A mere 48 hours after the event, little dog was acting like nothing happened :thumbsup:
Hopefully (keeping thread on track here) she will make better use of her eyes around vehicles, in future.
what a load of bollocks. Where are the research links to back up the claim they have such poor resoution at distance,.
It's a fairly natural reaction Headcasee when your experiences with dogs, based 100% on how you see the world would find some of this hard to accept, primarily because you not in possession of the information of how they do work. When you actually understand the animal better, you train it better and the dog is more relaxed and accepting of lessons.
Here is some back ground information on that specific video.
Published on 23 Dec 2013
This is a rough simulation I rendered through the eyes of a dog. A dog's eyesight is very limited to color in respect to what we see; they can see (a lighter shade of) blue and yellow, but cannot distinguish red and green. They also have a visual acuity (contrast) of much less detail than we do. It is believed that most dogs have an eyesight equivalent from 20/50 to 20/75, however they have been known to identify their owner at a range of 800-900 meters due to their ability to visually discriminate motion (impressive)!
BTW, this is my Labrador. His name is Wilbur!

Dog Vision filter details:
(Photoshop CS5 - rendering frames from original video)
Channel Mixer values
Output Channel: Red
R= +32%
G= +85%
B= -17%
Output Channel: Green
R= +25%
G= +68%
B= +7%
Output Channel: Blue
R= -1%
G= +1%
B= +100%

(PowerDirector v12)
Visual acuity filter simulated through a configuration degree of "4" in the "Blur" effect filter.
Brightness effect reduced by a factor of 20% (this, however, does not account for lighter color tones, since there is a relative measure of brightness-detection with dogs due to their tapetum lucidum [a layer of tissue in the back of the eye which reflects visible light]).
(Video to Picture Image Converter)
Extract still frames from original video footage (.mts) from my Panasonic Lumix TS4.
(Photo Lapse 3)
Convert the edited images back to high-quality .avi format
For some reason, the recompiled video was slower, so I had to modify the length of the edited video to match the original.
Thank you for watching! As time progresses, so will my videos. Enjoy!

But let's look at the same information differently.

Before you jump and decide to make an internet dogs breakfast of a seriously important aspect of dealing with dogs... just think about this, and then think about how now knowing the strengths and weaknesses of your dogs vision how you will now be able to discern when they are using scent, or movement, hearing, or can see ducks after dark, or can't see something 20 feet away that is red..... The impact this knowledge makes is significant, but may seem subtle at first!
As you probably assumed... I'll have more for you. :D
I cant believe that all breeds have the same degree of binocular vision, purely based on the fact that there are all manor of different eye placement across the breeds.
why the bollocks doesnt the delete not work on this site. i have to eat humble pie. did some research and they doo have Jamisons vision.
I reckon certain breeds would have worse vision than that.

however one small cat treat (5mm max) he can grab out of mid air.
sense of smell, well he can detect a pot smoker really quick, we think his last bastard owner smoked it then starved him and beat the crap out of him.
i dont know where the dislike of burkas came from, maybe he hates the smell of explosives
There is a 2013 documentary called A Dog's Life. It looks at how dogs perceive the world. It has been a while since I saw it, but I think that the researchers in that documentary concluded that dog vision is quite nuanced and the current theory is that is varies quite considerably between breeds. They think that some breeds are more short-sighted, while others are long-sighted. This may explain why your dog was able to see you at a distance (without waving), but struggles to see you amongst a group of people at a relatively short distance. It also tends to suggest that the render in the youtube video is at best inaccurate.
To try and resolve the issue once and for all I asked my dogs this afternoon whether they had blurred vision. They just said that they had been wondering the same about me after my shooting display the other day.
:D :D :DQuote:

One of mine told me he did have blurred vision, but that one is a bit of a wanker! :DQuote:

See like a dog and my Lady reckons men are just like dogs.
Makes a change from being called a pig etc. :D
Reminds me of the story of the drunk who comes home from the pub holding a goat. He walks into the bedroom and announces "This is the pig I've been screwing"!
His wife laughs and says "It's a goat you drunken fool"
He replies.. "I wasn't talking to you"!!! :D
