Can Dogs Eat Raisins?

Editor’s Note

It all started one day when my friend’s dog, Billy, got into a bag of raisins that had been left on the kitchen counter. My friend Jane wasn’t home yet, so she didn’t know how much the dog had eaten, but it was clear that he had eaten something because he started exhibiting signs of distress.
Since her dog was a senior, the vet was very concerned about his well-being and recommended that he be hospitalized. Unfortunately, Billy was unable to produce urine and the kidneys were severely damaged. Jane’s vets did everything they could, but the prognosis was fatal, and Billy passed away. Let this story be a lesson to all pet owners to always lock up their food items and make sure that their pets can’t get into them.

Are There Any Benefits to Feeding Raisins to Dogs?

No. While grapes are raisins are known to be nutritious, they are not suitable for dogs and there are plenty of safe alternatives. Dogs can reap the same benefits by eating fruits and vegetables like blueberries, carrots, and bananas that are not toxic to them.

Indeed, it is possible for a single grape to be toxic to dogs and even kill them after ingestion. While it’s not known exactly why some dogs are more susceptible than others, it is known that a small amount of grapes and raisins can cause severe kidney failure in some dogs.

Editor’s Note

Being a veterinary clinic worker, I have witnessed cases of grape and raisin poisoning first-hand. It is a serious issue that can cause death in dogs, especially if not treated promptly. Induced vomiting is necessary in most cases.


Treatment for raisin poisoning in dogs varies depending on the amount of the fruit that the dog has ingested. In most cases, to assist a dog in expelling toxins, a veterinarian may administer an emetic such as apomorphine. This is often followed by activated charcoal to absorb any residual contaminants present within the gastrointestinal tract and intravenous fluids to prevent acute kidney failure.

To prevent vomiting, antiemetics should be prescribed, and the stomach can be safeguarded against uremic gastritis (which is damage to the stomach caused by a high BUN level). BUN, creatinine, calcium, phosphorus, sodium, and potassium levels are carefully monitored. If there is decreased urine production, it can be treated with dopamine or furosemide to help increase urine production.

Prevention Is Always Better Than Cure

If you’re a dog owner and have a bowl of grapes or raisins lying out on the table, it’s important to know that those can be harmful for your pet. Follow these guidelines to be safe:

  • never leave grapes or raising lying around in the house;
  • keep them stored away or on very high counters;
  • make sure your family and friends are aware that raisins are bad for dogs;
  • whenever asked “can dogs eat raisins?”, your answer should be straightforward;
  • never reward your dog with grapes or raisins;
