If in doubt, always call your vet or the Animal Poison Line immediately.

Why It's Dangerous

Horse chestnuts (conkers) contain aesculin, a saponin-type compound toxic to dogs, and the hard nuts themselves are also a significant choking and intestinal blockage hazard.

Symptoms to Watch For

  • Vomiting
  • Diarrhoea
  • Abdominal pain
  • Lethargy
  • Signs of blockage if a whole conker was swallowed

Vet Guidance

Contact your vet if your dog has eaten conkers, both because of the aesculin toxin and the real risk of intestinal blockage from the hard nut.
