Is Shingle Oak toxic to dogs?

Quercus imbricaria

Mildly toxic to dogs

Mildly. The ASPCA lists shingle oak 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. Shingle Oak contains tannins and gallic acid in its acorns and foliage, as do all Quercus species. ASPCA lists Quercus (oak) as toxic to dogs, cats, and horses. Ingestion of leaves or acorns — particularly in quantity — causes vomiting, diarrhea, and potential kidney injury. The winter-persistent marcescent leaves also remain a risk for browsing livestock when fresh foliage is absent.

What to do if your dog ate shingle oak

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

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