Well, this is chapter is over. Sammy's kidney values 72 hours after eating the raisins were fine, so he is in the clear. All that's left is filing the insurance claim.
My neighbors have a dog who will eat anything. He's had several surgeries to remove socks, plastic bags, rocks, etc from his stomach.
Luckily Sammy (usually) just chews things up and doesn't eat them.
