I would have thought they have better eyesight than that, it seems dogs spot incoming ducks as good as we can
Bollocks, I say ...
Movement they detect better than us. They also have hearing and smell beyond our capability!Quote:

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.

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.
If the dogs eyesight was that bad how would he find the ball?
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.Quote:

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.Quote:

Now explain how their taste receptors transmit the taste of arse and other dogs poo as delicious, and you have yourself a Nobel Prize
Yeah I'm on the fence, I have had occasion where the dog sees something and knows what it is from a great distance ( prey ) Like paddling out to a duck 250 M away and then I have occasions when the dog cant find me in a open field untill i wave my arms .
A mates GWP (sadly gone now) used to spot incoming birds such as starlings when they were all but invisible to the human eye.
This thread is interesting. It shows how widespread a general lack of understanding many have over how a dog works and operates. That a blaze orange dummy is that color for the handler would be one of the most basic things I would expect ANY basic dog handler to know. All of the examples given of things dogs can see have been moving. Anyone who has recalled a dog while being in a group of people having trouble identifying which is their handler on return unless there is a wind from behind the handler. Most handlers in this situation will have to extend their arms and repeat the recall just so the dog gets a recognition.
The better you understand these aspects of your dog, the better you will handle your dog. The more you try and believe the dog thinks, acts, sees, hears and smells like you do you are putting up impediments you don;t need.
Arm signals involve movement. They see that really well.Quote:

it means he,s heard it and trying more likely to bring his snout first then his eyes maybe onto the job.
maybe turning to it helps cross reference the lugholes to.

A Lab can only see food. Everything else is irrelevant.
Our dog used to catch flies mid air, using ears and nose alone would be something alright.
I realise that most things posted on the internet are 100% correct and reliable, but I would still like to read the research that this video is purportedly based upon. I am not sure that this is a correct representation. Dogs, like many mammals have dichromatic vision. This means that they do not possess all of cones in the eye that we do. The cone that they are missing is the one that is sensitive to longer wavelengths such as red and orange. Similar to someone who is colour blind they have trouble distinguishing between middle-wavelength light (which includes green) and the longer wavelengths (red and orange). What they do possess are the cones sensitive to short-wave length light which includes the blue portion of the colour spectrum. While we can't talk to dogs we can talk to people who are colour blind and they see clearly, albeit with a limited range of colours. A study published in the journal for the Royal Society for Biological sciences in the early 90s showed that colour blind people (who have dichromatic vision) performed far between than people with normal vision in identifying camouflaged objects.
When I am training a dog I will often hide from them. When they are young I can hide from them in an open field. I just lie on the ground. But as they get older they find me quickly and can even find me reasonably quickly in heavy cover. I take from this that the dog's eyesight is not getting better it is just that they are learning to use all their senses. So while we think that they see us they have probably just smelt us.
I think the video is a screw up, technically if your alright on video editing you could tweek the colour fields and get it way more realistic.
They don't see in colour as we do so why not do the job properly?
With those colour changes clarity will change. That's just an out of focus mess that's NOT a real representation.
Movement? They see that better than you!Quote:

A few staples and some TLC and she is well on the mend
Lucky wee dog ...
I have stellar vision Gibo. In the dark at night I can even see distant stars that are gazillions of miles away.Quote:
