Verdict

Grapes and raisins can cause acute kidney (renal) failure in dogs. The toxic compound has not been definitively identified, but the reaction can occur with any variety — seedless, seeded, red, green, or peeled. Even a small number of grapes can be fatal to some dogs, while others appear unaffected; there is no safe dose.

Symptoms to watch for

  • vomiting within a few hours
  • lethargy and weakness
  • loss of appetite
  • decreased or no urination
  • abdominal pain
  • kidney failure

What to do

This is an emergency. Contact your vet or ASPCA Poison Control (888-426-4435) at once. If ingestion was recent, your vet may induce vomiting and administer IV fluids to protect the kidneys.
