Conkers, Acorns & Mast
Warning
Common in the UK autumn, Horse Chestnuts (Conkers) and Acorns contain toxins (aesculin and tannins respectively) and pose a serious blockage risk.
Risks:
- Obstruction: The large, hard seeds can easily block the intestine, requiring surgery.
- Toxicity: Vomiting, diarrhoea (can be bloody), abdominal pain, lethargy.
Action Steps:
- Prevent dogs from playing with or eating conkers and acorns.
- If eaten, contact your veterinarian.
- Watch for signs of blockage (vomiting, unable to keep water down).
Important Warning
Puppies are especially at risk of obstruction. "Mast" (accumulated berries/nuts on the forest floor) can also get mouldy, adding a risk of mycotoxin tremors.
