Calla lilies poisonous to dogs

Just because a flower is beautiful doesn’t mean it’s safe for our furry friends. In fact, some of the prettiest spring flowers can be life-threatening to your pet if consumed.

“If your pet is having an allergic reaction to a poisonous plant, she’ll exhibit drooling, vomiting and tremors,” says Dr. Laurie Coger, DVM, CVCP, and owner of “She’ll get agitated and stressed as her body tries to cope with the toxin.”

Are Lilies Poisonous to Dogs?

One of the most-commonly planted spring flowers—lilies—are extremely toxic to cats; a compound in this beautiful flower triggers acute kidney failure in felines. And while scientific studies don’t show such a clear link between the lily flower and toxicity in dogs, consumption of the plant by canines certainly isn’t a good thing.

A toxin in lilies can trigger gastrointestinal upset in the first few hours after ingestion. Varieties such as Peace, Calla and Peruvian lilies aren’t as toxic as other varieties; however, you still want to keep your pet away. These lilies can irritate your pet’s mouth and esophagus. This irritation can trigger symptoms such as foaming and pawing at the mouth; in more severe cases, these lilies can cause digestive upset, including vomiting.

Other lily varieties are significantly more dangerous. True lilies, including those of the Lilium or Hemerocallis species, are more likely to trigger acute kidney failure in cats and potentially similar problems for dogs. Common names for these beautiful but deadly plants poisonous to dogs include Tiger, Day, Asiatic Hybrid, Easter, Japanese Show, Rubrum, Stargazer, Red, Western and Wood lilies. Lily of the Valley are also toxic plants for dogs; if your pet ingests this type of lily, she will experience potentially fatal heart arrhythmias.

So, to answer the question, “Are lilies poisonous to dogs?” Potentially—but while dogs may be at risk, even one or two leaves of a lily is enough to cause kidney failure in cats. The plant is so toxic to cats that just drinking the water from a vase of lilies can trigger kidney failure.

Signs of a Reaction

Lilies aren’t the only plant poisonous to dogs. Many commonly used outdoor landscaping plants and indoor decorative plants can be toxic to pets if consumed. It’s best to exercise caution and not let your pet consume any plants.

If your cat or dog is experiencing symptoms such as drooling, vomiting, gagging, a swollen and painful belly, lack of appetite, lethargy, diarrhea, or constipation and general unrest, he may have eaten something poisonous. Do not wait—go to the veterinarian immediately. If it’s late at night or on the weekend, you will need to go to a 24-hour emergency vet.

“When you go to the vet, bring the plant or at least take a picture of it with your phone,” says Dr. Coger. “If you have the exact scientific name, that’s even better. Your vet may need to contact animal poison control or other references for treatment advice.”

Dr. Coger says that treatment depends on the plant consumed. “If your pet comes in with an allergic reaction, we may need to induce vomiting,” she explains. “But other times, we’ll have to begin supportive care, such as increasing fluids, giving anti-nausea medications or prescribing activated charcoal or other medications to block toxin absorption.”

10 Flowers You May Not Know Are Toxic to Pets

  1. Daffodils

Toxic to: cats, dogs

Toxin: Lycorine (strong properties that induce vomiting); crystals on bulbs that cause severe tissue irritation as well.

Symptoms: Vomiting, nausea, diarrhea, drooling, abdominal pain. In severe cases can cause low blood pressure, abnormal breathing, convulsions and cardiac arrhythmias.

  1. Foxgloves

Toxic to: cats, dogs, humans

Toxin: Cardiac glycosides (affect the heart). All parts of the plant are considered toxic, including the water in the vase.

Symptoms: Vomiting, diarrhea, drooling, abnormal heart rate, cardiac arrhythmias, weakness, collapse, tremors or seizures, cardiac failure, death.

  1. Buttercups

Toxic to: cats, dogs, horses, cows

Toxin: Protoanemonin (irritates the mouth and GI tract). The flower part contains the most of this toxin.

Symptoms: Drooling, vomiting, diarrhea, not eating, blisters in the mouth, weakness, depression, bloody urine, walking like they are drunk. Serious side effects are not very common because the bitter taste and oral blisters usually stop animals from eating them.

  1. Lilies

Toxic to: cats

Toxin: Exact toxin is unknown.

Safe lilies: Not all species of lily are toxic. Safe lilies include peace lilies, Peruvian lilies and calla lilies (however calla lilies can cause irritation to the mouth and esophagus if ingested).

Dangerous lilies: Tiger lilies, day lilies, Asiatic hybrid, Easter lilies, Japanese show lilies, rubrum lilies, stargazer lilies, red lilies, western lilies and wood lilies. These are all highly toxic and even ingesting a few petals/leaves or pollen/vase water can cause rapid kidney failure in cats.

We all know that we need to keep our dogs away from the chocolate in our Easter baskets this week, but what about the Easter lilies in our holiday centerpieces? These popular flowers will make their appearance in many homes this season, so it’s important to ask—are Easter lilies poisonous to dogs?

Continue reading to discover if your spring flowers could pose a danger to your beloved pet.

Are Easter Lilies Poisonous to Dogs?

As you shop for holiday flowers this week, you may find yourself asking the question: “Are Easter lily plants poisonous to dogs?”

The short answer is NO. According to the ASPCA, Easter lilies are not poisonous to dogs.

Although they’re not lethal to dogs, Easter lilies can still cause intestinal discomfort if consumed in large quantities (like most things). Since a dog’s digestive system isn’t accustomed to processing large amounts of raw plant matter, your curious canine could experience an upset stomach, vomiting, or diarrhea.

If you have cats, however, steer clear: the Easter lily plant is highly toxic to felines. If ingested, even in small amounts, Easter lilies can cause kidney failure in cats, and ultimately death.

Even though Easter lilies are not poisonous to dogs, there are several important things to keep in mind.

  1. Your dog can still get sick from any chemicals you spray on your plants, such as insecticides, fungicides, or pesticides.
  2. According to the Missouri Botanical Garden, Easter lilies are susceptible to Botrytis fungi. This fungus causes food poisoning in humans and can make your dog very sick.
  3. If your dog really goes to town while munching on this plant, he could suffer from intestinal obstruction as plant matter builds up.

What To Do If Your Dog Eats An Easter Lily

If your dog consumes a few Easter lily petals this holiday, you don’t need to be concerned. If he was extra greedy, though, look out for some of these symptoms:

  • Vomiting
  • Diarrhea
  • Dehydration
  • Vocalization of pain
  • Lethargy

If your dog exhibits any of these symptoms, bring him to the vet for further examination. He may have inadvertently ingested harmful chemicals or a plant infected with the Botrytis fungi.
