Is Persicaria orientalis toxic to dogs?

Persicaria orientalis

Mildly toxic to dogs

Mildly. The ASPCA lists persicaria orientalis 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. Persicaria orientalis is not individually listed on the ASPCA's toxic or non-toxic plant database; treat with caution and verify with a vet. Some knotweeds (Persicaria/Polygonum) contain oxalates and skin-irritant sap, so it is prudent to discourage pets from chewing the foliage.

What to do if your dog ate persicaria orientalis

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

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