Common grape vine is highly toxic for dogs

Vitis vinifera highly toxic

Grapevines are woody, climbing shrubs that grow similarly to lianas when not cut. They are used as cultivated plants for the production of grapes and wine or as ornamental plants in gardens or on walls. The leaves, green in summer, are large and typically heart-shaped. The flowers are inconspicuous, the fruits come in the form of green or red hanging grapes.

Especially for dogs, the grapes are very poisonous. The other parts of the plant, however, are only slightly poisonous.

The following symptoms may occur with grape poisoning:

  • burning sensation in the mouth
  • increased salivation
  • nausea
  • vomiting
  • stomach pain
  • diarrhoea
  • lethargy

Later, decreased urine output and even failure to pass urine may develop. Death may occur due to kidney failure.


The vet will always try to remove the ingested poison from the body and alleviate the specific symptoms of poisoning.

There are different methods to remove the poison from the body:

1. ACTIVATED CHARCOAL: Activated charcoal can absorb toxins. If possible, it should be administered within 2 hours after ingestion of the poison, so that the toxin does not enter the bloodstream.
2. LAXATIVES: The vet may combine the administration of activated charcoal with a laxative.
3. VOMITING: The vet can also induce vomiting using medication to remove the toxin from the body. 

Furthermore, depending on the degree of poisoning, the vet can administer infusions and, if necessary, try to support the kidney functions.
