Raisins, and possibly grapes are toxic for dogs! A Basenji here in Dayton died after eating about a 1/2 cup of raisins. He was rushed to Ohio State Veterinary School, but there was nothing they could do. The Vets at Ohio State said that Raisins are toxic. This was also written about on the ASPCA's website. It is un-clear about grapes, but I'm not taking any chances!!!!

I have heard that green beans are good for dogs, especially those on diets!
