The Question

“Can dogs eat raisins?” – Sally, mom of Mona and Mabel

Hi Sally,

It’s lovely to hear from a caring dog mom like you. Mona and Mabel are lucky to have someone looking out for their health, especially when it comes to food safety. Raisins, unfortunately, are not safe for dogs. Even in very small amounts, they can cause sudden kidney failure in some cases. The tricky thing about raisins is that the amount of tartaric acid they contain can vary significantly, leading to unpredictable effects.

Not all dogs react the same way. One might eat a handful and appear completely fine, while another could become seriously ill after just one or two raisins. Although tartaric acid is currently the leading suspect, veterinary medicine has not yet definitively confirmed it as the exact toxin. This uncertainty only adds to the concern. Since there’s no known safe amount, it’s best to treat grapes and raisins like toxic substances and keep them well out of reach. If Mona or Mabel ever happen to eat any, even if they seem fine, it’s important to contact your veterinarian right away.

The kidneys are responsible for filtering waste from the blood, and when they begin to fail, toxins quickly build up in the body. In cases of grape or raisin ingestion, signs of kidney distress such as vomiting, loss of appetite, or lethargy can appear within a few hours. If left untreated, a dog can progress rapidly to complete kidney shutdown. Because of the unpredictable nature of this toxicity, the recommendation is that any amount of grape or raisin ingestion should be treated as an emergency. Quick action in these cases can make all the difference in protecting your dogs because early intervention with decontamination and supportive fluids can prevent serious kidney damage.

Keep up the proactive care
