My dog ate columnar english oak — FAQ

Is columnar english oak poisonous to dogs?

Yes — the ASPCA lists Columnar English Oak (Quercus robur 'Fastigiata') as mildly toxic to dogs. Quercus robur acorns and leaves contain tannins (gallotannins) that can cause gastrointestinal upset and, if consumed in large quantities, renal damage in dogs, cats, and horses. The ASPCA lists oak (Quercus species) under plants toxic to horses. For dogs and cats, significant acorn ingestion warrants veterinary attention. 'Fastigiata' presents the same risk as the species.

How serious is it if my dog ate columnar english oak?

Columnar English Oak is mildly toxic, so most dogs get short-lived mouth irritation, drooling, and vomiting rather than a life-threatening reaction. It is still worth a vet call to be safe, especially if your dog ate a lot or symptoms persist.

What symptoms should I watch for?

Signs usually appear soon after chewing: drooling, pawing at the mouth, vomiting, loss of appetite, or unusual lethargy. Quercus robur acorns and leaves contain tannins (gallotannins) that can cause gastrointestinal upset and, if consumed in large quantities, renal damage in dogs, cats, and horses. The ASPCA lists oak (Quercus species) under plants toxic to horses. For dogs and cats, significant acorn ingestion warrants veterinary attention. 'Fastigiata' presents the same risk as the species. Any worsening or persistent symptoms warrant an immediate vet visit.

Should I make my dog vomit?

No — do not induce vomiting unless a vet or a poison-control specialist specifically tells you to. The wrong action can make things worse. Call your vet, or (888) 426-4435 in the US, or Animal PoisonLine on 01202 509 000 in the UK, and follow professional advice.
