Is Gladiola Toxic to Dogs?
Also known as: Gladiolus, Sword Lily, Corn Flag, Gladiolus spp. · Gladiolus spp.
What makes it toxic
Unidentified irritant toxins concentrated in the corm, causing gastrointestinal inflammation; leaves and flowers carry smaller amounts.
Warning signs to watch for
Drooling, vomiting, diarrhea, abdominal discomfort and lethargy within hours. Corm-eating dogs may show prolonged vomiting and need supportive care.
What to do if your dog eats it
Remove any plant material, offer water and call your vet — immediately if corms were eaten, since dogs frequently dig up bulbs. Vomiting that persists deserves veterinary attention in any case.
Common questions
How dangerous are gladiola corms compared to other bulbs?
Moderate — less dangerous than daffodil, tulip or autumn crocus bulbs, but a dog that eats corms still needs a vet conversation. Freshly planted bulbs are the highest-risk window.
My dog only ate one flower spike — watch or call?
A flower spike usually causes mild vomiting at most. Remove access, offer water and monitor; call the vet if vomiting repeats or the dog becomes dull.
Are gladiolas toxic in vase water too?
The stems leach mild irritants into vase water. Discourage dogs from drinking from flower vases — gladiola water would cause stomach upset.
