Pet ingestion lookup
My dog ate Gladiola - what should I do?
Gladiolus species
Potentially toxic
Contact your veterinarian or an animal poison-control resource now, especially if any amount was chewed or swallowed.
Verified against ASPCA/provenance audit 2026-05-06 on May 6, 2026.
Signs to watch for
Drooling, vomiting, diarrhea, and general malaise.
Escalation note
The corm (bulb) is the most toxic part of the plant. If your dog ingests any portion of a Gladiolus, contact your veterinarian immediately for guidance.
What to watch for
Drooling, vomiting, and diarrhea are most common, followed by lethargy. After bulb ingestion specifically, watch for weakness or an irregular heartbeat.
Time window
ASPCA does not publish onset or duration; GI signs typically begin within hours of ingestion.
When to call the vet
Call your vet or ASPCA Poison Control if vomiting is persistent, your dog seems weak, or you know an entire bulb was eaten — bulb ingestion warrants immediate contact.
What this means for your dog
Dogs are inclined to dig up and crunch Gladiola corms, which carry the most concentrated dose of toxin. ASPCA flags it as toxic; in most cases that means GI upset, but eating a whole corm can occasionally trigger more serious systemic signs.
