Liver/Brown Coat Colour Genetic's Simplified.
The B series/locus gene, BB(Black) is the most regular type, Bb(Black carrying brown)
the next is bb(brown).
Then we have phenotype and genotype simply "what we see" and "what is hidden".
Both are inherited from the parent,so the GSD shows genes and hides genes for colour.
4 main colours are involved in determining what color a German Shepherd dog will show.
The Liver/Brown colour gene is regarded as a recessive gene the genetic code for this colour is bb.The liver colour is amongst one of the more unusual colours found in the breed as it is hidden as a recessive until 2 carriers meet.
Even when this happens only a small percentage of the litter from 2 carriers will be liver/brown coloured.
Both parents have to carry the colour to produce it,not all dogs carry the same colours.
If you see a liver/brown coloured dog you can say that dog is dominant in the colour "liver/brown" because it is liver/brown but when mated to a different colour carrier dog the colour becomes recessive"hidden again" and no pups will be liver/brown from the resulting litter.
bb are color genes which block black from forming,it does not dilute black,brown is a naturally occuring colour in the GSD which has occured over and over but the pups have been culled from litters of show breeders because of false accusations associated with the colour.It has been proven just because a GSD is liver/brown colour does not determine what if any health problems it will have, it is possible it will have the exact same as any other colour gsd is likely to have.
The bb is recessive to BB (Black )and Bb(Black/liver/brown) carrier.
The liver colour comes in different shades too,recently i have seen a very dark shade of liver which was like Plain chocolate color and more recently i have had the pleasure in producing a very light milk chocolate color pup... is the best way to describe the colour but powder liver/brown may be more appropriate.
A liver/brown dog will have a liver/brown nose,eyerims,lip's and pad's,these will be pink at birth and darken as the pup matures.Eyes can start from bright blue or grey then develop green or amber usually by maturity eyes are hazel to dark brown much depends really on the depth of coat color.
The dog will have Brown looking hair of various shade, no black at all anywhere on the coat or skin pigmented areas on the entire body including inside the mouth.
GOOD NEWS SEPTEMBER 2010
The colour Liver can be registered again, and is a recognised colour with the Kennel Club of Great Britain.
BAD NEWS >>>Pattern not reinstated<<<Which means if your dog has Gold/Tan/Red, legs, it will not appear on the registration papers<<<totally ludicrous as Gold/Tan/Red legs can be registered in any other colours.
Liver colour dogs can be shown in the ring but the colour has not yet been welcomed by the show breeders so it will be a challenge to achieve full equality of colour for a while to come i expect.
Liver German Shepherds can do anything a black/tan German Shepherd dog can do.
This Colour does not effect ability.
The liver colour is not known as yet to cause any health problems.Any GSD of any colour can have or develop health problems.It is documented that the GSD is predisposed to 132 Genetic diseases!!"gasp"so why you ask do people breed the gsd at all? it is because the gsd is without doubt one of the best versatile dogs known to man!
It is because a huge percentage of gsd's live to a ripe old age without life threatening problems!
It is because if we dont, they will become extinct!
So why should you breed a liver german shepherd dog? ??? Why not? Do you get a choice of colour when you look at other breeds? yes you do! other species?yes you do!
So the choice of colour in the gsd is now becoming available, thanks to the decency of some breeders choosing not to murder them soon after birth.Not everybody wants to show their dog in a ring, many people want a gsd for working trails, obedience competition and other dog related sports, pet owners much prefer the colour of their own choice and the colour is certainly eye catching.The choice is available for anyone who prefers the unusual, however there are not many readily available.
Regardless of colour it is up to you to make sure you get a gsd from someone who you meet and feel comfortable that you can trust, that they have their own dogs and pups well being at the centre of their breeding,and that if you have a problem they will do everything they can to help you with it.
Do not make assumptions on a litter of this colour of german shepherd dog because of what you read on internet forums of biased colour descrimination opinion, they are often full of bullies who hide behind computer screens.
When coming to visit your prospective puppy ask as many questions as you can,write them down and bring them with you so you dont forget to ask something.
Colour discrimination is againgst the law in humans,various other breeds include this colour in the standard,cows horses sheep cats etc are naturally this colour but liver german shepherd pups have been "(murdered)culled" by ignorant breeders in the past, which is why the colour has only started emerging in any quantity.
Hopefully we will see a re-emergence of the colour and the liver gsd will attain equal status.
Incidentally some other pedigree dog breeds,describe this colour as chocolate,which i have to say is a much better way to describe it as there are different shades.
If Galaxy was a human her colour would be classed as ginger,awburn, red head, strawberry blonde,medium brown,brunette and numerous other names.It is just a colour a natural occuring colour..
