Grapes, raisins and sultanas are common household snacks which contain compounds that can be toxic to dogs. Dogs are the only species recorded to suffer from the toxic effects of these fruits, but it has also been suggested that cats and ferrets may also be susceptible to the toxins. The exact substance responsible for this toxicity remains unidentified, making it challenging to predict how each dog will react. It has recently been hypothesised that tartaric acid and its salt, potassium bitartrate, may be the responsible toxin. Tartaric acid concentrations do vary depending on the ripeness of the fruit, which results in inconsistencies in the amount of fruit required to be ingested to cause toxicity. However, what we do know is that ingestion of even small quantities of grapes or raisins can lead to severe health issues, including kidney failure.
Recognising the Signs
Early detection is essential in addressing grape toxicity in dogs. Keep an eye out for symptoms such as vomiting, diarrhoea, lethargy, loss of appetite, abdominal pain, dehydration, and decreased urine production. If your dog displays any of these signs, and you suspect grape ingestion, seek veterinary care immediately.
What to do if your dog ingests grapes, raisins or sultanas
In cases of grape ingestion, swift action is crucial. Firstly, remove any further access your dog may have to the remaining grapes or raisins. Next, contact your veterinarian for guidance. Treatment may involve inducing vomiting to remove the toxic substance from your dog's system and providing supportive care, such as intravenous fluids, to maintain hydration and support kidney function.
