Toxic — never feed

Can dogs eat grapes?

How to prepare them

  • Check trail mix, baked goods, and granola for raisins.
  • Do not wait for symptoms if a known amount was eaten — call for guidance.

Risks & exceptions

  • Grapes and raisins can cause acute kidney injury in dogs.
  • Sensitivity varies, so “my dog ate one once” is not a safety rule.
  • Raisins concentrate the risk in a smaller package.

Grapes are a never-feed fruit for dogs — not an occasional snack.
