what are the required eye colours for labs as i have a yellow with green eyes and some one pointed out they should be a hazel colour .Thanks in advance

The Breed Standard is very clear.

Green eyes are not acceptable.  Would be curious as to the colours of parents, ie choc to yellow mating :(

How old is your dog?  If it's still a pup may have time to change.  Our Spanish some of which have hazelish eyes can still be quite green for the first 12 weeks but then they change.
