We know that grapes are toxic to dogs, but does that include raisins as well? The answer is YES! Raisins are simply dried grapes, and all products that contain grapes and raisins are highly dangerous to dogs. Now that we know that all grape products are dangerous, let’s learn why and the signs of toxicity below:

Why are Raisins Toxic? 

Even though we know they are toxic, scientists do not completely understand how raisins and grapes poison dogs.  A recent theory suggests tartaric acid is the main culprit, however, this has not yet been proven. Tartaric acid attacks your dog’s kidneys and makes them less efficient, and potentially causes kidney failure to occur. Tartaric acid is found in low levels in other foods, including bananas and citrus fruits. These other foods are not a risk of poisoning concerns, however.  Kidneys are responsible for balancing nutrients and filtering out waste from your dog’s body. 

Symptoms of Raisin Poisoning

Even a couple of grapes or raisins can result in severe consequences for your dog. It is best to never let your dog eat any grape or raisin products. Inform the people that interact with your dog about the consequences of dogs and raisins. 

Symptoms include:

  • Vomiting and/or nausea
  • Feces containing raisins or grapes
  • Reluctance to eat
  • Weakness
  • Upset stomach
  • Excessive thirst and increased urination or lack of urination 
  • Body shivers
  • Diarrhea

There are many other types of food you can feed your dog instead of raisins. Blueberries, raspberries, apples, and mango are healthy alternatives. Speak with your veterinarian if you have any questions or concerns.
