Plant identity and scope
This record is limited to Helianthus angustifolius, the accepted species identified by Kew and ASPCA. ASPCA also labels it Sunflower, but this record does not govern the common annual sunflower, Helianthus annuus, or the whole genus.
Governed aliases: Sunflower.
What the evidence supports
The non-toxic result is limited to Helianthus angustifolius. It does not create a genus-wide conclusion and is not a substitute for identifying a different sunflower species.
Safety classifications come from PawPlants' governed evidence record, not from a retailer or product label.
If exposure may have occurred
Remove loose plant material and prevent more chewing. Contact a veterinarian if symptoms persist, a large amount may have been eaten, another substance was involved, or the plant identity is uncertain.
