Puppy with diarrhea

Question
We just got our 11 week old English bulldog on Tuesday. She started with diarrhea on Thursday just once or twice a day its not alot. She is eating pedigree puppy food and doing good should I worry?

Answer
Diarrhea is common and may or may not be a problem.  It can be as simple as a sudden change of food and water.  If she isn't starting to firm up by Monday, I wold see a vet.  There are a number of parasites the vet can easily identify and then clear up.  Any sign of a lack of energy, and you need to contact a vet immediately, it could be parvo.
