David Bowie has got one blue eye and one brown eye .....
Well, I know he's a bit strange, but he is definitely a one off and no-one will forget him!!
I would guess that with your baby it is simply a pigmentation glitch, and it makes him so much of an individual ..... everyone who meets him will never get him confused with any other Cockers will they !!
Bramble has quite 'milk chocolate' coloured eyes as opposed to Barley's dark brown ones. One of Brambles eyes has an area of darker pigmentation (just a little splotch really) but it all means that he is an individual!
I will be interested to follow this thread and see if anyone else (apart from Collie owners, that is!) have dogs with different coloured eyes - it may well be that his blue eye will change over time, and then won't you be disappointed !!!
