Grapes and their dried fruits can be incredibly toxic to dogs and cats, and ingestion of a small amount can be enough to cause kidney damage. It is not fully understood how these foods cause poisoning, and there is no correlation between the amount eaten and the likelihood of an animal developing complications. This means that even a small amount can be enough to cause serious kidney impairment.
Signs of toxicity include:
Vomiting and diarrhoea
Abnormal drinking or urination
Weakness and lethargy
If your dog or cat has ingested grapes or their dried fruits, contact Animal PoisonLine on 01202 509000. Veterinary professionals can contact VPIS on 0207 305 5055 for detailed treatment advice.
