My 25 kg dog drank about half a can of beer and was treated by the vet — how long should I monitor him at home and what does recovery look like?

Short answer

You should monitor him closely for at least 24-48 hours after returning home. Recovery involves watching for any return of symptoms like vomiting, lethargy, incoordination, or an elevated body temperature, as hops in beer can cause dangerous overheating. The vet likely provided supportive care like fluids and monitoring of vital signs. Follow all aftercare instructions and contact your vet immediately if you notice any concerning changes in his behavior or appetite.

Alcohol plus hops, both toxic. Hops ingestion also causes dangerous overheating in dogs.

Dogs and cats carry the same rating (Do not feed), so the notes below hold for either pet.

Beer should not be given to dogs at all. Even a small amount can do harm, so there is no portion small enough to be safe.

Do not induce vomiting and do not give milk or oil to “dilute” it. Note the food and roughly how much was eaten, then call your vet or a pet poison hotline and follow their advice on whether to bring the pet in straight away.
