"No, dogs should not eat grapes or raisins as they can be toxic and cause kidney damage, which can be life-threatening. Even small amounts of grapes or raisins can cause severe reactions in some dogs.
The exact substance in grapes that causes toxicity is not yet fully understood, and not all dogs are affected the same way, but it is best to err on the side of caution and avoid feeding grapes and raisins to dogs altogether.
If your dog accidentally eats grapes or raisins, it is important to contact your veterinarian immediately.
