What this means for your dog
Dogs digging in the garden are the classic Butterfly Iris case — the toxic terpenoids are concentrated in the rhizomes (the bulb-like underground stems), and dogs are happy to unearth and chew them. ASPCA lists it as toxic to dogs; expect drooling, vomiting, and diarrhea. Pet Poison Helpline notes iris poisoning is rarely fatal but can cause significant GI tract irritation.
What to watch for
Most common: drooling, vomiting, and diarrhea, often with abdominal discomfort and lethargy. Severity scales with how much rhizome was eaten. With larger ingestions Pet Poison Helpline warns of more pronounced GI damage, prolonged loss of appetite, and dehydration. If your dog touched cut sap, watch for skin or eye irritation as well.
Time window
Signs can appear as soon as 2 hours after ingestion. Mild cases typically resolve in 24–48 hours with fluids and a bland diet; rhizome ingestions can produce GI signs that linger several days and may need IV support.
When to call the vet
Call your vet or Pet Poison Helpline (855-764-7661) for any vomiting or diarrhea after a Butterfly Iris ingestion. Call immediately if you saw your dog dig up and chew the rhizome, if vomiting is repeated, or if you see signs of dehydration (lethargy, dry gums, sunken eyes). Small dogs and puppies should be evaluated even after small ingestions.
First aid at home
Stay calm, take any plant pieces out of your dog's mouth and off the fur, and remove access to the plant so there's no repeat. If there's sap on the eyes, mouth, or skin, flush the area with water. Do not induce vomiting unless your vet or poison control specifically tells you to, and don't give over-the-counter medication. Call your vet or Pet Poison Helpline before driving in so they can plan treatment.

Is the rhizome of Butterfly Iris more dangerous than the leaves?

Small dogs and puppies should be evaluated even after small ingestions.
