Toxicity of Crepe Myrtle to Dogs

Crepe Myrtle (Lagerstroemia indica) is a popular ornamental plant known for its vibrant flowers and smooth bark. Regarding its toxicity, current veterinary and botanical sources indicate that Crepe Myrtle is generally considered non-toxic to dogs. This means that ingestion of leaves, flowers, or bark typically does not result in poisoning or severe adverse reactions in canines.

However, while Crepe Myrtle itself is not classified as poisonous, there are a few important considerations to keep in mind:

  • Mechanical irritation: The bark and woody parts of the plant can cause mild gastrointestinal discomfort if chewed or ingested in large quantities.
  • Pesticide residues: Plants treated with insecticides or herbicides could pose a secondary risk if a dog ingests parts of the plant.
  • Individual sensitivities: As with any plant material, some dogs may experience mild digestive upset such as vomiting or diarrhea if they consume Crepe Myrtle.

Veterinarians typically do not list Crepe Myrtle among common toxic plants to dogs, but accidental ingestion should still be monitored for any unusual symptoms.

Even non-toxic plants like Crepe Myrtle can cause mild symptoms if ingested in notable amounts. Owners should be aware of the following signs that may indicate their dog has consumed plant material and may be experiencing irritation or mild toxicity:

  • Vomiting
  • Diarrhea
  • Drooling or excessive salivation
  • Lethargy or decreased activity
  • Abdominal discomfort or bloating
  • Loss of appetite

If any of these symptoms persist or worsen, veterinary consultation is recommended to rule out complications or secondary causes.
