Is Night-Blooming Jasmine Toxic to Dogs?
Also known as: Night Jasmine, Lady of the Night, Night Jessamine, Cestrum nocturnum · Cestrum nocturnum
What makes it toxic
Glycosides and alkaloids distributed through the plant and concentrated in the black berries. They irritate the digestive tract and can disturb nervous system function at higher doses.
Warning signs to watch for
Drooling, vomiting, diarrhea, excessive thirst and lethargy within hours. Significant ingestions can cause incoordination, tremors, elevated heart rate and fever.
What to do if your dog eats it
Remove any remaining plant material and call your vet the same day with an estimate of the amount. Tremors, stumbling or collapse is an immediate emergency.
Common questions
My dog ate fallen berries under the bush — what now?
Berries carry the highest toxin load, so treat it seriously: call your vet and watch for neurological signs, not just stomach upset.
Does the fragrance itself harm dogs?
No, the risk is ingestion. Some people find the nighttime scent overwhelming, but it is not a respiratory toxin for pets.
Is day-blooming cestrum different?
Same genus, same toxic compounds. All Cestrum species should be treated as hazardous to pets.
