How much alcohol is dangerous for a dog?

There is no safe amount. Dogs are much smaller than people and far more sensitive to ethanol, so even a few laps from a mug can make a small dog visibly drunk — and intoxication in dogs is a medical problem, not a joke.

Doesn't heating the wine burn off the alcohol?

Not reliably. Mulled wine is gently warmed, not boiled down, so plenty of alcohol remains in the glass — and some recipes top it up with rum or spirits after heating.

My glögg had raisins and almonds in it. Does that change things?

Yes — raisins can cause acute kidney failure in dogs with no established safe dose. A dog that fished raisins out of glögg needs a vet call for the raisins alone.

What are the signs of alcohol poisoning in dogs?

Wobbliness, drooling, vomiting and unusual sleepiness come first; severe cases progress to low body temperature, slowed breathing and collapse. Call your vet at the first sign rather than letting them sleep it off.

Can Dogs Drink Mulled Wine? Vet-Sourced Answer

Can Dogs Drink Mulled Wine?

Toxic to dogs

No. Alcohol is toxic to dogs in small amounts, and mulled wine adds sugar and spices — glögg often floats raisins in the glass too.

Why mulled wine is toxic to dogs

Mulled wine is alcohol first and festive garnish second. Ethanol depresses a dog’s central nervous system at doses that seem trivial to humans — dogs are smaller, metabolize alcohol poorly, and the sweetness of a sugary, spiced drink makes it more appealing to them than plain wine. Gentle warming does not remove the alcohol; it just makes an unattended mug smell more interesting.

The garnishes matter too. Scandinavian glögg is traditionally served with raisins and almonds in the glass, and raisins carry their own risk of acute kidney failure. Whole cloves and citrus peel are irritating in quantity, though the alcohol is the headline danger.

The real risks

A slurp or two can leave a small dog ataxic and sedated; larger amounts risk dangerously low body temperature, slowed breathing, low blood sugar and collapse. Signs usually appear within an hour.

What to do if your dog drank some

Estimate how much was in the mug, note whether raisins were floating in it, and call your vet or a pet poison helpline immediately. Do not let a “drunk” dog simply sleep — sedation, hypothermia and breathing depression need monitoring, and raisin ingestion needs its own treatment.

If your dog ate it

If your dog drank mulled wine, call your vet immediately — alcohol poisoning can progress from wobbly to dangerously sedated fast, especially in small dogs. Bring the recipe details if glögg with raisins was involved.
