Acorns are toxic to dogs because they contain tannins, a type of chemical that can cause stomach upset and, in severe cases, liver and kidney damage. Eating acorns can lead to symptoms such as vomiting, diarrhea, abdominal pain, loss of appetite, dehydration, and in rare cases, even death. Acorns can also cause physical issues like choking or intestinal blockages, especially in smaller dogs. If a dog has ingested acorns, it is important to contact a vet immediately for advice and possible treatment.

Why Acorns Are Dangerous

• Contain tannins that are toxic to dogs and hard to digest
• Can cause severe stomach upset, kidney and liver issues
• May cause choking or blockages if swallowed whole or in large pieces

Symptoms to Watch For

• Vomiting and diarrhea (sometimes with blood)
• Abdominal pain and loss of appetite
• Lethargy, dehydration, and in severe cases, collapse

What to Do

• Prevent dogs from chewing or swallowing acorns during walks
• Contact a vet immediately if ingestion is suspected
• Treatment may include medication, rehydration, and possibly surgery if blockages occur

Additional Risks

• All parts of the oak tree (bark, leaves, wood) contain toxins harmful to dogs
• Risk increases with the amount ingested and frequency of ingestion

Being vigilant during autumn walks under oak trees and training dogs to avoid acorns can help prevent poisoning incidents.
