Is Star Jasmine Poisonous to Dogs?

The ASPCA lists Star Jasmine (Trachelospermum jasminoides, also called Confederate Jasmine), family Apocynaceae, as Non-Toxic to Dogs, Cats, and Horses. The ASPCA per-plant page lists no toxic principles and no clinical signs for this species. It is not expected to cause poisoning if a dog nibbles it. Practical caveats: (1) Any plant eaten in quantity can cause mild, self-limiting gastrointestinal upset (vomiting, diarrhea, drooling) simply from indigestible plant fiber, so discourage browsing. (2) The cut vine/stem exudes a milky white sap that can be mildly irritating to skin; wash off any sap contact and avoid eye exposure. (3) Most important safety point is a NAMING/IDENTITY warning: 'jasmine' is a common name shared by several UNRELATED and genuinely TOXIC plants. True Star Jasmine (Trachelospermum jasminoides) is safe, but do NOT confuse it with: Carolina / Yellow Jessamine (Gelsemium sempervirens), which is highly toxic and can cause seizures, weakness, and respiratory depression; Night-blooming Jasmine / Jessamine (Cestrum nocturnum), which is toxic; or Madagascar Jasmine. Positively confirm the plant is Trachelospermum jasminoides before relying on this safe verdict. (4) Watch for fertilizers, pesticides, or systemic insecticides applied to garden plants, which can be harmful independent of the plant itself.

Is Star Jasmine poisonous to dogs?

No. The ASPCA lists Star Jasmine (Trachelospermum jasminoides) as non-toxic to dogs, as well as to cats and horses. A dog that nibbles the leaves or flowers is not expected to be poisoned, though eating a large amount of any plant can cause mild, temporary stomach upset.

My dog ate Star Jasmine leaves or flowers — should I worry?

A small nibble of true Star Jasmine is not considered poisonous per the ASPCA. The main risk is mild GI upset (vomiting or diarrhea) from the plant fiber, which usually resolves on its own. First make sure the plant is genuinely Trachelospermum jasminoides and not a toxic look-alike like Carolina jessamine (Gelsemium sempervirens). If your dog shows persistent vomiting, weakness, tremors, or other concerning signs, contact your vet or a poison helpline.

Is the white sap from Star Jasmine dangerous to dogs?

The cut stems release a milky white sap that can be mildly irritating to skin and is not classified as a poisoning hazard by the ASPCA. Rinse off any sap that contacts your dog's skin or mouth and keep it away from the eyes. There is no listed systemic toxicity.
