Safety status
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.

Questions about Hyacinth
Are hyacinths toxic to dogs?
Yes, hyacinths (Hyacinthus orientalis) are toxic to dogs. The plant contains calcium oxalate crystals and alkaloids that irritate the mouth and gastrointestinal tract, causing drooling, vomiting, and diarrhea. The bulb is the most dangerous part — ingesting it can cause more severe GI distress than chewing on leaves or petals.
What symptoms will my dog show after eating a hyacinth?
The most common signs are heavy drooling, vomiting, and diarrhea, sometimes with blood. With larger ingestions — especially of the bulb — watch for elevated heart rate, labored breathing, and abdominal pain. Symptoms typically appear within 1–2 hours of ingestion.
What should I do if my dog ate a hyacinth bulb?
Remove any remaining plant or bulb pieces and rinse your dog's mouth with water if they'll allow it. Do not induce vomiting at home — bulb material can re-irritate the throat on the way back up. Call the ASPCA Animal Poison Control Center at (888) 426-4435 or your vet immediately for guidance before giving any medication.
When is hyacinth poisoning in dogs serious enough to go to the vet?
Call your vet immediately if your dog swallowed a whole bulb, or if you see persistent vomiting, blood in the vomit or stool, fast or labored breathing, or signs of an obstruction (repeated retching with nothing coming up and a painful belly). A small nibble of leaf or petal with mild drooling that clears up quickly can be monitored at home, but still call (888) 426-4435 for guidance. Most uncomplicated cases resolve within 24–48 hours with supportive care.
