Toxic Plants For Dogs & Other Pets: 

A surprisingly large number of common garden and household plants are toxic to pets, and reactions to toxicity range from mild to life-threatening. Pets, like young children, explore the world with their senses, and they are therefore vulnerable to accidental poisoning.  Many of these plants make wonderful additions to the  garden, but it is important to know which plants are toxic.  If possible, avoid planting these where pets (or children) will have frequent unsupervised access to the plants. 

The 12 plants listed below are responsible for the majority of calls about possible plant poisoning. 
The toxicity of the plants below varies according to the species of animal exposed (cat, dog, bird, etc.), the amount of the plant that was ingested, and  the specific variety or species of the plant. 

If you suspect your pet has ingested any of the plants below, call your veterinarian immediately.  Do not wait to see if symptoms appear, because in some cases of poisoning, by the time symptoms appear it is too late to save the animal.

  1. Lilies : Ingesting any part of the plant can cause complete kidney failure in 36-72 hours. First symptoms appear in a few hours and may include appetite suppression, lethargy, vomiting.  Cats are especially sensitive to lily poisoning, so be very careful to keep your cats away from liliies of any kind, including the Amaryllis, Easter lilies, and Stargazer lilies so often found in homes around the holidays.
  2. Lily of the Valley : Ingesting any part of the plant can cause cardiac dysrhythmias, vomiting, diarrhea, confusion, weakness, and even death. (Photo courtesy of freebigpictures.com web site).
  3. Anemone (Anenome and Pulsatilla, family): Irritating to the mucus membranes, and can cause blisters, hemorrhagic gastritis, shock, convulsions, and death. (Photo is Japanese Anemone).
  4. Aloe Vera : Vomiting, depression, diarrhea, anorexia, tremors, change in urine color.
  5. Amaryllis : All species, including Belladonna Lily, are toxic, and especially dangerous to cats. The bulbs are the toxic part of the plant.  The "Amaryllis" commonly seen during the December holidays are Hippeastrum species.  Symptoms include vomiting, depression, diarrhea, abdominal pain, hyper-salivation, anorexia, tremors.  (Photo courtesy of Ellen Zagory, UC Davis Arboretum).
  6. Asparagus Fern : Allergic dermatitis, gastric upset, vomiting, diarrhea.
  7. Daffodil : Vomiting, diarrhea. Large ingestions cause convulsions, low blood pressure, tremors, cardiac arrhythmias.
  8. Philodendrons: Irritation, intense burning and irritation of the mouth, lips, tongue, excessive drooling, vomiting, difficulty swallowing.
  9. Jade Plants : Vomiting, depressions, ataxia, slow heart rate.
  10. Chrysanthemums: Vomiting, diarrhea, hyper salivation, incoordination, dermatitis.
  11. Cyclamen : The tubers or rhizomes contain the toxic glycoside cyclanin, a terpenoid saponin.  Ingestion can cause excess salivation, vomiting, diarrhea, heart rhythm abnormalities, seizures, or even death in rare cases.
  12. Cycads (including Sago palm; cardboard palm; etc.): The "Sago palm" is a cycad, not a true palm, and all parts of the plant are poisonous. Symptoms include vomiting, lethargy, melena (black "tarry" feces), icterus (jaundice), increased thirst, hemorrhagic gastritis, bruising, coagulopathy, liver failure, and death.  A northern California police dog died after ingesting parts of this plant.
