Safety status
What this means for your dog
Dogs: ASPCA lists Sand Lily as non-toxic to dogs. The common name is misleading — this prairie wildflower is Leucocrinum montanum, not a true Lilium, and is not associated with the dog-specific GI reactions that some true lilies and lookalikes cause.
What to watch for
ASPCA reports no toxic principle, so no specific symptoms are expected. A dog that grazed leaves or dug at the corm-like roots may have a transient stomach upset purely from the plant fiber — one bout of vomiting or soft stool, then back to normal.
Time window
Onset and duration are not documented because the plant is non-toxic. Any mechanical GI upset from plant fiber would typically resolve within 24 hours.
When to call the vet
Call your vet if vomiting or diarrhea continues past one episode, if your dog seems lethargic for more than a few hours, or if a large quantity was consumed and you're unsure of the identification.

Questions about Sand Lily
Is Sand Lily toxic to dogs?
Sand Lily (Leucocrinum montanum) is considered non-toxic to dogs — the ASPCA reports no toxic principle in this plant. That said, the classification is currently under review pending curator verification, so if your dog ate a significant amount, it's reasonable to monitor them closely.
What happens if a dog eats Sand Lily?
No specific toxic symptoms are expected because the plant has no documented toxic principle. A dog that grazed the leaves or dug at the roots may experience a brief, mild stomach upset — one episode of vomiting or soft stool from the plant fiber — which typically resolves within 24 hours.
What should I do if my dog ate Sand Lily?
Monitor your dog for any signs of stomach upset. Call your vet if vomiting or diarrhea continues past one episode, if your dog seems lethargic for more than a few hours, or if a large quantity was consumed and you're unsure of the plant's identity. You can also reach the ASPCA Animal Poison Control Center at (888) 426-4435.
Can the roots or corms of Sand Lily cause problems for dogs?
No toxic compounds are documented in any part of the Sand Lily, including the fleshy, corm-like roots. A dog that digs and chews the roots may get more plant fiber than one that nibbles a leaf, which could make transient GI upset slightly more likely — but serious toxicity is not expected based on current data.
