Can Dogs Drink Apple Cider? Hard vs Soft Matters
Updated May 2026
Hard cider contains alcohol
Ethanol is toxic to dogs at roughly 5.5 ml/kg of pure ethanol per the Merck Veterinary Manual entry on ethanol poisoning. A 10kg dog reaches the toxic threshold at about 55 ml of pure ethanol, equivalent to roughly 700 ml of 8 percent ABV hard cider. Lethal dose is lower. Smaller dogs and weaker constitution lower these numbers. Hard cider is not appropriate for dogs in any quantity.
The two ciders, plainly
Soft cider (US sense)
Unfiltered, unpasteurised or fresh-pressed apple juice. Contains no alcohol. Treated the same as apple juice for dogs: not toxic in small amounts but not recommended as a routine treat. Sugar load is the issue.
Common at autumn farm stands in the US. Sometimes pasteurised; check the label.
Hard cider
Fermented apple juice with alcohol content typically 4 to 8 percent ABV. Toxic to dogs as ethanol. In the UK and Ireland, "cider" alone almost always means this; in the US it must be labelled "hard" or "alcoholic."
Includes scrumpy, cyser, ice cider, perry (pear-based hard cider).
Ethanol dose math by dog weight
Toxic ethanol dose in dogs is around 5.5 ml/kg of pure ethanol per the Merck Veterinary Manual, with smaller doses producing intoxication and the lethal dose somewhat higher. The table below shows the approximate volume of 6 percent ABV hard cider that delivers a toxic ethanol load by dog weight. Numbers assume the dog drank the cider quickly and absorbed it; in reality, ingestion rate and concurrent food slow absorption somewhat.
| Dog weight | Toxic ethanol dose (~5.5 ml/kg) | Volume of 6% ABV cider |
|---|---|---|
| 5lb (2.3kg) | ~13 ml ethanol | ~210 ml |
| 10lb (4.5kg) | ~25 ml ethanol | ~410 ml |
| 30lb (13.6kg) | ~75 ml ethanol | ~1.25 litres |
| 60lb (27.2kg) | ~150 ml ethanol | ~2.5 litres |
| 100lb (45.4kg) | ~250 ml ethanol | ~4.1 litres |
These volumes are the theoretical toxic threshold; intoxication signs appear at well below the lethal dose. Toy and very small dogs are at risk from much smaller volumes (a few mouthfuls of a strong cider). The table is illustrative of the dose-response shape, not a permission slip to feed any quantity.
Signs of ethanol intoxication in dogs
Onset is usually within 30 to 60 minutes of ingestion. Per Merck Veterinary Manual:
Any of these signs after possible cider exposure warrants emergency vet attention. Treatment is supportive: IV fluids, glucose if hypoglycaemic, warming if hypothermic, oxygen support if breathing is compromised. Recovery is usually full once the ethanol clears, but the acute phase can be life-threatening for small dogs.
What to do if your dog drank hard cider
- 1Remove access to remaining cider immediately. Take the bottle or glass away.
- 2Note the time of ingestion and estimate the volume consumed. Read the bottle ABV.
- 3Call ASPCA Animal Poison Control on (888) 426-4435 or Pet Poison Helpline on (855) 764-7661. Give the dog's weight, the cider's ABV and the estimated volume.
- 4Do not induce vomiting unless explicitly told to. Ethanol absorbs quickly and induced vomiting after the first 15 to 30 minutes does not help, and can cause aspiration in an intoxicated dog.
- 5If the dog is showing any clinical signs (ataxia, vomiting, lethargy), drive directly to the emergency vet rather than waiting.
- 6Keep the dog warm and quiet during transport. Do not let it drink water voluntarily until vet-assessed; gastric absorption continues for a while.
