Condensed tannins in grapes prove to be extremely harmful to the dogs. It is considered to be a possibility that ochratoxin, flavonoids, polyphenolics, and monosaccharides are toxic to the dogs. There is significant difference in the vulnerability of dogs to grapes noxiousness. The quantity of grapes taken was 12 to 31 gram per kilogram body weight in a controversial series of grape toxicity. The poisonous dose of raisins is 0.1 oz per kilogram of physical weight.

According to a study, four to five grapes proved to be toxic to a dog that weighed 8.2 kilograms. It is quite natural that toxicity gets more intense with the increasing amounts of grapes ingested. However, it was also documented that some animals were asymptomatic even after they had taken 1 kilogram of raisins. The mechanism of toxicity is believed to be some nephrotoxic substance or idiosyncratic reaction that leads to hypovolemic shock and kidney disorder.

First instances of grapes toxicity

It was in the year 2003 that Animal Poison Control Center recognized the case of grapes toxicity. This organization is handled by the American Society for the Prevention of Cruelty to Animals. Starting from April 2003, more than 100 subjects were examined by APCC in that year. Out of those cases, 50 showed the symptoms of grapes poisoning. It proved to be fatal for seven dogs.

Evaluation of risk

Dogs might have been fed with these fruits by mistake by a family member.. Such dogs are considered to be at risk of grapes toxicity. The toxic dose is absolutely minute. It is in the range of 0.03 to 0.13 ounces per pound of body weight of grapes and 0.15 to 0.43 ounces per pound of body weight for raisins.

Clinical signs and features of toxicity with grapes

The initial presenting sign in dogs is emesis in a day after consumption of the fruits. It usually appears that the ingested fruits have been discarded through the vomit. This, however, is not the case. Vomiting ensues for several hours and the dog gets dehydrated and weak. As a result, it may even get unconscious and die.

You may find the stool or vomitus filled with chunks of grapes or raisins that are partially digested. Dogs appear dull with oliguria or anuria associated with isothenuria sometimes. Azotemia may also be noticed in a number of cases. This is generally because of delay in recognition of the condition and subsequent delayed referral to a veterinary doctor. When the renal failure becomes severe, it leads to serious abnormalities in the metabolism and anuria that can lead to euthanasia as a result of poor response to the treatment. It can also lead to loss of appetite, lethargy, unusual calmness in the dog and abdominal pain. Finally, when the condition remains untreated and continues to deteriorate, it can lead to death.


Laboratory findings include increase in blood urea nitrogen (BUN) and creatinine along with rise in the levels of phosphorous and calcium in the blood within 2 days of ingesting the fruits mentioned. When the kidney is biopsied, it frequently shows evidence of necrosis in the tubules of the kidney which is a serious finding that is not limited to just one area. Moreover, it can also show a collection of enigmatic pigment of golden-brown color inside the epithelial cells of the kidney.

The diagnosis is usually confirmed with the help of positive history of exposure, clinical signs, and histopathologic findings. Mineral analysis of two kidneys collected from a poisoned dog indicated a slightly higher calcium to phosphorous ratio of 0.12 and 0.29 where normal is less than 0.1.


Prevention is the primary key to this condition. Sometimes, despite all the necessary vigilance and preventive measures, dogs may consume grapes or raisins. If you see a dog eat grapes or raisins, you can induce vomiting with the help of hydrogen peroxide, a concentrated salt solution, or ipecac syrup. If ipecac is used, administrate 0.5 to 1 cc per pound of body weight up to a maximum of 15 cc. A heavy concentrated salt solution can be prepared immediately by heating water and adding ample salt to it. Once the salt dissolves, use the solution prepared to induce vomiting. As another option, you can even administer activated charcoal orally.

Call a poison control center or your veterinary doctor as early as possible. Dogs should be treated with appropriate therapy that helps in maintaining renal function. The bottom line remains that dogs with grapes poisoning should be managed very aggressively. Prompt decontamination of the gastrointestinal system through induced vomit and lavage is strongly advisable. The Vitis fruit remains in the gut for some time and that is why emesis should be continued for 120 minutes.

It is inevitable to cautiously monitor the central venous pressure and urine output so that there is no overload of fluids. Other treatments include furosemide, dopamine, mannitol, H2– antagonists and hemodialysis or dialysis of the peritoneum.


If the dogs show ataxia, weakness and renal failure, the prognosis is poor. If these conditions are successfully overcome, it can bring the animals out of danger.
