Is Citronella Grass toxic to dogs?

Cymbopogon nardus

Mildly toxic to dogs

Mildly. The ASPCA lists citronella grass as mildly toxic to dogs — a chewing dog typically gets mouth irritation, drooling, and vomiting rather than a medical emergency, but it is still best kept out of reach. This classification follows the ASPCA Toxic and Non-Toxic Plant List. The ASPCA lists Cymbopogon nardus (citronella grass) as toxic to dogs and cats, noting it can cause symptoms including skin irritation, gastrointestinal upset (vomiting, diarrhoea), muscle weakness, and depression if ingested in significant quantities. The essential oils are the primary irritant. Keep pets away from the plant and especially away from concentrated citronella oil products.

What to do if your dog ate citronella grass

  1. Remove any plant material from your dog's mouth and move citronella grass out of reach.
  2. Note how much was eaten and when, and watch for drooling, vomiting, or lethargy.
  3. Do not induce vomiting unless a vet or poison-control specialist instructs you to.
  4. Call your vet or the ASPCA Animal Poison Control Center on (888) 426-4435 and follow their advice.
  5. Bring a leaf or photo of citronella grass to the appointment so it can be treated correctly.

General guidance, not veterinary advice. If you think your dog has eaten citronella grass, contact your vet or the ASPCA Animal Poison Control Center on (888) 426-4435 — do not wait for symptoms to worsen.
