Call Your Vet Immediately
Contact your veterinarian or ASPCA Poison Control at (888) 426-4435 right away. Do not wait for symptoms to appear.

Note the Amount
Record how many grapes or raisins your dog ate and their weight. This helps determine toxicity risk.

Vet May Induce Vomiting
If ingestion was recent (within 2 hours), your vet may induce vomiting or administer activated charcoal to prevent absorption.

Monitor for 72 Hours
Kidney damage may not show symptoms immediately. Watch for vomiting, lethargy, decreased urination, and loss of appetite.
その背後の科学
ブドウとレーズンの正確な有毒化合物はまだ特定されていませんが、酒石酸が主要な容疑物質です。この化合物は腎臓の急性腎小管壊死を引き起こし、急速な腎不全に至ります。有毒量は予測不可能です—一部の犬は数個のブドウから腎不全を発症しますが、他の犬はより多く耐えます。この変動性により、あらゆる摂取が緊急事態となります（ASPCA、2023）。
よくある質問
How many grapes are toxic to dogs?
The toxic dose is not established, but as few as 1-2 grapes can cause kidney failure in some dogs. Raisins are more concentrated and thus more dangerous. There is no known safe amount — any ingestion should be treated as an emergency.
How long after eating grapes do symptoms appear?
Vomiting and diarrhea typically begin within 6-12 hours. Signs of kidney failure (decreased urination, lethargy, loss of appetite) may not appear until 24-72 hours after ingestion. Early veterinary intervention is critical.
Why are grapes toxic to dogs?
The exact toxic mechanism is still unknown. Tartaric acid is the suspected toxin, with varying concentrations between grape varieties. This unpredictability makes any grape ingestion potentially dangerous.
