Is sago palm toxic to dogs?

Sago palm contains a toxin that primarily affects the liver, and unlike plants where risk scales gradually with amount eaten, sago palm can cause serious harm from a genuinely small quantity, particularly the seeds. This places it firmly in the same urgent category as oleander and foxglove rather than the milder irritant category many other garden plants fall into.

Sago palm is popular as an ornamental plant in warmer climates and increasingly sold as a decorative container or houseplant further north, meaning exposure is not limited to outdoor gardens in tropical regions. The seeds, sometimes called nuts, are the most commonly ingested part, often falling to the ground where a curious dog can find and chew them.

Vomiting, diarrhea, lethargy, and signs of liver distress such as yellowing of the gums or eyes can appear within hours to a couple of days after ingestion, sometimes progressing seriously if untreated. Because the delay before symptoms fully develop can be longer than with some other toxic plants, do not wait for visible illness before seeking help if ingestion is known or suspected.

If you own a sago palm, whether as a garden plant or an indoor container specimen, keep it entirely out of reach, fenced off outdoors or on a high shelf indoors, and clean up fallen seeds and fronds promptly rather than allowing them to accumulate on the ground where a dog might find them.
