As pet parents, we all want to keep our dogs safe in their homes and out and about. There are lots of safe, pet-friendly plants that won’t cause any harm to your pup, but it’s essential to be aware of the ones that are dangerous and what to do if your furry friend gets his paws on them.

We often enjoy the strong and delightful smell of lilies, with their bold and beautiful flowers, but they may lead you to wonder, “Are lilies poisonous to dogs?”

The simple answer to this is yes. Lilies are poisonous to dogs. Some species are more toxic than others, but as a general rule, all types of lilies could be harmful to pets. Let’s walk through the different types of lilies and their potential dangers.

Which Lily Plants Are Poisonous to Dogs?

Lilies contain alkaloids, which cause damage to red blood cells. In cats, ingestion of lilies can cause organ failure and even death, but in dogs, this is rare. However, lilies can cause a very upset tummy and other problems. But with such a range of lily plants out there, are all types of lilies toxic?

All types of lilies could make your pup very sick. Some species are highly toxic, while others are more harmless.

Non-Toxic Varieties

Non-toxic varieties of lilies include the Peruvian lily, tiger lily, day lily, and Easter lily. These lilies are not particularly dangerous to your pet and are unlikely to cause any problems. However, you should still keep a close eye on your dog as the lilies could irritate the gut lining, so you may notice some mild vomiting or diarrhea.

Toxic Varieties

Toxic lily species include the Prairie Lily (rain lily), Lily of the Valley, Peace Lily, Calla Lily, Glory Lily, Japanese Show Lily, Leopard Lily, and Stargazer Lily.

Calla and Peace Lilies are particularly toxic. They release calcium oxalate crystals when chewed, which can cause burning and irritation to the inside of the mouth, lips, and skin. While Lily of the Valley could trigger a change in your dog’s heartbeat called an arrhythmia, which can be fatal. Daylilies and Easter Lilies are unlikely to cause your dog any problems, but they may cause some mild tummy upsets, such as vomiting and diarrhea.

Which Parts Of A Lily Plant Are Poisonous To Dogs?

All parts of the lily plant can be toxic to dogs—the flower, leaves, stems, roots, and bulbs.

The bulbs are especially poisonous, as this part of the plant contains toxic substances in higher concentrations. Pollen from lilies is not specifically harmful but can cause irritation and sneezing if inhaled.

Symptoms Of Lily Poisoning In Dogs

The symptoms of lily poisoning tend to start very quickly after ingestion, usually within the first two hours. However, symptoms can appear at any time within 24 hours, so it’s important to keep a close eye on your dog.

If your dog has only eaten a small amount of one of the non-toxic types of lilies, symptoms are usually mild, if there are any at all. An upset tummy—vomiting and diarrhea—is most common. Most dogs get better without the need for treatment, but if symptoms persist, then contact your veterinarian.

The main symptoms to look out for, if your dog has eaten toxic lilies, include vomiting, diarrhea, lethargy, loss of appetite (inappetence), abdominal pain, dehydration, change in the color of urine, seizures, arrhythmias (abnormal heart rhythm), excessive drooling, and redness of the gums, mouth, and eyes. If your dog shows any of these symptoms after eating lilies, you should contact your veterinarian straight away.

Remember that not all dogs display every symptom, and the severity of the poisoning depends on what type of lilies your dog ate and how many, as well as the size and breed of your dog. Smaller dogs are more susceptible, whereas larger dogs need to eat more lilies to become very sick.

My Dog Ate A Lily – What Should I Do?

So, your pup has eaten lilies. What do you do now?

  • Remove the plant material from your pet and put it out of their reach or in the trash
  • Check what type of lilies your dog has eaten and how much may have been ingested. It can be helpful to take a photo of the plant to show the veterinarian, allowing them to assess the poison risk better.
  • If your dog has eaten a non-toxic lily, then monitor him closely and contact your vet for advice
  • If your pet has eaten one of the poisonous types of lily plants, contact your veterinarian right away and get your dog checked out at the clinic. This is particularly important if they are already showing symptoms of lily poisoning such as vomiting, diarrhea, lethargy, inappetence, abdominal pain, dehydration, change in the color of urine, seizures, arrhythmias (abnormal heart rhythm), excessive drooling, or redness of the gums, mouth, and eyes.

Will My Dog Be Okay If He Ate A Lily?

Identify The Type Of Lily

If your pup has got his paws on some lilies, it’s important to determine what type of lily he has eaten. Identifying the plant, or taking a photo of it, can help your veterinarian assess the risk of poisoning and what treatment is necessary. Vets often contact specialist poison services who have extensive knowledge of different poisons in pets and can advise on the most suitable treatment.

If it has been less than two hours since your dog ate lilies, your vet may want to make him vomit so that he brings up all the plant material before it is digested. Your pup might also be prescribed some activated charcoal to prevent toxins from being absorbed from the gut.

Monitor For Symptoms

Mild tummy upsets are common after eating lilies and tend to clear up on their own without treatment. But if symptoms persist, your veterinarian can prescribe medication to make your pup feel better. If your pet is showing any symptoms of lily poisoning, then treatment is recommended and usually includes blood tests, IV fluid therapy to maintain hydration and support the liver and kidneys, as well as medication to prevent symptoms such as vomiting or seizures.


The prognosis for dogs that have eaten lilies depends on how severely they are affected. For mild tummy upsets or dogs who vomited quickly after eating lilies, it’s rare to experience further issues. However, in severe cases of lily poisoning, the prognosis may be more guarded depending on whether there is any organ damage. Deaths from lily poisoning in dogs are very rare.

How Do I Prevent My Dog From Eating Lilies?

How do you stop your pup from getting his paws on your plants?

Although many plants in our homes and gardens are safe for our pets, others, like lilies, can be harmful. So, it’s best not to encourage our furry friends to eat plant material as they cannot differentiate between the safe and poisonous ones.

You’re probably wondering why it is that your pup likes to eat your plants? Usually, this is a behavioral issue caused by boredom or lack of exercise. It can also be a great way of getting your attention. If your pup has a habit of tearing up your flower beds, it’s worth looking at his diet and exercise regime, and if you aren’t sure, then your veterinarian can help you here.

Calling your dog away from plants and rewarding him with a high-quality reward should help to reinforce positive behavior. Fencing off parts of the garden, especially when pups are young and exploring the world with their mouths, can be helpful too.
