What does her diet consist of? If she gets any human food this could be the cause. If she gets rawhide chews it could cause it. Also a very likely cause would be parasites. If she has not had a stool sample checked for worms I would have this done. If this is good keep a record of everything she eats and see if you can find a correlation. Does she eat things like pine cones, etc.?
