Are Cyclamen Poisonous to Dogs?
By Dr. Zubair Khalid, DVM, MS, PhD ·
Yes, cyclamen is poisonous to dogs. Every part of the plant contains toxic compounds, and the underground tuber (often called a bulb) holds the highest concentration [1]. If your dog chews or eats any part of a cyclamen, treat it as a poisoning risk and call for advice right away.

Quick Answer
- Cyclamen (Cyclamen spp.) is toxic to dogs, cats, and horses, and the toxic principle is terpenoid saponins [1].
- The tuber or bulb is the most dangerous part. Large ingestions of tubers can cause heart rhythm abnormalities, seizures, and death [1].
- Common early signs are drooling, vomiting, and diarrhea [1].
- Call your veterinarian, the ASPCA Animal Poison Control Center at (888) 426-4435, or Pet Poison Helpline at (855) 764-7661 for guidance.
- Do not induce vomiting unless a veterinarian tells you to.
Are Cyclamen Poisonous to Dogs?
Yes. The ASPCA Animal Poison Control Center lists cyclamen as toxic to dogs, cats, and horses [1]. The plant's scientific name is Cyclamen spp., and it belongs to the family Primulaceae [1]. You may also hear it called sowbread [1].
This matters because cyclamen is a popular indoor plant and a common gift. It shows up in grocery stores, florists, and garden centers, especially in fall and winter. Many owners do not know the plant is toxic until a dog starts drooling or vomiting near the pot.
If you keep other plants at home, it helps to know which ones carry risk. Our guide to common houseplants toxic to cats and dogs covers several species that are often kept indoors, and plants poisonous to dogs gives a broader list for your yard and garden.
Are Cyclamen Flowers Toxic to Dogs?
Yes. The flowers contain the same toxic saponins as the rest of the plant [1]. A single bloom may not carry much toxin, but any amount counts as an exposure. Dogs that grab a flower off a low table or sniff a bouquet can end up chewing the stem too.
Are Cyclamen Leaves Poisonous to Dogs?
Yes. The leaves are toxic as well [1]. Leaves are often the easiest part for a dog to reach because they sit close to the soil line. A dog that digs in the pot or pulls at the foliage is likely to swallow leaf material.
Are Cyclamen Bulbs Poisonous to Dogs?
Yes, and this is the part that worries veterinarians most. The tuber, which many people call a bulb, holds the highest concentration of toxin [1]. Dogs that dig up a potted cyclamen or root around in a garden bed can reach the tuber. Large ingestions of tubers are linked to the most severe outcomes, including heart rhythm abnormalities, seizures, and death [1].
Is Cyclamen Persicum Poisonous to Dogs?
Yes. Cyclamen persicum is one of the common species sold as a flowering houseplant, and it falls under Cyclamen spp., which the ASPCA lists as toxic to dogs [1]. The species name does not change the risk. Any cyclamen you bring home should be treated as toxic.
Is Cyclamen Dog Safe in Any Form?
No. There is no safe part of the plant for a dog to eat [1]. Dried plant material is still a concern, and so is water from a vase holding cut cyclamen stems. Keep pots, cut flowers, and garden clippings out of reach.
What Makes Cyclamen Toxic to Dogs?
The toxic principles in cyclamen are terpenoid saponins [1]. Saponins are natural plant compounds that foam when mixed with water, and they irritate the lining of the mouth and gut. That irritation is why drooling, vomiting, and diarrhea are the signs owners see first [1].
Saponins are also the reason the tuber is so dangerous. The tuber stores a much higher concentration of these compounds than the leaves or flowers [1]. When a dog eats a large amount of tuber, the toxin load can affect the heart and brain, which is why heart rhythm abnormalities and seizures are reported after large tuber ingestions [1].
Saponins from other plants have been studied in dogs. A safety study in healthy Beagle dogs looked at a triterpenoid saponin given by injection and measured how the body handled it over time [2]. That work involved a purified compound given under controlled conditions, not a houseplant, so it does not tell us the exact dose that harms a dog eating cyclamen. It does show that saponins are active compounds in dogs and that dose and route matter [2].
Signs of Cyclamen Poisoning in Dogs
The most common signs after a dog eats cyclamen are salivation, vomiting, and diarrhea [1]. Salivation often starts within minutes because the plant irritates the mouth. Vomiting and diarrhea tend to follow as the material moves through the stomach and intestines.
After a large ingestion of tubers, the picture can become much more serious. Reported signs include heart rhythm abnormalities, seizures, and death [1]. These are the cases that need emergency care without delay.
How Soon Do Signs Start?
Signs usually appear within a few hours of chewing or eating the plant. Drooling may be nearly immediate. Vomiting often starts within the first few hours. If your dog ate a tuber, watch closely for the first several hours and seek care even if your dog seems fine at first, because serious heart and brain signs can develop after a delay.
What Else Can Look Like Plant Poisoning?
Many toxins cause drooling, vomiting, and lethargy, so the signs alone do not confirm cyclamen. Other plant poisonings can cause similar gut signs. For example, a review of grayanotoxin poisoning from Ericaceae plants such as Rhododendron and Pieris japonica found that retching, regurgitation, and vomiting were common in affected animals [3]. Human medications are another frequent cause of poisoning in pets, and one report described a dog with lethargy, excessive salivation, poor appetite, dehydration, and neurologic abnormalities after being given a human pain medication [4]. This is why your veterinarian will ask what your dog could have eaten and may recommend testing.
