We all wish they could talk, thug. The pup here could tell me what he did with the last TV remote, which disappeared from the house (it's probably in some hollow in the garden!). Did your present dog know the previous one? I'm wondering how long the scent lasts, too, from when made to his first finding the place.Possibly a very long time if the place is sheltered from the elements, more so if the scent is strong from a dog 'marking' the area.Maybe he recognises the excavation as the work of a dog. He's waiting for the workman to clock on again !
It's nice story, and intriguing because,try as we might, we can't think as a dog !.
