Colour blindness


Recommended Posts

Me and a friend usually go out lamping together...he slips the dog and I work the lamp but I always find he has a nack of seeing the rabbits I pass over and sometimes I won't see the ones he's on about til I'm right beside them, it seems to be worse when the grass is turned yella.... I have decent vision so I was thinkin it's just my colour blindness (which isn't severe atall, just light shades of green and red)anybody else colourblind find this happening, especially on the lamp because I'd miss a shite load of rabbits if he wasn't with me.

At one time it was thought that all dogs were colour blind, but modern thinking has changed, but, "they do see color, but their chromatic acuity is significantly less than humans'. This is for two reasons: (1) dogs have far fewer cone cells in their retina (cone cells are responsible for seeing color); and (2) dogs are dichromatic (they see only two primary colors - blue and yellow) whereas humans are trichromatic, meaning we see three primary colors - red, blue, and yellow.

Humans have 7 times higher proportion of cone cells than dogs, meaning that when dogs do see colors, they are pale or faded. However dogs have a much higher concentration of rod cells, responsible for seeing black-and-white, and also much more sensitive in lower light conditions. For that reason, dogs have much better night vision than people"

The topic was about people but I know what you mean about dogs having better night vision, one time my dog came back from a missed run and was just back on the slip and he started pulling behind us in the pitch black, lamp on and a rabbit sitting out fro a place we had walked across not 2mins earlier. This one wasn't missed :D

It could be worse lads you could be out with someone who puts the lamp on the dog rather than what its chasing :whistling:

or someone who takes about a week to slip his dog when the younger dog is running on its own ,dont think he wanted his dog to get there first :whistling::whistling:
