Grape and raisin toxicity in the dog is a potential health threat to
dogs that have eaten
grapes or
raisins. It can cause the dog to develop
acute renal failure (the sudden development of
kidney failure) with
anuria (a lack of urine production). The phenomenon was first identified by the Animal Poison Control Center (APCC), run by the
American Society for the Prevention of Cruelty to Animals (ASPCA). A trend was seen as far back as 1999.
[1] Approximately 140 cases were seen by the APCC in the one year from April 2003 to April 2004, with 50 developing symptoms and seven dying.
