Verified against ASPCA/provenance audit 2026-05-06 on May 6, 2026.
Signs to watch for
Vomiting, diarrhea, loss of appetite, lethargy, and potential liver damage.
Escalation note
The toxins in this plant can cause cumulative liver damage. Seek veterinary care promptly if ingestion is observed or suspected.
What to watch for
Extreme drowsiness, weakness, weight loss, and yawning typically come first. Later signs include yellowing of the gums or eye whites (jaundice), abdominal swelling, head pressing or aimless walking, and in severe cases, seizures.
Time window
Liver damage is cumulative; signs often appear days to weeks after ingestion as the injury progresses, and clinical recovery is uncommon once signs are present.
When to call the vet
Call your vet or ASPCA Poison Control immediately for any known ingestion. Treat seizures, head pressing, jaundice, or marked weakness as emergencies.
What this means for your dog
Golden Ragwort poses a serious cumulative risk to dogs. Pyrrolizidine alkaloids damage the liver and even small repeated exposures can add up over months. Treat any known ingestion as a vet-call situation, since liver injury is often advanced by the time symptoms appear.
