Frequently asked questions
- Is lantana poisonous to dogs?
- Yes. The ASPCA lists Lantana (Lantana camara) as toxic to dogs, cats, and horses. Its toxic principles are pentacyclic triterpenoids, which can cause vomiting, diarrhea, labored breathing, and weakness. If your dog eats any part of the plant, contact your veterinarian or the ASPCA Animal Poison Control Center at (888) 426-4435.
- Which part of the lantana plant is most dangerous to dogs?
- All parts of lantana contain the toxic triterpenoids, but the unripe (green) berries are widely regarded as the most hazardous. Leaves are also toxic. Because the whole plant is toxic, no part should be considered safe for a dog to chew or swallow.
- What should I do if my dog eats lantana?
- Treat it as a potential poisoning. Remove any plant material from your dog's mouth, note how much may have been eaten and when, and call your veterinarian or the ASPCA Animal Poison Control Center at (888) 426-4435 right away. Severe cases can involve liver injury, so prompt veterinary evaluation is important rather than waiting to see if symptoms develop.
