Are Calla Lily Leaves Poisonous to Dogs? Signs, First Aid and Safe Placement

Your dog is sniffing at the potted calla lily by the window, and you notice a torn leaf with tooth marks on the edge. Many dog owners only ask “are calla lily leaves poisonous to dogs” after spotting damage like this.

The short version: Yes. The ASPCA lists calla lily (Zantedeschia aethiopica) as toxic to dogs because every part contains insoluble calcium oxalate crystals that irritate the mouth and stomach. Reactions are painful but usually not life-threatening, so a calm, quick response matters more than panic.

This guide covers the symptoms, first aid, vet care, safe placement indoors and other houseplants to keep out of reach.

Check These First

• Look inside your dog’s mouth for leaf fragments, redness or swelling on the gums, tongue or lips.
• Watch for heavy drooling, pawing at the face, head shaking or repeated lip licking.
• Check how much of the plant is missing, and whether the rhizome or flower was chewed too.
• Listen to your dog’s breathing. Any wheezing, gagging or labored breaths means a call to an emergency vet right now.
• Keep the plant, or a photo of it, nearby so you can identify it accurately on the phone.

Are Calla Lily Leaves Poisonous to Dogs?

Yes, calla lily leaves are poisonous to dogs, and so are the stems, flowers and rhizomes. The ASPCA lists the plant as toxic to dogs, cats and horses.

The toxicity comes from insoluble calcium oxalate crystals packed inside the plant tissue. These crystals are shaped like tiny needles, and they are held in special cells that burst when the leaf is crushed between teeth.

How the Crystals Cause Pain

When your dog bites a leaf, the crystals are released and embed in the soft tissue of the mouth and throat. The result is an immediate burning, stinging sensation, similar in effect to biting into something with fine splinters.

Because the pain starts right away, most dogs drop the leaf after one or two bites. That quick feedback is the main reason serious poisonings are uncommon.

Why Indoor Dogs Are at Higher Risk

Indoor calla lilies are often kept on low tables or floor-level plant stands near a sunny window, which puts them right at nose height for most dogs. A bored puppy during a long Chicago winter has plenty of time to investigate.

Moving the pot to a sturdy wall shelf or a tall plant stand at least 4 feet off the ground removes most of the risk. If you have a determined jumper, a baby gate across the doorway of a sunroom or spare room works well.

Is Every Calla Lily Variety Toxic?

All Zantedeschia species and hybrids contain calcium oxalate crystals. That includes the classic white form and the colorful pink, yellow, orange and near-black hybrids sold as gift plants.

Color, size and leaf spotting make no difference to safety. Treat every calla lily as toxic to dogs.

Which Parts of the Plant Are Most Dangerous?

Every part of the calla lily contains crystals, but the rhizome usually causes the strongest reaction because it is dense and holds a concentrated amount of plant tissue. Leaves and stems are the parts dogs chew most often.

Leaves and Stems

The broad, arrow-shaped leaves are soft and easy to tear. Dogs often grab a leaf that hangs over the rim of the pot, so leaves are the most common source of exposure.

Fallen leaves count too. If you are dealing with calla lily leaves turning yellow, pick up anything that drops to the floor, since a dying leaf still contains crystals.

Flowers

The trumpet-shaped spathe and the central spadix contain the same crystals as the leaves. Cut calla lilies in a vase are just as toxic as potted plants, and the vase water can hold plant sap.

Rhizomes and Soil

The underground rhizome is the part most likely to cause a strong reaction. Dogs that dig in pots can unearth it, and dormant rhizomes stored in a box over winter are a tempting chew toy.

Sophia’s tip: If you store calla lily rhizomes during dormancy, keep them in a lidded plastic bin on a closet shelf, not a paper bag on the floor. Label the bin so nobody else in the household opens it near the dog.

Signs Your Dog Chewed a Calla Lily

Symptoms usually start within minutes because the crystals cause instant irritation. Most signs focus on the mouth, then the stomach if any plant material was swallowed.

Symptom	Where it shows up	How serious
Heavy drooling	Mouth	Common, usually mild
Pawing at mouth or face	Mouth	Common, mild
Red or swollen lips, gums or tongue	Mouth	Moderate
Vomiting	Stomach	Common if swallowed
Difficulty swallowing	Throat	Moderate to serious
Loss of appetite	General	Mild to moderate
Hoarse bark or noisy breathing	Throat and airway	Serious, call a vet now

Mild Reactions

The most typical picture is a dog that suddenly starts drooling, licking its lips and rubbing its face on the carpet. Some dogs whine or shake their head.

