Acorns are poisonous to horses. This is because they contain toxic substances called Gallic Acid and Tannic Acid.
These acids can cause liver, kidney and intestinal damage to horses eating acorns, oak leaves or branches.
Acorn poisoning is rare but can be a particular problem in the autumn for horses allowed to graze near oak trees.
