this can be normal. a hard dry stool can form an intestinal plug or "dam" of sorts. there can be more liquid stool building up behind it so when you pass the hard stool you have essentially broken the dam. since i do not know anything about you or your medical history if you have any concerns about this change in your bowel habits it is best to discuss it with your medical provider --- someone who knows you your medical history and has the ability to examine you or order any appropriate diagnostic tests.
