Call Your Vet Immediately
Contact your veterinarian or ASPCA Poison Control at (888) 426-4435 right away. Do not wait for symptoms to appear.
- 2
Note the Amount
Record how many grapes or raisins your dog ate and their weight. This helps determine toxicity risk.
- 3
Vet May Induce Vomiting
If ingestion was recent (within 2 hours), your vet may induce vomiting or administer activated charcoal to prevent absorption.
- 4
Monitor for 72 Hours
Kidney damage may not show symptoms immediately. Watch for vomiting, lethargy, decreased urination, and loss of appetite.
La science derrière
Le composé toxique exact dans les raisins et les raisins secs reste non identifié, mais l'acide tartrique est le principal suspect. Ce composé provoque une nécrose tubulaire aiguë dans les reins, entraînant une insuffisance rénale rapide. La dose toxique est imprévisible — certains chiens développent une insuffisance rénale à partir de quelques raisins seulement, tandis que d'autres en tolèrent davantage. Cette variabilité fait de toute ingestion une urgence médicale (ASPCA, 2023).
Questions fréquentes
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.
