Are ficus houseplants poisonous to dogs?

Updated April 13, 2018

Rubber tree plants and weeping figs are just two of the house plants in the Ficus genus labelled with the everyday moniker of "Ficus." Growing as trees, shrubs and vines, these plants can pose a hazard to household dogs.


The American Society for the Prevention of Cruelty to Animals identifies plants in the Ficus genus as toxic to dogs. The plants contain two known toxins: ficin, a proteolytic enzyme and ficusin, a psoralen.


Ficus plants can cause itchy, swollen or red skin. Ingestion leads to irritation of the mouth, hypersalivation, nausea and vomiting. Lethal doses are dependent upon the individual animal. Vomiting, bloody faeces and lack of energy, mark a potentially lethal reaction to the ficin found in Ficus plants, according to the Journal of Pharmacology and Experimental Therapeutics.


Seek emergency veterinary medical care if you suspect your dog is suffering a reaction from eating a Ficus plant.
