Can dogs eat grapes? Why they are dangerous

Grapes and raisins can cause serious kidney damage in dogs. A safe amount is not known, so it is important to act quickly.

Fresh grapes, raisins, sultanas and foods containing dried grapes can be toxic to dogs. How sensitive an individual dog will react cannot be reliably predicted. Some animals become ill after consuming a seemingly small amount, others initially show no symptoms after ingesting a larger amount.

Current scientific evidence links the poisoning to tartaric acid and its salts. The content can vary greatly between fruits and products. Therefore, there is no amount that can be considered safe for every dog.

The first symptoms often begin within six to twelve hours. Possible symptoms include:

Acute kidney injury can develop within one to three days. Some dogs then pass significantly less or no urine at all. Don't wait for these late signs.

If your dog has eaten grapes or raisins, call a veterinary practice or veterinary hospital immediately. Include weight, approximate quantity, timing and product. Packaging or ingredient lists can provide important information for processed foods.

Do not induce vomiting yourself or give home remedies. The vet decides whether controlled emptying of the stomach makes sense and is safe. The earlier treatment begins, the better the ingested substances can be removed and the kidneys can be protected through fluid therapy and monitoring.

Raisins are not only found in muesli. They can be found in trail mix, rolls, cakes, chocolate, biscuits and savoury dishes. When it comes to chocolate or other ingredients, several dangers can exist at the same time.

Keep grapes, raisins and related foods closed and out of reach. Ask guests and children not to give anything from the table to the dog. After baking or picnicking, check the floor for fallen pieces.
