Digging

The dog digs without any clear purpose. Some dogs may turn quickly while digging and try to catch the soil/sand that they are tossing in the air with their front paws.
(Timbergen, 1952; Hubrecht et al., 1992; Pageat, 1998; Beerda et al., 1999)

This Belgian Malinois is digging in the sand, completely absorbed in what he is doing.
