There are a couple of reasons... maybe there is something wrong with that pup. Usually, however, if there is a pup who has something wrong with it, Mom just pushes it aside and doesn't encourage it to nurse like she does the others. OR maybe she is a bad mother. There are some dams who truly are NOT good mothers. If you feel the pup is healthy, just take it away and feed it yourself. Then if it thrives, when it is a little older put it back with the litter (with lots of supervision)and see how she takes care of it.
