Raisins and grapes are toxic to dogs and can cause kidney failure? Who knew? I never knew. My dog goes after my kids' raisin boxes when they leave them on the table when they are done. I don't know how many raisins she's actually consumed, but they are bad for dogs. Just thought I'd pass that along. Bloodwork and urinalysis were done...we'll get results tomorrow. Vet seems much more optimistic today than he was a few weeks ago.
