Is wavy hair grass toxic to dogs?

Deschampsia flexuosa

Mildly toxic to dogs

Mildly. The ASPCA lists wavy hair 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. Deschampsia flexuosa is not individually listed in the ASPCA Toxic and Non-Toxic Plants database, so a definitive pet-safe status cannot be confirmed; treat with caution and verify with a vet. As with any grass, ingestion of large amounts may cause mild gastrointestinal upset or vomiting in cats and dogs.

What to do if your dog ate wavy hair grass

  1. Remove any plant material from your dog's mouth and move wavy hair 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 wavy hair grass to the appointment so it can be treated correctly.

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