Grapes and raisins are highly toxic to pets. Even small amounts may cause serious kidney injury. Contact a veterinarian immediately if ingestion is suspected. No safe amount is known.
Grapes are small vine fruits sold fresh in bunches, dried as raisins, and processed into juices, jams, and snack mixes.
Exposure can come from fruit bowls, raisin bread, trail mix, granola bars, and holiday desserts. Keep grapes and raisins out of reach at all times.
Signs of toxicity may start with vomiting or lethargy before kidney values change. Raisin-containing baked goods and cereals are hidden sources. Grape juice and grape jelly also carry risk.
