Poor Molly.

Hope the vet can find out what's wrong with her. It could be stress like everyone else said. I recently read in one of my dog magazines that plain 100% pure canned pumpkin is incredibley effective in dogs with diahrea. It said to add a teaspoon or two to the dogs food or feed it straight. Sorry, it didn't say what size dog should get that amount though.

Let us all know how Molly made out at the vets today. Feel better soon, Molly.
