Dogs that grab an iris leaf or, more concerning, unearth a rhizome usually get GI upset rather than systemic illness. The toxic principles are pentacyclic terpenoids (zeorin, missourin, missouriensin), most concentrated in the rhizome. ASPCA classifies iris as toxic to dogs but not life-threatening — most cases resolve with at-home supportive care.
Most common: heavy drooling and salivation, vomiting, diarrhea, and a tucked-up posture from abdominal pain. Lethargy is common for the first day. Bloody vomit or stool is uncommon and bumps urgency up.
Onset within 1–3 hours of ingestion. ASPCA does not publish a precise duration; uncomplicated GI cases generally resolve in 24 hours with supportive care.
Call your vet the same day if your dog ate a rhizome (the high-dose exposure), if vomiting goes past two episodes, or if you see blood, severe abdominal pain, or refusal to drink. For a leaf nibble with one drool-and-spit episode and otherwise normal behavior, monitor for 24 hours. Call the ASPCA Animal Poison Control Center (888-426-4435) any time you want a triage opinion.
Remove any plant pieces still in your dog's mouth and clear the area so he can't keep grazing. Offer fresh water. Do not induce vomiting unless your veterinarian or the ASPCA Animal Poison Control Center tells you to — irritant plant material can be worse coming back up. Call (888) 426-4435 or your vet before giving anything by mouth.
