What this means for your dog

Daylilies are dramatically more dangerous to cats than to dogs. ASPCA's Hemerocallis entry names cats as the affected species — dogs are not flagged for daylily toxicity, and no daylily-specific syndrome is documented for them.

Sources: ASPCA (cat-specific entry; no dog signs documented).

If a pet has chewed or swallowed plant material and is showing symptoms, contact a veterinarian or poison resource immediately. This product is for structured reference, not diagnosis.

Dogsconcern notes

Common signs

Mild gastrointestinal upset such as vomiting or diarrhea may occur if ingested.

Escalation note

While not listed as toxic to dogs by the ASPCA, ingestion of any non-food plant material can cause digestive upset. Monitor your pet and consult a veterinarian if symptoms persist.
