What makes it toxic

No established toxin is documented in Muscari for dogs, though bulb tissue generally carries irritants that upset the stomach.

Warning signs to watch for

Possible drooling, vomiting or loose stools after eating bulbs or, less commonly, leaves.

What to do if your dog eats it

Offer water and monitor for a day. Call your vet if vomiting recurs, especially after a bulb feast — the plant matter itself plus gut irritation is the concern.

Common questions

Are grape hyacinth bulbs like tulip bulbs for dogs?

Milder, most likely. Tulip and hyacinth bulbs carry concentrated allergenic lactones; Muscari is not documented as seriously toxic, but bulbs still irritate.

Should I stop planting them in my yard?

If your dog digs, either fence the bed or choose pet-safer bulbs. Otherwise grape hyacinth is considered a low-risk spring flower.
