Always wondered how the “experts” came up with that theory.

It’s not like the dog can communicate the information to them.

They can look at the retina under a microscope and see that dogs’s eyes only have two types of cones, whereas humans have three. This means dogs can only break the perceived light into two bands instead of three, giving them a smaller range of colour perception. This can then be tested using coloured indicators and food to determine whether the dog can distinguish between certain colours.

Conversely, dogs have more rods than we do, which gives them better night vision.

Of course we also realise that dogs have far superior smell sensitivity than us mere humans, which begs the question of their choice of items to roll in.

I printed it off and showed it to about 15 feminiles at work, only about 3 got it.

Still doesn’t explain how the experts come to the conclusion that dogs are colour blind 😜
