The advice I've heard for treating diarreah is to feed them nothing for 24 hours, then feed a bland diet. Boiled chicken and rice is one popular choice. It's important to make sure they are well hydrated.

And, yeah, I would think eating strange things could do it. I've got a lab that runs into the same thing a lot.

Try teaching your pup a "leave it" command. On leash, walk by something they want and say "leave it." Don't allow them to go near it. Keep practicing. It's an important lesson.
