I have a Lhasa poo and her vet has told me the lhasa apso breed have very sensitive stomachs. She has had this problem several times and it's been caused by anything from flea and tick treatment to introducing a new type of treats! If it's been an issue for a few days, you really should take her to the vet. Dogs can dehydrate easily and they can give your dog medication to clear up the problem.
