After a dip in the beach waters
Dogs in general seem to get fascinated by the forward and receding movement of the waves accompanied by the roar of the water as it connects with the shoreline. Either they simply don’t understand the continuous movement or mistake it for an invitation to play. You can see them racing along the beach barking loudly at the waves or digging away holes in the sand or rolling on their back. This dog seemed to particularly enjoy its time in the water and time and again would shrug off the excess water and sand, only to get back into the water again.
