Are Raisins Good for Dogs?

Unfortunately no. Raisins are not good for your dog’s health. Though considered a healthy and scrumptious snack for people, raisins can have fatal effects on a dog. Even when combined with other foods, the toxicity of raisins can add up and harm your pet.

While researchers have looked into the exact reason why raisins are harmful to dogs, there has yet to be sufficient information that sheds light on the subject.

Though still inconclusive, it’s long been suspected that the salicylate or the mycotoxins present in dried grapes are the reason for their toxicity. These substances reduce the blood flow to a dog’s kidneys and can lead to renal failure and a host of other troubling symptoms.

Additionally,  dogs may be unable to metabolize the tannins, flavonoids, and monosaccharides in raisins. More recently, reasons for toxicity have shifted to the tartaric acid in raisins.

Are Cooked Raisins Toxic to Dogs?

Yes, this includes cooked raisins as well as seedless, skinned, unskinned, baked, and all manners of raisins you can find.

Aside from death and renal failure, you’ll understand why it’s better to deprive your four-legged friend of this tasty treat when you see the full list of symptoms that your dog can suffer.

What Happens if My Dog Eats Raisins?

By allowing your dog to ingest raisins, you expose it to a myriad of risks that include:

  • Renal failure
  • Dehydration
  • Abdominal pain
  • Loss of appetite
  • Excessive urination and thirst
  • Diarrhea
  • Weakness
  • Tiredness
  • Uremic breath
  • Vomiting

Tip: A quick way to check for dehydration is to check for pale gums or if your dog’s mouth and nose are dry.

If left untreated and your dog’s system cannot handle it, these symptoms can lead to kidney failure. Once the kidneys stop functioning, the build-up of substances inside your dog’s body can also lead to a coma.

Even if your dog ate raisins and is fine, it’s better not to take any chances. If your dog displays any of these symptoms, contact your vet or an animal poison control service immediately.

How Will the Vet Treat Poisoning?

If your dog ingests raisins and you need to bring them to the vet, it will be given treatment for poison ingestion that starts with a decontamination process. In decontamination, your vet will try to induce vomiting to get the raisins out of your dog’s stomach.

One of the methods for inducing vomiting is giving your dog a solution with 3% hydrogen peroxide. The exact quantity will be adjusted according to your dog’s age and weight. Unless advised by your vet, you should not try to do this yourself especially in cases where there is a breathing problem or your dog becomes unconscious.

After your dog vomits, your vet will attempt to clear the remaining raisins by giving your dog activated charcoal.

In extreme cases, your vet may recommend hospitalization for up to 48 hours. During hospitalization, your dog will be given intravenous fluid therapy to monitor the functioning of your dog’s kidneys. Additionally, blood work might be required for one to two days after taking your pet home.
