Safety status
What this means for your dog
Dogs do not face the kidney-failure risk that makes daylilies (Hemerocallis) deadly to cats. ASPCA lists Hemerocallis as toxic to cats only — dogs that nibble petals or leaves typically experience nothing worse than a mild stomachache. The plant is still not edible for dogs, but a casual taste is not an emergency.
What to watch for
Mild vomiting or diarrhea after ingestion. Reduced appetite or temporary lethargy. Symptoms tend to be self-limiting in dogs.
Time window
Exact timing not well documented for dogs; mild GI signs typically appear within a few hours of ingestion and resolve within 24 hours.
When to call the vet
Call your vet if vomiting or diarrhea persist beyond 12 hours, if your dog ate a large quantity, or if you see signs of dehydration (sunken eyes, tacky gums, refusal to drink).
