Is White Oak toxic to dogs?

Quercus alba

Toxic to dogs

Yes — white oak is toxic to dogs according to the ASPCA. Keep it well away from any dog that chews plants; reactions can be significant. This classification follows the ASPCA Toxic and Non-Toxic Plant List. Oak (Quercus) is ASPCA-listed as toxic to dogs, cats and horses. The toxic agents are tannins (gallotannic/tannic acid), highest in acorns, buds and emerging leaves. Signs of ingestion include vomiting, diarrhoea that may be bloody, lethargy, abdominal tenderness and loss of appetite; heavy or chronic intake risks kidney and liver injury, and whole acorns can obstruct the gut. Keep acorns and leaf litter away from pets and grazing animals.

What to do if your dog ate white oak

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