Why are Grapes Dangerous?

Researchers do not know how grapes exactly poison dogs. Regardless, dog owners should know grapes and raisin products are dangerous to dogs. Not every dog will exhibit the same symptoms. Grape toxicity can lead to acute kidney failure and lack of urine production in dogs. This can cause dehydration and further complicated matters, as there is no specific antidote for this condition and supportive care is the only viable therapy. It can take up to three days for symptoms to appear. By this time, your dog may be in severe danger. After you immediately suspect that your dog ate grapes, you need to seek medical attention. 

Clinical Signs of Poisoning

The amount of grapes needed to cause poisoning in dogs can vary from dog to dog. A larger dog may ingest a certain number of grapes and only experience mild symptoms, a small dog could eat the same amount and face more serious consequences. If your dog has eaten grapes, it is important to monitor them closely for any signs of toxicity and seek medical help immediately. Possible symptoms include: 

  • Dehydration
  • Vomiting
  • Abdominal pain
  • Bad breath
  • Lack of appetite
  • Increased heart rate
  • Excessive thirst
  • Excessive urination
