My dog ate lantana leaves. Is it toxic? Does he need a vet visit?

Updated on September 23, 2025

Pet's info: Dog | Mixed Breed Medium (23 - 60lb) | Male | neutered | 26 lbs

I live in Phoenix and caught my 10 yr old frenchie/Boston mix nibbling in West Indian (orange) Lantana leaves. The shrub was pruned 2 weeks ago and there are no berries (never berries) or flowers on the shrub. He weighs 26# and probably didn't eat more than a leaf or two in total. Also unsure if this is the first time he has eaten lantana b/c he has been exposed to the shrubs for over 7 years. Should I take him to vet?

Hello, sorry to hear about Bubba. Yes you should take him to the vet to have him induce vomiting and remove as much plant material as possible.

Lantana species can commonly cause vomiting, diarrhea, and decrease appetite. However the most concerning side effect is damage to the liver which could lead to liver failure.

Your veterinarian may recommend obtaining baseline liver values and monitoring these over the next month to ensure there's no liver damage.

Best of luck and hope this helps.
