Is Blue Ash toxic to dogs?

Fraxinus quadrangulata

Mildly toxic to dogs

Mildly. The ASPCA lists blue ash 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. Fraxinus species are not prominently listed by ASPCA as toxic to companion animals. However, ash seeds (samaras) and bark have been associated with mild gastrointestinal upset in horses and livestock when ingested in quantity. As with many landscape trees, restrict access by horses to avoid accidental ingestion of large leaf or seed quantities. Not considered significantly toxic to dogs or cats based on current ASPCA data.

What to do if your dog ate blue ash

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

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