Why It's Dangerous

Acorns contain tannins that are toxic to dogs, causing damage to the kidneys and gastrointestinal tract. Even a moderate amount can cause significant illness, and the toxic compounds accumulate with repeated exposure.

Symptoms to Watch For

  • Vomiting
  • Diarrhoea (sometimes bloody)
  • Abdominal pain
  • Lethargy
  • Signs of kidney damage with larger or repeated exposure

Vet Guidance

Contact your vet if your dog has eaten a meaningful number of acorns, particularly during autumn when fallen acorns are widespread.
