Are grapes poisonous to dogs

Can dogs eat grapes?

About 20 years ago researchers discovered for the first time that grapes, raisins and currants (fruits of the genus Vitis) are poisonous for dogs. The number of dogs that die from poisoning with these fruits has been rising steadily since then.


What types of grapes are poisonous to dogs?

Cases of poisoning are known in which dogs have eaten seedless or seeded grapes, purchased grapes, garden-grown grapes, green or red grapes, organically grown and commercial grapes or grape must.

Any food that contains grapes, raisins and currants - whether it's a muesli mix, an energy bar or a piece of cake - is a potential hazard to dogs!


How much does a dog have to eat to poison itself?

So far, no lethal dose or the smallest toxic dose has been established. What is certain is that when dogs eat large amounts, the more likely symptoms of poisoning are to appear. However, some dogs show individual sensitivity. Some dogs can tolerate grapes in certain amounts, while others die from the same amount of fruit. Just a few grapes or raisins may be enough to cause poisoning. So far there is no way of predicting which one Dog grapes can tolerate.


Why are grapes, raisins, and currants poisonous to dogs?

So far nothing is known about the mechanism of action. Some researchers suspect certain fungal toxins. Others suspect that salicylates (similar to the active ingredient in aspirin), which are found in small amounts in grapes, raisins, and currants, disrupt blood flow to the kidney, causing kidney failure. So far, however, the toxic substance has not been identified. Therefore, any ingestion of the fruit in dogs should be a cause for concern.


What should I do if my dog ​​has eaten grapes?

Dogs that have eaten grapes should be taken to the veterinarian immediately. As long as the fruit is still in the stomach, the vet can make the dog vomit and thus render the fruit harmless. To do this, it is important that you go to the vet immediately before the fruit has passed into the intestine.

As with any poison, the sooner treatment is started, the less likely it is to have severe consequences.


What signs does my dog ​​show when poisoned with grapes, raisins or currants?

The most common and first sign of poisoning is vomiting. This occurs within the first 24 hours. In addition, dogs can show decreased appetite, listlessness and possibly diarrhea within 12-24 hours. Usually no further signs are noticeable within the first two days. Only then do the signs of acute kidney failure develop, these consist of:

  • nausea
  • Lack of appetite
  • Vomit
  • The breath smells like urine
  • diarrhea
  • stomach pain
  • Strong thirst
  • Increased urination
  • Tremble
  • cramps

As the poisoning progresses, the kidneys can stop functioning completely, so that the dog no longer has to pass any urine. As a result, there is a sharp rise in blood pressure, as a result of which the dog loses consciousness and dies. Dogs that stop producing urine are unlikely to survive.


How is grape poisoning diagnosed in dogs?

Unfortunately, the signs of such poisoning are very unspecific. Acute kidney failure can be caused by many other factors. Your vet will therefore carry out various tests. It is important that you as the pet owner tell your vet that you Dog grapes has eaten. Sometimes grapes are found in the vomit (this is one of the reasons why it is important to always look closely at what an animal is vomiting!)


How is grape poisoning treated?

If the ingestion of grapes has been observed, induction of vomiting is the treatment of choice. It can still make sense to induce vomiting up to 6 hours after ingesting grapes. After this decontamination, the dog is given medical charcoal and given fluid therapy via the vein (medical infusions) for at least the next two days. In this way, absorbed toxins are excreted more quickly and blood pressure remains constant. It is important that the infusion runs as uninterrupted as possible. A stay in a veterinary clinic is therefore necessary. The blood values ​​must be checked every 2-3 days.


What are the chances of survival for a dog with grape poisoning?

The chances of survival depend on a large number of influencing factors. On the one hand, the amount of fruit consumed, the time to treatment and the expression of clinical symptoms play a role. Only the attending veterinarian can state the individual chances.
