Yes, hyacinths are toxic to dogs. Bulbs carry the highest toxin load and cause severe vomiting; a dug-up hyacinth is a genuine emergency candidate.

Also known as: Garden Hyacinth, Common Hyacinth, Dutch Hyacinth · Hyacinthus orientalis

What makes it toxic

Concentrated allergenic lactones and oxalate crystals in bulb scales, with lower levels in flowers and stems. They irritate the GI tract strongly.

Warning signs to watch for

Profuse drooling, vomiting, diarrhea and abdominal pain within hours of eating bulb material; larger exposures add tremors and depression.

What to do if your dog eats it

Call your vet promptly after any bulb ingestion — dogs digging up fall-planted bulbs is the classic case. Bring the bulb; decontamination and fluids usually prevent serious illness.

Common questions

My dog dug up hyacinth bulbs in fall — how bad?

Potentially quite bad — stored and planted bulbs are the most concentrated part. A same-day vet call is the right move even if symptoms have not started.

Are hyacinths worse than tulips for dogs?

Similar. Both belong to the same family and carry tulipalin-type lactones, highest in the bulbs. Treat them identically.

Is touching hyacinth bulbs harmful to the dog?

The sap can irritate skin and mouth, but real poisoning requires chewing or swallowing. Store bulbs where the dog cannot reach.
