A close encounter

Photographing, or at least, had been photographing a mother and her two cubs until they returned to their holt. Whilst waiting to reappear this dog turned up on the scene. A brief sniff at the holt entrance  was met with an abrupt send off by mother.
He continued on, following the shore some 40 yards to in front of where I was hiding amongst the cover of some boulders. Without knowing I was there, he landed right infront of me on the shore, took a few steps up the beach where he sprainted then continued along his circuit of his range, seemingly unaware I was ever there. It was typical of such a close encounter, when your out of site and scent, when their eyes feel like they are right on you but yet they don't actually see you. He ended up too close to focus with my 500mm. I just sat tight and stayed silent.
