According to http://www.sciencenet.org.uk/ , dogs do not see in black and white, they have colour vision similar to red/green colour blind people. They only possess two of the three types of core (colour sensing cells in the retina). There are three types of cone: blue, green and yellow (often called red). Dogs only have blue and yellow and the yellow core detects yellow and red. When the yellow gets stimulated it signals either yellow or red, the yellow when mixed with signals from the blue receptors will detect green. Therefore dogs can not detect the difference between red and green.

My aunties dog used to have a strong passion for the colour purple. He would always sit on purple cushions and rugs and run up to people wearing purple clothes and find purple things to play with. My mums dog once got lost in Barnsley market, my gran at the time was wearing a green coat, Simon went up to every person in the market wearing a green coat to try and find my gran.
I think the notion of dogs being colourblind is ridiculous, why would any animal that depends upon it's eyesight be naturally colourblind.

Yes, they do only see in black and white, but its not really colour blindness as such. they can distinguish the different 'shades' of each colour and combined with there amazing sense of smell and hearing they are actually more equiped to deal with the big wide world then we are.

I used to think that, but just the other day I heard a vet talking on tv, saying that yes, dogs CAN see colors, but not ALL colors.

Dogs do not have the same range of colours as us they can tell different shades apart quite easily and the can see primary colours.

Mine can only see in black and white - but then again I'm on benefits and can't afford a colour license.

No, Scientist proved that a dog can see is color. But not the same color as we do. Like when they see orange, they see yellow and red, not orange.

no. it was thought, in the past, that this was true. but recent studies have shown that dogs can see can see almost all the colors we can, except red and green.
