What makes it harmful
ethanol (also in cooked alcohol sauces, fermented foods, and rising yeast dough)
How much is dangerous
The published oral lethal dose in dogs is ~5.5–7.9 g of pure ethanol per kg body weight (Today’s Veterinary Practice). Dogs are much smaller than people and clear alcohol poorly, so even a few laps of beer or wine — or fermented bread dough that keeps producing alcohol — can poison a small dog. Signs appear within 15–90 minutes.
Symptoms to watch for
Mild / early
- • Vomiting
- • Wobbly walking (ataxia)
- • Drooling
- • Disorientation
Severe — vet urgently
- • Metabolic acidosis
- • Slow breathing (respiratory depression)
- • Dangerously low blood sugar and body temperature
- • Coma
- • Death
What to do if eaten
This can be an emergency — contact a vet right away, especially for a small dog. Bring the product so the ethanol amount can be estimated.
