Canine Kidney Failure May be Linked to Raisins, Grapes

The ASPCA Animal Poison control Center (APCC) is looking into a possible connection between kidney failure in dogs and the digestion of grapes or raisins.

A review over the past two years showed 10 dogs with evidence of developing kidney dysfunction after ingesting large amounts of either raisins or grapes, according to the APCC's Jill A. Richardson, DVM.

She said she estimated amount of raisins or grapes eater by the dogs ranged between 9 ounces and 2 pounds. The grapes came from grocery stores, vines in private yards or fermented grapes from wineries. The raisins involved were mostly commercial sun-dried raisins of various brands. None of the grapes or raisins ingested came from pet treats or food, Richardson said.

Vomiting was reported in all of the dogs and began within the first few hours of ingestion. Anorexia, diarrhea, lethargy and signs of abdominal pain were also reported. After aggressive treatment, which included intravenous fluids and medications, half of the dogs recovered and the others died or had to be euthanized.

Because the exact role of grapes or raisins in there cases is still unclear, Richardson said the APCC is working on a study with Colorado State University's College of Veterinary Medicine to determine how the fruit contributed to these dog's sickness and, in some cases, death.

When asked if any amount of raisins or grapes would be safe for a dog to consume, Richardson said, "I don't know if there is a safe amount, but until we can find out, I wouldn't recommend giving dogs any raisins or grapes."
