    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!

    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.

    It takes 43 muscle's to frown and 17 to smile, but only 3 for proper trigger pull.
    What more do we need? If we are above ground and breathing the rest is up to us!
    Rule 1: Treat every firearm as loaded
    Rule 2: Always point firearms in a safe direction
    Rule 3: Load a firearm only when ready to fire
    Rule 4: Identify your target beyond all doubt
    Rule 5: Check your firing zone
    Rule 6: Store firearms and ammunition safely
    Rule 7: Avoid alcohol and drugs when handling firearms

    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.

    There is an old boy of a Golden Lab that I meet at the beach most days. He is totally blind, and fairly deaf, but he finds his ball, or a stick thrown into the sea. It takes him a while, but he always finds it

    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.

    I'm not buying it even for two dollars.....my old half deaf half blind dogs could still follow a ball threw the air. (Made them stay at heel until released )

    my cocker is nearly blind due to faaarked up breeding (dont get me started) even on his good day a dead duck on water is fairly safe if more than 50 yards away....chuck a rock in its direction to give him a clue and his nose will take him the rest of the way.Ive seen heading dogs spot pigs at 6-700 mtrs but they had clues by us humans watching them,and come to think of it you can give arm signals from a long way away too.

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