What this means for your dog

Dogs are most often poisoned by hyacinth when they dig up and chew the bulbs — the outer bulb layer holds tissue-irritating crystals plus alkaloids that cause profuse drooling, vomiting, and diarrhea. Leaves and petals are less concentrated but still cause GI upset. A large bulb ingestion in a small dog can become a real emergency.

What to watch for

Most common: heavy drooling, vomiting, and diarrhea, sometimes with blood. With larger ingestions watch for elevated heart rate, faster or labored breathing, and abdominal pain. Bulb fragments occasionally cause foreign-body obstruction — a dog that keeps trying to vomit but can't bring anything up needs to be seen.

Time window

Onset within 1–2 hours of ingestion. Most uncomplicated cases resolve in 24–48 hours with supportive care (anti-nausea medication, fluids, mouth rinsing). Bulb ingestions and large doses can extend the recovery window.

When to call the vet

Call immediately if your dog ingested a whole bulb, or if you see persistent vomiting, blood in vomit/stool, fast breathing, or signs of an obstruction (repeated retching, painful belly). For a small leaf or petal nibble with mild drooling that resolves quickly, monitor at home and call your vet or the ASPCA Animal Poison Control Center (888-426-4435) for guidance.

First aid at home

Take any remaining plant or bulb pieces away from your dog and rinse the mouth with water if your dog will allow it. Do not induce vomiting at home unless a veterinarian or the ASPCA Animal Poison Control Center tells you to — bulb material can re-irritate the throat coming back up. Call (888) 426-4435 or your vet before giving any medication.
