11 Common Houseplants Poisonous to Dogs: What Every Pet Owner Should Know
Houseplants bring vibrant color and fresh air into our living spaces, but some of the most popular indoor varieties can pose serious dangers to our canine friends. As a responsible dog owner, understanding which houseplants are toxic and how to keep your pet safe is essential for a healthy, happy home.
Why Some Houseplants Are Harmful to Dogs
Dogs are curious animals who often explore their environment by sniffing, chewing, or licking. If ingested, certain houseplants can cause symptoms ranging from mild digestive upset to life-threatening complications. Toxic compounds can be present in leaves, stems, flowers, berries, or saps, making it crucial to recognize which plants are best kept out of reachâor out of your home altogether.
Top 11 Houseplants That Are Poisonous to Dogs
Below are 11 common household plants known to be toxic to dogs. While severity may vary depending on the plant and the amount ingested, it is advisable to avoid these varieties if you share your home with a furry companion.
- Sago Palm (Cycas revoluta) â All parts are highly poisonous, especially the seeds. Ingestion can cause vomiting, diarrhea, seizures, liver failure, and even death.
- Dieffenbachia (Dumb Cane) â Chewing the leaves releases insoluble calcium oxalate crystals, causing severe mouth irritation, drooling, vomiting, swelling, and difficulty swallowing.
- Peace Lily (Spathiphyllum) â Contains oxalates and can lead to oral irritation, excessive drooling, vomiting, and difficulty swallowing when chewed or eaten.
- Philodendron â Like many members of the Araceae family, philodendrons contain insoluble oxalates, causing irritation of the mouth, throat, and digestive tract, as well as vomiting and drooling.
- Pothos (Devilâs Ivy) â This popular, hardy plant is also a member of the Araceae family. Its ingestion causes major oral irritation, vomiting, and possible swelling of the upper airway.
- Aloe Vera â While prized for its skin-soothing gel, aloe contains saponins and anthraquinones, which can trigger vomiting, diarrhea, loss of appetite, or tremors in dogs.
- Caladium (Elephant Ear) â Gorgeous but dangerous, caladiumâs oxalate crystals irritate the mouth and gastrointestinal tract, causing intense burning, drooling, difficulty swallowing, and vomiting.
- Cyclamen â All parts are toxic, but especially the tubers (roots). Ingestion leads to intense gastrointestinal distress and, in large amounts, abnormal heart rhythms and possibly death.
- Poinsettia â Although not as deadly as some believe, this winter favorite can still cause mild vomiting, drooling, and diarrhea if your dog decides to take a bite.
- Schefflera (Umbrella Plant) â Schefflera contains insoluble calcium oxalate crystals. Chewing leads to oral irritation, drooling, vomiting, and swelling of the mouth or throat.
- Desert Rose (Adenium obesum) â All parts are toxic. These contain cardiac glycosides, which can lead to vomiting, diarrhea, abnormal heart rate, and collapse.
Symptoms of Plant Toxicity in Dogs
If your dog has ingested a poisonous plant, symptoms often appear within minutes to a few hours. Knowing what to look for can make the difference in seeking prompt veterinary care:
- Excessive drooling
- Vomiting and/or diarrhea
- Loss of appetite
- Oral or facial swelling
- Pawing at the mouth or face
- Lethargy or weakness
- Difficulty breathing or swallowing
- Seizures or abnormal heart rhythms (with certain toxins)
If you observe any combination of these signs and suspect plant ingestion, contact your veterinarian or an animal poison control center immediately.
Safer Alternatives: Pet-Friendly Houseplants
You donât have to sacrifice greenery for your dog’s safety. Consider replacing toxic plants with these pet-safe varieties:
- Spider Plant (Chlorophytum comosum)
- Boston Fern (Nephrolepis exaltata)
- Bamboo Palm (Chamaedorea seifrizii)
- Areca Palm (Dypsis lutescens)
- Orchid (Orchidaceae)
- Peperomia (Peperomia spp.)
Not only do these options add lush beauty and purify the air, but they do so without posing a threat to your canine companion.

What to Do If Your Dog Eats a Toxic Plant
Speed is critical if your dog ingests a poisonous houseplant. Hereâs how to respond:

- Place plants out of reach: Place plants on high shelves, hang them from the ceiling, or use room dividers to restrict access.

Frequently Asked Questions (FAQs)
Q: Are all parts of these plants toxic to dogs?
Many poisonous houseplants contain toxins throughout the plant, but often the highest concentration is found in specific parts, such as seeds (sago palm), tubers (cyclamen), or leaves (dieffenbachia). Always assume the whole plant poses a risk unless verified otherwise by a professional.
Q: Is touching a toxic houseplant dangerous for dogs?
Most plants require ingestion to cause serious illness in dogs, but in some cases, sap or pollen on the skin or fur may cause localized irritation or lead to secondary ingestion when the dog grooms itself.
Q: How can I pet-proof my houseplants?
- Choose only non-toxic, dog-safe plants for indoor use.
- Keep higher-risk plants in rooms inaccessible to your dog or elevated out of reach.
- Monitor your dog for signs of interest in chewing household plants, especially puppies.
- Train “leave it” and provide distractions like safe chew toys.
Q: What should I bring to the vet if my dog eats a plant?
If possible, bring a piece of the plant or a photo for identification. Be ready to share details about when exposure occurred and any symptoms observed.