What to Do Right Now If Your Dog Ate Cyclamen
Act quickly, but stay calm. The steps below apply whether your dog nibbled a leaf or dug up a whole tuber.
- Move your dog away from the plant and remove any plant material from the mouth if you can do so safely.
- Save the plant or a piece of it, or take a photo. Identification helps the veterinarian and the poison control team.
- Call your veterinarian, the ASPCA Animal Poison Control Center at (888) 426-4435, or Pet Poison Helpline at (855) 764-7661.
- Do not induce vomiting unless a veterinarian tells you to.
- Do not give food, milk, oil, or home remedies unless a veterinarian instructs you.
- Note the time of exposure and any signs you see, then follow the advice you are given.
Do not wait for signs to appear before you call. A dog that ate a tuber may look normal for a while and then worsen. Early advice can make a real difference.
If your dog is vomiting, drooling heavily, weak, wobbly, or having any kind of seizure activity, go to an emergency veterinary hospital now. Do not drive around looking for a clinic that is open. Call ahead so the team can prepare.
How Veterinarians Treat Cyclamen Poisoning in Dogs
Treatment depends on how much your dog ate, which part, and how your dog looks when you arrive. There is no antidote for cyclamen poisoning, so care focuses on removing toxin, controlling signs, and supporting the body.
Your veterinarian may start with a physical exam and questions about the exposure. If your dog ate the plant recently, the team may give medication to control vomiting and may use activated charcoal to bind remaining plant material in the gut. Whether decontamination is safe depends on your dog's condition, so this is a decision your veterinarian makes case by case.
If your dog is vomiting or has diarrhea, fluids and anti-nausea medication help replace losses and keep your dog comfortable. Blood work may be checked to look at organ values and electrolyte levels. If heart rhythm problems or seizures are present, your dog needs close monitoring and treatment for those specific problems [1].
The dose of any medication is calculated by your veterinarian from your dog's weight and health. Never give a human medication or leftover pet medication on your own, because some common drugs are toxic to dogs.

Outlook After a Dog Eats Cyclamen
Most dogs that eat a small amount of leaf or flower and receive prompt care do well. Drooling, vomiting, and diarrhea are unpleasant, but they usually improve with supportive treatment.
The outlook is more guarded after a large tuber ingestion. Heart rhythm abnormalities, seizures, and death have been reported in those cases [1]. This is why the amount and the plant part matter so much, and why a dog that ate a tuber needs urgent evaluation even if it seems fine at first.
Your veterinarian is the best judge of your dog's outlook. Follow the recheck plan and call if signs return or worsen.
Preventing Cyclamen Poisoning
Prevention is simple. Keep cyclamen out of reach, or do not keep it at all.
- Place cyclamen on a high shelf or in a room your dog cannot enter.
- Skip floor pots, low plant stands, and open garden beds where a dog can dig.
- Pick up fallen leaves, petals, and stems right away.
- Keep cut cyclamen out of vases your dog can reach.
- Put garden clippings in a closed bin, not on the ground.
- Teach family members and guests that the plant is toxic [1].
- If your dog is a chewer or digger, choose pet-safe plants instead.
If you are unsure whether a plant in your home is safe, check it before you bring it inside. Our article on what to do when your dog ate a toxic plant walks through the first steps, and it is a good page to bookmark.
Limitations and When to Contact a Veterinarian
This article gives general information. It cannot tell you how much toxin your dog ate or how your dog will respond. Individual cases need a veterinarian who can examine your dog and review the exposure.
Contact a veterinarian the same day if your dog chewed any part of a cyclamen, even if your dog seems normal. Call right away if you know or suspect your dog ate a tuber.
Go to an emergency hospital now if your dog is vomiting repeatedly, drooling heavily, weak, wobbly, collapsing, breathing oddly, or having seizure activity. Heart rhythm problems and seizures after large tuber ingestions are emergencies [1].
Schedule a routine visit if your dog had a minor exposure and your veterinarian advised home monitoring, or if signs linger after treatment. Keep the plant or a photo for identification, and write down the time of exposure.
Frequently Asked Questions
Is one bite of cyclamen dangerous to my dog?
A single bite is unlikely to be life threatening, but it can still cause drooling, vomiting, or diarrhea. Call your veterinarian or a poison control line for advice, because the answer depends on which part your dog bit and how much was swallowed.
Should I make my dog vomit after eating cyclamen?
No. Do not induce vomiting unless a veterinarian tells you to. Vomiting can be risky in some dogs, and the decision depends on your dog's condition and what was eaten.
Can my dog get sick from drinking vase water with cyclamen stems?
Yes, that water can contain plant compounds that leach from the cut stems. Pour it where your dog cannot reach it, and call for advice if your dog drinks it.
How long do cyclamen poisoning signs last in dogs?
Mild gut signs often improve within a day or two with supportive care, but timing varies with the amount eaten and the treatment given. Serious heart or brain signs need hospital care and can last longer.
Are there pet-safe plants I can keep instead of cyclamen?
Yes, many nontoxic houseplants exist, and swapping a toxic plant for a safe one removes the risk. Ask your veterinarian or check a trusted toxic plant list before you buy, and keep new plants out of reach until you confirm they are safe.
