Also known as: Shrub Verbena, Yellow Sage, Lantana camara · Lantana camara

What makes it toxic

Lantadene A and B, pentacyclic triterpenoids found throughout the plant and concentrated in leaves and unripe berries. They are hepatotoxic and irritate the gastrointestinal lining.

Warning signs to watch for

Drooling, vomiting, diarrhea, weakness and loss of appetite within a few hours. Serious cases develop jaundice, dark urine, excessive thirst and signs of liver failure over one to three days.

What to do if your dog eats it

Take away any plant material and call your vet promptly, especially if a lot was eaten. Jaundice, repeated vomiting or profound lethargy means an emergency clinic visit right away.

Common questions

My dog ate a few lantana leaves — will he be okay?

A small nibble usually causes only mild stomach upset, but monitor closely for vomiting or lethargy and call your vet if any sign appears or worsens.

Why is lantana poisoning worse for grazing dogs?

Dogs that repeatedly browse the plant get a cumulative liver load. Livestock suffer severe chronic lantana poisoning the same way, and the same compounds are responsible.

Is dried lantana in hay or mulch still toxic?

Yes, the toxins persist in dried plant material, so keep dogs away from dried lantana in mulch, hay or garden waste.
