List of Toxic Plants for Dogs

Dealing with a dog that has been poisoned by a plant can be a scary situation. Who do I call? What do I do? How could I have prevented this? To help you on that last one, here is a list of some of the most common poisonous plants to dogs.

1. Autumn Crocus

The Autumn Crocus can cause an intense burning sensation in the mouth, vomiting, diarrhea, seizures, liver and kidney damage, and even heart arrhythmias. Although the entire plant is considered toxic to dogs, the toxicity is highest in the bulbs of the plant.

2. Azalea

Ingestion of just a few leaves of Azaleas can cause oral irritation with subsequent vomiting and diarrhea in dogs. In severe cases, ingestion can cause a drop in blood pressure, coma, and even death.

3. Daffodil

Although the entire plant is considered poisonous to dogs, it is the Daffodil bulb that is the most toxic. Ingestion of any portion of a Daffodil can cause vomiting, diarrhea, abdominal pain, arrhythmias, convulsions, and a serious drop in blood pressure.

4. Dieffenbachia

Dieffenbachia, also known as Dumb Cane, is a common houseplant that can cause oral irritation, vomiting, and difficulty swallowing in dogs. It can also create a burning sensation of the lips, tongue, and mouth.

5. Tulip

Although the entire plant of a tulip is considered toxic, it is the bulb that is the most poisonous to dogs. Ingestion can cause significant oral irritation, excessive drooling and nausea.

6. Kalanchoe

Also known as the Mother-In-Law plant, the Kalanchoe is a common house plant with small dense flowers. When ingested it can cause vomiting and diarrhea. In rare cases, heart arrhythmias can occur from a poisoning.

7. Sago Palm

The Sago Palm is an extremely poisonous plant to dogs when ingested, causing bloody vomiting and diarrhea, bleeding disorders, liver failure and death.

8. Oleander

Oleander is a popular ornamental flowering shrub commonly found in the southern United States and California. Its cardiac glycosides, similar to digoxin, are very toxic to dogs and can cause fatal heart abnormalities, muscle tremors, incoordination, vomiting and bloody diarrhea.

9. Cyclamen

Also known as Sowbread, the Cyclamen is a common household flowering plant with poisonous properties (i.e., terpenoids) to dogs. It can cause oral irritation, vomiting, diarrhea, heart abnormalities, seizures and death.

10. Amaryllis

Especially popular around Easter, the lovely Amaryllis is also poisonous to dogs. Its toxins can cause vomiting, depression, diarrhea, abdominal pain, hypersalivation, anorexia, and tremors in dogs.

    PLEASE get the photos and captions correct. the photo you have as Dieffenbachia is actually a Hosta which is a hardy perennial . Sago palm is not the same plant as a Coontie fern (not palm) or a Cardboard palm. Sago and Coontie (which grows in florida naturally) are Cycads with sago being a common houseplant where it is not hardy. Cardboard palm is a Zamia NOT NOT NOT a sago at all. with the photos now people will be ripping out their Hosta thinking it's a Dieffenbachia
