Toxic — skip

Can dogs eat coffee?

Dogs should not have coffee. Caffeine is toxic to dogs at relatively small amounts compared with humans, and espresso, cold brew, and grounds concentrate the risk further.

Not medical advice — general pet-safety info only. Confirm with your vet before changing your dog’s diet.

Risks & exceptions

  • Caffeine can cause vomiting, tremors, seizures, and heart arrhythmias.
  • Grounds and beans pack more caffeine per bite than diluted brew.

Coffee is not safe for dogs in any form you would drink.

If your dog ate any

A larger portion or the wrong preparation is most likely to cause trouble.

Call your vet / pet poison line if:

Coffee contains caffeine, which is toxic to dogs. Contact a veterinarian or pet poison hotline immediately if your dog drank coffee or ate beans or grounds.
