Yes — yellow jasmine is severely toxic to dogs. Its gelsemine alkaloids cause progressive muscle weakness, breathing difficulty and seizures.

Also known as: Carolina Jasmine, Carolina Jessamine, Evening Trumpetflower, Gelsemium sempervirens · Gelsemium sempervirens

What makes it toxic

Gelsemine and related neurotoxic alkaloids in leaves, flowers, stems and roots. They interfere with nerve-muscle signaling, producing weakness that can end in respiratory paralysis.

Warning signs to watch for

Drooling, vomiting, stumbling weakness, drooping eyelids and dilated pupils, then tremors, seizures and labored breathing within a few hours.

What to do if your dog eats it

Get the dog to an emergency vet immediately with plant material for ID. Supportive care started early — respiratory monitoring, seizure control — is what carries dogs through.

Common questions

How toxic is one mouthful of the flowers?

Flowers carry real alkaloid load, and nectar concentrates it. Treat any confirmed chew of the vine as serious, not just the leaves.

Is it safe to grow on a fence dogs can reach?

No. Falling flowers and leaves accumulate where dogs sniff and chew, and the plant is dangerous in every part.
