THE EYES HAVE IT

We have been wondering whether Franklin's eyes see the same things that we do.

After wondering aloud for a very long time I did some research which indicates that the answer is yes and no. Such is the result of a lot of research. Nothing definitive.

But there is a lot to know about dog vision, nonetheless. Yes, he sees the same stuff without distortion but he sees it differently: he does not see much of the red spectrum (but he is not color blind, as commonly believed); he sees wide-screen--way over 180 degrees (not all dogs do, it has to do with the length of the nose); he sees much better in the dark (more rods); and he can detect movement faster than we can(his flicker is quicker).

All this at various sites.
Dogs are streakers; Dogs are not, well, red; Doggy nights; and even MORE than you wanted to know about dog eyes

This should all explain why, when we tell Franklin to look at something, he usually does not seem to 'LOOK!'. He has already seen it; unless it is pure red of course, then we are performing a service for him.
