same as blue eye sled dogs(with the old traditional mushers)

lovely dogs Moobli

benmcf... wall eyes..is no pigment..bi-eyes is of different colour and you also get split eyes too.

Ok every site I have ever read lists "wall eye" as being one blue and one brown/amber eye.

From here: http://abnormality.purpleflowers.net/genetics/eyes.htm

"Wall eyes are when a dog has one blue eye and one brown or amber eye, and a split eye has some blue in it and the rest is brown or amber."


That's how I've always read it. Blue eyes are just blue eyes. Wall eye is when one eye is blue.

oh are you still on dial up? cos the sites got music, takes ages!

Can you go to the home page, maybe see her on onne of the group pics., Shes B&W with lots of freckles!

i promise u..collies have no pigment sibes do.... i went to see the eye specialist with my collie and one of my sibes... both have bi-eyes..she was sooo happy i was there as it was student day,and she asked to use my dogs to show the students the difference..and both with a brown eye too.
(my collie is bi eyed with a split eye)

It's connected to the white spotting pattern that gives BCs their markings. the white patches are where pigment has not been allowed to develop at the embryonic stage. If a white patch happens to fall across the eye, pigment can't develop in the eye either giving a blue eye. Even though it looks like there is a coloured patch over the eye, it still means the pigment granules didn't develop in the eye.

The same can happen to a lesser extent in Dalmatians - my friend's Dalmatian had one eye which was partially blue and being interested in genetics she looked into why it had occurred.

It can sometimes also happen in cats - bi-coloured cats can have one normally coloured eye and one blue eye!

Merlin's dam was a working BC with very little white on her face, just a small streak, but she had one blue eye.

In Huskies the eyes are caused by a completely different gene, one which affects the pigment over the whole body, regardless of any white markings. This dilutes the pigment in the eye also and turns it to blue.

A chinese crested gentics site says it can be both blue, or just bits of blue in the eye.

Yes that is what I am talking about,On the first site it said it was possible that collies also have this gene - although rare
I understand the other reasons for the lighter eye - I was asking if anyone knew genetically if collies actually have this gene too


I have also hear that shepherds like one blue eye one brown sometimes but I think really lots of people just like a dog that looks a bit like their last really good worker - and as the most common colours in collies is balck and white with brown eyes then more farmers will have had a good dog looking like that and so will favour it more

Yes, still on dial up I will have a look at the home page and see if I can spot her, thanks.

I think you do find that a little, although most shepherds are interested in how the dog works (or how its parents work or are bred) than how it looks. My hubby (like me) has a preference for rough coated, black/white dogs. However, we have more bare-skinned black/white/tan at the moment, simply because they were the ones who turned out the most promising from the last litter.

I keep meaning to ask, do you still want the alpaca wool?!

My older shepherd friends always call the blue eye the distance eye !!

It's only a fault in the KC breed standard because the Australians don't like them & the UK breed standard is based on the Australian-the same as the amount of white on a dog-my Keewee is white & black like her dad, who has no trouble working sheep ! Her full sister out in Australia is also a top worker !
