In case there are other dog lovers who are not aware that raisins and grapes are toxic to doggies, they most certainly are.
My daughters beautiful black lab Rufus ate a half of a bag of stolen raisins Saturday night. She upchucked Sunday, and when it didn't stop they took her in to an Emergency Vet. None of us had ever heard raisins were toxic to dogs, but they are: they take out the kidneys.