These signs often ease within a few hours once the plant is removed and the mouth is rinsed. Your dog may refuse food or treats until the soreness fades.

Stomach Upset

If your dog swallowed pieces of leaf or rhizome, vomiting and sometimes diarrhea can follow. Small amounts of chewed leaf usually pass with only brief stomach upset.

Repeated vomiting can lead to dehydration, especially in small breeds and puppies. That is a reason to contact your vet rather than wait it out.

Warning Signs That Need Emergency Care

Swelling in the throat is uncommon, but it can narrow the airway. Watch for gagging, wheezing, a change in bark, labored breathing or a refusal to drink water.

Any of these signs means you should go to an emergency vet immediately. Do not wait to see if it improves on its own.

What To Do in the First 30 Minutes

Remove any remaining plant material, rinse your dog’s mouth gently and call your vet or an animal poison control line. Quick, calm steps keep a mild exposure from getting worse.

Step 1: Clear the Mouth

Move your dog away from the plant and take out any leaf pieces you can see. Use your fingers carefully, or wrap a damp cloth around a finger and wipe the gums and inside of the cheeks.

Wear gloves if you have them. The sap and crystals can irritate your own skin as well.

Step 2: Rinse and Soothe

Let your dog drink fresh water, or gently flush the mouth with a small stream of lukewarm water while keeping the head tilted down so water drains out. Never force water down the throat.

Many vets suggest offering a small amount of plain milk or plain yogurt, which can help ease the burning. Ask your vet first if your dog has a sensitive stomach or dairy intolerance.

Step 3: Call for Advice

Call your regular vet, an emergency clinic or the ASPCA Animal Poison Control Center at (888) 426-4435. A consultation fee may apply, and it is available around the clock.

Have this information ready:

• Your dog’s weight, age and breed
• Which part of the plant was eaten and roughly how much
• When the exposure happened
• Every symptom you have seen so far

What Not To Do

Do not induce vomiting unless a vet tells you to. Bringing irritating plant material back up can cause more damage to the throat and mouth.

Avoid home remedies like hydrogen peroxide, salt water or activated charcoal without professional guidance. These can create new problems on top of the original irritation.

Sophia’s tip: Save the ASPCA poison control number and your nearest 24-hour vet as contacts in your phone today. Tape the same numbers inside a kitchen cabinet so a sitter or dog walker can find them fast.

What Happens at the Vet?

Most dogs with calla lily exposure receive supportive care focused on pain and irritation. Your vet will examine the mouth, check breathing and decide whether medication or fluids are needed.

The Exam

The vet will look for swelling in the mouth and throat and listen to your dog’s breathing. Bringing the plant, a leaf sample or a clear photo helps confirm the identification.

Bloodwork is usually not needed for simple mouth irritation. It may be recommended if vomiting was heavy or your dog has other health conditions.

Common Treatments

Treatment depends on the severity of the reaction. Typical options include:

• Rinsing the mouth more thoroughly
• Anti-inflammatory or pain medication
• An antihistamine to reduce swelling
• Anti-nausea medication if vomiting continues
• Intravenous or under-the-skin fluids for dehydration

Dogs with airway swelling may need to stay for observation until breathing is normal again.

Recovery at Home

Most dogs recover within 12 to 24 hours. Offer soft food, plenty of fresh water and a quiet place to rest.

Call your vet again if your dog stops eating for more than a day, keeps vomiting or shows any new breathing trouble.

How To Keep Calla Lilies and Dogs in the Same Apartment

You can keep a calla lily with a dog if the plant stays fully out of reach and you clean up fallen debris. Some households with puppies or chewers do better skipping the plant for a few years.

Choose the Right Spot

Calla lilies want bright, indirect light, so an east-facing window or a spot 2 to 4 feet back from a south or west window works well. Place the pot on a high shelf or plant stand in that light.

Keep the plant away from radiators and forced-air vents. Dry, hot air stresses the leaves, and stressed plants drop more leaves onto the floor where a dog can reach them.

Manage Leaves and Flowers

Trim yellowing leaves and spent flowers before they fall. Use clean scissors and wrap the cuttings in a bag before putting them in a lidded trash can.

