Thread: Dog vision. Interesting simulation.

Just thinkin about the old ridgey I had .... one day I caught him on the deck in the back yard peering round the side of the house , his head nodding away .... up and down up and down . Upon investigation there was a kid on a tramp across the road on a rear section behind a fence at least 100m away ,, up and and down up and down.... he also used to watch planes in the sky at so many hundred or thousand feet...... but I guess his hearing pointed him in that direction first
