Even though humans enjoy raisins and grapes, it does not mean dogs can enjoy these treats as well. Raisins are dried grapes and are toxic to dogs. The exact poisoning function is not known, but raisins can cause acute renal failure. Learn more about the effects raisins can have on dogs by reading below. 

How Toxic are Raisins to Dogs? 

Despite their sweetness, raisins can be harmful. Raisin poisoning in dogs has been documented on many occasions. Toxic effects on dogs include vomiting, diarrhea, and dehydration within 12 hours of ingestion; oliguric/anuric renal failure may develop within 48 hours of intake. 

It does not take a lot for a dog to be poisoned by raisins. Even just a few can be dangerous. Dogs have been poisoned by eating seedless or seeded grape types, commercial or homemade grapes, red or green grapes/raisins, organic or non-organic, and grape pressings from wineries. Raisins may be found in raisin bran cereals, trail mixes, granola mixes, and baked foods. Grape and raisin toxicity is linked to kidney failure and even death in dogs. To ensure your dog is healthy and safe, do not feed them anything that includes raisins. 

Clinical Signs of Raisin Poisoning 

Smaller animals, such as dogs and cats, are more susceptible to toxicities because their bodies cannot metabolize the chemicals in raisins. Raisin poisoning should be handled as an emergency; therefore, you will need to receive veterinarian care as quickly as possible. 

Symptoms include: 

  • Vomiting 
  • Decreased appetite 
  • Weakness 
  • Upset stomach 
  • Urinating more or less
