Is Common Bistort toxic to dogs?

Persicaria bistorta

Mildly toxic to dogs

Mildly. The ASPCA lists common bistort 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. Not listed on the ASPCA toxic-plant database, but the plant contains oxalic acid and tannins. Ingestion of large amounts may cause gastrointestinal upset in pets; it should not be offered as forage. Individuals with kidney stones, gout, or rheumatism should also avoid consuming the leaves.

What to do if your dog ate common bistort

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