Thread: Dog vision. Interesting simulation.

I would have thought they have better eyesight than that, it seems dogs spot incoming ducks as good as we can

Movement they detect better than us. They also have hearing and smell beyond our capability!

Bollocks, I say ...

You would, you think they are human!

I m pretty sure they see way further than that. I thought they were going to change the color spectrum of the movie, then that would have been more what a dog see.
Dog recognise a familiar humane face from 20 m away easily at least for sure.

Now that I know they see fuzzy images I will never stop still and bob all over the place in front of my Great Danes and confuse the living shit out of them. Ha ha ha ha gotta wake them up first.

Awesome couch potatoes.... the big hound breeds all the same

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

Reading from Stephen Budiansky's book The Truth About Dogs he writes ... A study of about two hundred dogs by veterinarian Christopher J Murphy and his colleagues ... studied several breeds of sporting dogs, such as Chesapeake Bay retrivers, golden retrievers, Labrador retrievers, cocker and springer spaniels were on average a bit farsighted...but two-thirds of rottweilers and half of German shepherds and miniature schnauzers in their study were significantly myopic.

Which would suggest that the degree of lack of focus on the above video is too much of a degree.

Relating to colour blindness in dogs ... he writes ... a practical consequence of Neitz's findings is that many of the things we make for dogs are the wrong colour. A bright red-orange dog toy stands out dramatically against the lawn to us, but to the dog its colour is not readily distinguishable from the green of the grass at all. A violet object would probably be a much better choice when the background is green.

So the hi-viz of a standard dummy could be accepted more for the dog handler than the dog,,,

Some more from Budiansky...dogs can hear sounds up to about 65,000Hz or cycles per second ... a healthy teenage human can hear sounds up to a maximum of about 20,000Hz ... the canine nose has something like twenty times as many primary receptor cells as the human nose.

And by the time you're 50 you're probably down to about 12khz top end, maybe less if you have punished your ears with noisy things over the years.

Same for your dog If you punished his ears with years of duck shooting and deer hunting.

Hence why hunting breeds were developed to have folded ears ... and to protect their ears in the rough conditions they hunt in ...

Cut it out. Dogs had folded ears long before they were even used in sporting pursuits.
