Grapes are small vine fruits sold fresh in bunches, dried as raisins, and processed into juices, jams, baked goods, and snack mixes. Common table types include green, red, and black varieties, and all are considered unsafe for pets. Toxicity risk does not depend on seedless versus seeded forms.
Exposure can come from obvious fruit bowls or from foods like raisin bread, trail mix, granola bars, and holiday desserts. Even small amounts may cause serious kidney injury in susceptible animals, and no reliable safe dose is known. This is why complete avoidance is recommended.
Toxicity has been reported with fresh grapes, raisins, and foods that contain them as ingredients. Signs may start with vomiting, lethargy, or reduced appetite before kidney values rise. Early veterinary treatment gives the best chance of recovery.
Keep grapes, raisins, and grape-containing foods out of reach. If ingestion is suspected, contact a veterinarian or poison service promptly.
