Can dogs eat alcohol?

No — alcohol is highly toxic

No. Dogs cannot process alcohol safely. Even small amounts cause dangerous drops in blood sugar, blood pressure, and body temperature. Larger amounts can be fatal.

If your dog has just eaten alcohol

Do this now

  1. Call your vet immediately — tell them exactly what was drunk and approximately how much
  2. If your vet is closed, call the Animal PoisonLine on 01202 509000 or go to an emergency vet
  3. Do not wait for symptoms — they can escalate fast
  4. Keep your dog warm (alcohol can cause hypothermia)
  5. Do NOT give food or water if your dog seems sedated — aspiration risk

The full picture

Alcohol affects dogs much more severely than humans. Their smaller size and different metabolism mean even a splash can cause problems, and moderate amounts can be fatal. This includes the obvious — beer, wine, spirits, cocktails — but also unseen alcohol sources: rum-soaked Christmas cake, fermenting raw bread dough (which continues to produce alcohol in the stomach), leftover pint glasses at parties, rotten fallen fruit, some mouthwashes, and hand sanitisers. Never deliberately give alcohol to a dog 'for a laugh' — this is genuinely dangerous.

Where alcohol hides

Alcohol can turn up in foods you wouldn't expect. Check for it in:

  • Rum-soaked Christmas cake, trifle, tiramisu
  • Raw bread or pizza dough — ferments in the stomach producing ethanol
  • Fermenting fallen fruit in gardens (apples, plums, pears)
  • Some mouthwashes and hand sanitisers
  • Alcohol-based cough syrups
  • Vanilla extract (some contain significant alcohol)
  • Unattended drinks at parties

Risks to watch for

  • Severely low blood sugar
  • Dropped body temperature (hypothermia)
  • Respiratory depression
  • Vomiting and loss of coordination
  • Coma
  • Death at higher doses

Safe portion size

None. Zero.