A plant that looks like it is fading still needs the same care around pets. If your calla lily is dying, clean up the soft, collapsing stems quickly, since dogs are often drawn to the smell of decaying plant matter.

Repotting and Dormancy

Repotting exposes the rhizome, so do it on a counter or balcony with the dog in another room. When you transplant a calla lily, sweep up every crumb of soil and broken root before letting your dog back in.

During dormancy, the pot may look like an empty container of soil. Dogs that like to dig can still reach the rhizome, so keep dormant pots up high or covered.

Sophia’s tip: Top the soil with a layer of coarse decorative stones about 1 inch deep. It discourages digging and keeps curious noses away from the rhizome without blocking water.

Train a Leave-It Cue

A solid “leave it” command helps with every toxic plant, not just calla lilies. Practice with treats and reward your dog for turning away from plants.

Training is a backup, not a replacement for placement. A dog left alone for eight hours will not always remember the rule.

Do Bloom Problems Change the Risk?

No. A plant with calla lily leaves but no flowers is still fully toxic, since the leaves carry the same crystals as the blooms. Treat a leafy, non-flowering plant with the same caution.

Calla Lily vs True Lilies: Why the Difference Matters

Calla lilies are not true lilies. They belong to the arum family, while true lilies belong to the genus Lilium, and the difference changes how serious a poisoning can be.

Calla Lilies and Peace Lilies

Calla lilies and peace lilies both contain insoluble calcium oxalate crystals. In dogs and cats, they cause mouth pain, drooling and stomach upset, but they do not cause kidney failure.

True Lilies and Daylilies

Easter lilies, tiger lilies, Asiatic lilies, Oriental lilies and daylilies are extremely dangerous to cats. Even pollen or vase water can cause kidney failure in cats.

In dogs, true lilies and daylilies usually cause milder stomach upset rather than kidney failure. Even so, any lily exposure deserves a call to your vet.

Plant	Plant family	Main concern for dogs	Main concern for cats
Calla lily	Arum family	Mouth irritation, vomiting	Mouth irritation, vomiting
Peace lily	Arum family	Mouth irritation, vomiting	Mouth irritation, vomiting
Easter, tiger, Asiatic lily	Lilium	Mild stomach upset	Kidney failure, emergency
Daylily	Hemerocallis	Mild stomach upset	Kidney failure, emergency

If You Have Cats Too

Households with both dogs and cats should identify every “lily” by its full name. A bouquet labeled simply as lilies may contain a dangerous true lily, even if the calla lily in the window is a lower-risk plant for your cat.

People are affected too. If you have young children, read about whether a calla lily is poisonous to humans, since the same crystals can irritate a child’s mouth.

Other Common Houseplants To Keep Away From Dogs

Many popular indoor plants contain the same calcium oxalate crystals as calla lilies, and a few carry more serious toxins. Check every plant against the ASPCA list before bringing it home.

Plants With Calcium Oxalate Crystals

These plants cause reactions similar to calla lilies:

• Pothos
• Philodendron
• Dieffenbachia (dumb cane)
• Monstera
• Peace lily
• ZZ plant
• Alocasia and Colocasia (elephant ears)

Plants With More Serious Toxins

Some plants cause effects beyond mouth irritation and need urgent vet attention:

• Sago palm, which can cause liver failure and is often fatal
• Aloe vera, which causes vomiting and diarrhea
• Jade plant, which causes vomiting and lethargy
• Snake plant, which causes nausea and vomiting
• Cyclamen, especially the tuber, which causes heavy vomiting

Dog-Friendly Alternatives

If you want greenery at floor level, the ASPCA lists several common houseplants as non-toxic to dogs:

• Spider plant
• Boston fern
• Parlor palm
• Calathea and prayer plant
• African violet
• Cast iron plant

These still should not be eaten in large amounts, since any plant material can upset a dog’s stomach.

Your Next Steps

• Move your calla lily to a high shelf or tall stand at least 4 feet off the floor in bright, indirect light.
• Save the ASPCA Animal Poison Control number, (888) 426-4435, and your nearest 24-hour vet in your phone.
• Check the pot daily for yellow leaves and spent flowers, and remove them before they drop.
• Store dormant rhizomes in a closed, labeled bin out of reach.
• Look up every other plant in your home on the ASPCA toxic plant list.
• Practice a “leave it” cue with your dog using plants as the target.
