Can Dogs Eat Raisins?
Safety Information
Dried grapes. Highly toxic.
Important Notes
Can cause acute kidney failure. Emergency vet visit required if ingested.
The Cause: Tartaric Acid
For a long time, the exact reason for the toxicity was unknown. However, veterinary research has identified tartaric acid as the likely culprit. Grapes and raisins contain high concentrations of this acid, and for reasons not fully understood, dogs are uniquely sensitive to it. Ingestion can lead to a rapid and severe decline in kidney function.
Signs of Raisin Toxicity
- If your dog ingests even a small number of raisins, it is a veterinary emergency. Do not wait for symptoms to appear. Signs of poisoning typically develop within 6-12 hours and include:
- Vomiting and/or diarrhea
- Lethargy, weakness, and sluggishness
- Loss of appetite
- Abdominal pain
- Increased thirst and urination, which may progress to a lack of urination (a sign of kidney failure)
What to Do If Your Dog Eats Raisins
1. Contact Your Veterinarian Immediately: This is a time-sensitive, life-threatening emergency. Call your vet or an emergency animal hospital right away for instructions. 2. Do Not Wait: The faster your dog receives treatment, the better their prognosis. Your vet will likely induce vomiting and begin aggressive fluid therapy to support the kidneys.
The Bottom Line
Raisins are one of the most dangerous human foods for a dog. They are extremely poisonous, and the outcome of ingestion can be devastating. Always keep raisins, and any foods containing them (like trail mix, cookies, or bread), securely out of your dog's reach.
Emergency Notice
If your dog has consumed raisins, contact your veterinarian or the ASPCA Animal Poison Control Center (888) 426-4435 immediately.
General Feeding Guidelines
Introduce new foods gradually to monitor for allergic reactions or digestive issues.
Treats and human food should make up less than 10% of your dog's daily caloric intake.
Always consult with your veterinarian before making significant changes to your dog's diet, especially if your dog has pre-existing health conditions.
