace lily poisoning.

If the dog licks or bites a peace lily plant, you might see symptoms like:

  • Oral irritation
  • Intense burning of the mouth
  • Swelling of lips
  • Swelling of tongue
  • Numbness around the exposed area
  • Swelling of throat
  • Change in vocalizations
  • Difficulty breathing
  • Excessive rubbing around the mouth
  • Excessive drooling
  • Difficulty swallowing

If the dog has chewed and swallowed a part of the plant, you might see symptoms like:

  • Vomiting
  • Diarrhea
  • Loss of appetite
  • Swelling of abdomen
  • Inflammation of the GI tract
  • In severe cases, heart problems

If the dog has ingested the plant, it will start to show these symptoms in two hours. The severity of the symptoms depends on how much plant the dog has consumed.

In the rare case, the dog consumes a large quantity of peace lily, which could lead to liver or kidney damage. This scenario is rare because the initial burning and pain push the dog away from sampling any more of the plant.

If you see a chunk of the plant missing, it is best not to wait and contact your vet immediately.

You do not have a peace lily plant at home. Instead, your dog had a bite of the plant outdoors or at a friend’s place. So, how does the vet know it is peace lily poisoning?

When you start seeing the symptoms mentioned above and have no clue what the dog might have ingested, it would be best to visit the vet clinic for examination.

If the dog is vomiting, the vomit can be examined to see if there are any plant materials in it. The vet might also do a blood test or urine analysis to rule out other causes.

Do not leave the dog alone, without any supervision, in an unfamiliar location. When going out for walks, do not let them wander off. You never know what your curious pet can bite into or swallow.

What Are the Treatment Options Available for Peace Lily Poisoning?

If you catch the dog licking or biting into the peace lily plant, quickly get them away from the plant. Check its mouth to see if any plant materials are sticking to its tongue, gums, or teeth. Carefully remove the material, if any.

Next, give your dog’s mouth a good rinse with fresh water. The calcium oxalate crystals can really latch on to the tissue. So, it would be good to repeat the rinsing process a few times.

Offer the dog something cold like ice cubes to soothe the irritation. Ice can also help bring down the swelling inside the mouth. Likewise, milk can help soothe throat irritation.

If the dog has not swallowed any part of the plant and the symptoms are mild, these treatment options should be enough. However, continue to monitor the pet for any symptoms for the next several hours. The symptoms might take up to 12 hours to surface in some cases.

If it has been less than four hours since the dog ingested peace lily, the vet can try to induce vomiting to get the plant out of its digestive system. Please do not try to do this step on your own. The vet will examine the pet’s condition and will safely induce vomiting only if necessary.

If the dog is in pain, the vet can prescribe a pain reliever. If the dog is dehydrated from all the vomiting or diarrhea, it might need an intravenous drip. The vet may also prescribe medications to reduce swelling and inflammation of the digestive system.

If the swelling is excessive or your dog has severe difficulty in breathing, it might have to stay at the vet’s clinic until its symptoms subside.

Be smart with vase placement if you want to decorate your home with a bouquet of lilies. Keep them at a height that the dog cannot reach.
