Successful management of suspected acorn (Quercus petraea) toxicity in a dog

A 7-year-old neutered male Labrador retriever dog was referred to a tertiary care veterinary hospital because of gastrointestinal signs and icterus. The dog developed a hepatopathy and acute kidney injury after ingesting acorns (Quercus petraea) 4 days prior to referral. The dog required hospitalization in an intensive care unit but made a full clinical recovery and was discharged after 6 days. This report documents that dogs can be affected by this toxicity and highlights the need for veterinarians to consider acorns as a potential cause of acute hepatotoxicity and renal injury. To the authors’ knowledge, this is the first reported case of acorn toxicity in a dog.
