dog biting ankleto persistently remind someone or a group about his or her responsibilities in a mildly unpleasant way but without acrimony; evokes the behavior of a small yippy dog that nips at one’s heels annoyingly but is generally harmless, or a sheepdog herding animals; a similar term with more whimsical connotations is tickle, as in “I’ll tickle the group for that feedback tomorrow morning if I haven’t heard from them by then”
