My dog ate Lantana - what should I do?
Lantana camara
Potentially toxic
Contact your veterinarian or an animal poison-control resource now, especially if any amount was chewed or swallowed.
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 failure in severe cases.
Escalation note
Lantana is considered highly toxic to dogs. If ingestion is suspected, seek immediate veterinary attention to manage potential gastrointestinal and hepatic complications.
First aid at home
Call ASPCA Animal Poison Control at (888) 426-4435 or your veterinarian as soon as possible. Do not induce vomiting unless a veterinarian instructs you to.
What to watch for
Most-common: vomiting, diarrhea, loss of appetite, lethargy, and weakness. Labored breathing has been reported. Less commonly — typically with sustained or large ingestions — yellowing of the gums or eyes (jaundice) signaling liver injury.
Time window
Onset and duration are not well documented for dogs. ASPCA notes liver failure is uncommon and tied to large or repeated ingestions; single small ingestions usually present as GI signs only.
When to call the vet
Call your veterinarian or ASPCA Animal Poison Control (888-426-4435) for any vomiting, diarrhea, weakness, or appetite loss after exposure. If your dog has been getting into lantana repeatedly, treat that as urgent and call right away — repeated exposure is when liver injury becomes a real risk.
What this means for your dog
Dogs that chew lantana most often develop vomiting, diarrhea and weakness from the plant's pentacyclic triterpenoids. ASPCA notes liver failure is possible but rare in dogs — usually tied to long-term browsing or unusually large ingestions, not one mouthful.
