We've done a liver to liver mating, but made quite sure all the livers that we knew in the pedigree were a lovely rich 'conker' colour. All the pups inherited a good colour, and they don't bleach in the sun. They do, however, have a shorter coat than other livers , but that's not necessarily a bad thing.
I doubt that our present mating of black carrying liver x black carrying liver will give a darker colour than our own liver to liver, but time will tell.
I think that if the genes are there for a darker colour, there is no reason that it should be diluted, but so many folk that have been breeding livers for longer than I have will tell you it's wiser to mate black carrying liver to liver.
Think I wouldn't intentionally risk Providence by repeated mating liver x liver.
However, it must be emphasised that we never, ever breed for colour as the main feature - other factors which are more essential for a well-balanced working dog are more important.
