Usually it means a trip to the veterinarian for a dewormer since you don't mention anything else. Your just about ready for your first vaccination and deworming so make your appointment. It could also be you feed her well or a combination of the two ;-).You can also ask them your questions and sometimes it helps to write them down as you think of them before your appointment so you don't forget. If your pup seems in pain or acts unusual and has a big belly it's an immediate trip to the vet.
