Grapes and raisins are bad for dogs because one of the most serious complications if they eat them is that they can cause severe kidney damage leading to sudden kidney failure with lack of urine production.

Grape and raisin poisoning will usually cause dogs to develop some combination of the following symptoms:

• Vomiting and/or diarrhoea – often within a few hours of ingestion. Vomit and faecal contents material may contain pieces of grapes or raisin.

• Loss of appetite

• Lethargy, weakness, unusual quietness

• Abdominal pain

• Dehydration

• Oliguria (passing only a small amount of urine)

• Anuria (complete cessation of urine)

• Foul breath

• Oral ulcers

• Tremors

• Seizures
