As we head into the autumn, we receive lots of enquiries regarding acorns and oak trees (Quercus species).
Ingestion of acorns by dogs is common during the autumn months. Following a large, one off ingestion of acorns, vomiting and diarrhoea may occur in dogs, both of which may be bloody. Lethargy, abdominal tenderness and inappetence can also be seen and there is also the risk of gastrointestinal obstruction. There have been reports of kidney and liver damage following substantial or repeat ingestion of both acorns and the plant itself, a scenario more commonly seen in horses and ruminants.
Oak toxicity predominantly affects grazing species such as cattle, horses and sheep, but it can affect dogs and cats too.
Oak toxicity can cause:
β Gastrointestinal signs (such as vomiting, diarrhoea, colic)
β Inappetence
β Gastrointestinal obstruction (particularly if a large number of acorns have been ingested)
β Kidney and liver impairment (reported in a small number of cases involving dogs, horses and ruminants)
