Acorns are extremely toxic to dogs due to their gallotannins content. Even small quantities can cause serious kidney damage and gastrointestinal distress in dogs of all sizes. Symptoms appear within hours and include vomiting, diarrhoea, abdominal pain, and lethargy. Never allow your dog to eat fallen acorns during autumn walks. Immediate veterinary attention is required if ingestion is suspected. The toxic compounds accumulate in the system, making even a single acorn potentially dangerous. Keep your dog away from oak trees and dispose of fallen acorns promptly.
