Anal glands are scent glands situated on either side of the anus. They are usually emptied of their secrection as the dog passes a motion. They can become blocked if the dog is fed very soft or low fibre food. If left untreated the secretion can become infected and painful in the extreme. Get your vet to check them and show you how to express them. It is an easy process but must be done properly to avoid stress and injury to the dog. I think it is unlikely in a four month old puppy though so get your vet to check the worming treatment you are giving the pup too.
