German Shepherd Dog Coat Color: Dilute German Shepherd Dogs

I am really lucky to have some good dog lover pals around me. Yes, most of my peeps are dog lovers and some of them are specifically German Shepherd lovers. Rizia Robertson is one such friend of mine who seems to have given her heart to German Shepherds. During my last conversation with her, I told her I can talk about dogs for centuries without even getting tired. She said, “well you have a friend here who loves talking about dog – especially GSD”. Are you wondering why I’m talking about Rizia? Well guys, I just want to let you know that she has been the first one to inspire me to write about gene dilution in German Shepherd Dogs. My last post on Gene Dilution in German Shepherd Dogs was written being inspired by Rizia. Truth be told here… I had written the article on GSD gene dilution for blue and liver pigments some times back in 2007, but never published it until I felt the urge post it after having days of discussion with Rizia. I would like to thank her because of this. Rizia, let your love for German Shepherd Dog never stop!

This is again another piece of information about German Shepherd Dog gene dilution. Regarding German Shepherd Dog coat color the SV breed standard said, “the color of the GSD is in itself not important and has no effect on the character of the dog or on its fitness for work and should be a secondary consideration for that reason. The final color of a young dog can only be ascertained when the outer coat has developed.” It is hence, beyond all controversy, that amongst all undesirable factors in the GSD breed, the coat color is the one that should be included as the last point in the list. My personal view is that if the coat color doesn’t affect the working ability of the breed (which the breed is actually meant for), it should be excluded from the list right way so that the two mutations of black gene in the GSD: blue and liver are not considered to be faults in the show rings. GSDs have two pigment genes: melanin/ eumelanin (brown/black) and phaeomelanin (yellow/red). Melanin is normally black, which has two distinctive mutations in GSDs – blue and liver.

As per the standard the blues and the livers are genetic faults, and no reputable German Shepherd Dog breeder will breed these so-called faulty genes. The GSD breeders, who breed these genes, with both parents as carriers, end up with a shallow genetic pool. In most cases the liver and blue puppies usually come by accident. Frankly speaking, I haven’t yet come across a breeder who breeds to produce liver and blue pups deliberately. But here, again the same thing, I would like to say. If the color genes don’t affect the working ability, character and behavior of the breed, what’s harm in livers and blues? This is a very debatable question and I won’t go in for arguments and debates, nor would I like to criticize any bloodlines. I would rather say that diluted dogs may descends from high quality specimens from top bloodlines that have proved even in the Schutzhnd trial fields.


Just a gist about Blue and Liver genes in German Shepherd Dogs

Blue Gene in German Shepherd Dogs

• Double recessive color gene
• Rare color
• Dilute gene, which means it dilutes the black pigment in the dog.
• Considered a disqualifying fault by the AKC.

Liver Gene in German Shepherd Dogs

• Double recessive color gene
• Rare color
• Dilute gene that blocks the black pigment in the dog.
• Considered a disqualifying fault by the AKC

Gene Dilution in German Shepherd Dog – Blue and Liver Dilution

Blue German Shepherd Dogs and Liver German Shepherd Dogs

The blue and liver GSDs had been the rarest genes once upon a time that have always captured breeders’ attention. Fortunately these genes are not as rare as it used to be some years back. The search volumes for the blue and liver GSDs in the Internet have been on a rising, which is gives an indication that people are looking for these genes more these days, either for puppies or to get information about the blue and liver German Shepherd Dogs. There are actually two possible dilutions for the black color in German Shepherd Dogs - “Blue Dilution” and “Liver Dilution”. Here’s just some information about these rare German Shepherd genes – the recessive blue and liver gene.

Colors of these German Shepherds are different from the regular ones that we usually see in the dog shows. They are real striking in appearance, if bred correctly. If not bred well, these dilutions usually come with blues and brown nose, while the standard requires the nose, nails, eye rims and lips to be black strictly.

Patterns of Blue Dilution in GSD

The blue gene in German Shepherd Dogs actually turns the pigmentation of both skin and coat into bluish or steel grey, which is usually very dark. The tan area, on the other level, remains almost the same tan markings as we see in regular shepherds. Sometimes the tan ground may take a faint silvery tint. In the German Shepherd Dog breed, there are great chances of the blue gene to occur in any pattern and type of coat. This finally dilutes the black pigment.



Patterns of Liver Dilution in GSD

The liver gene affects the dog’s pigmentation in almost the same way. The liver gene in German Shepherd Dogs dilutes the black pigment, thereby turning both the coat and skin into liver brown color. Like the blue genes this also dilutes the eye pigmentation by giving the eyes a wrong tint – silvery-yellowish-brown color. The liver gene can come in any pattern alike the blue one. The tan markings seem almost the same as in the regular GSD.

In either of the two dilutions the dog looses it black pigmentation, which is replaced by either blue or liver pigments. Remember the gene that gives color and the gene that gives pattern are two distinctive genes. This ensures a good chance that either dilution can come with three different patterns, viz. solid color, two-toned pattern and agouti. Both these dilutes in German Shepherd Dogs are seen with two-toned pattern and agouti, more commonly than with solid colors. Solid blue and solid liver German Shepherd Dogs are rare of the rarest genes in the world. In most cases the liver and blue German Shepherd Dogs comes with liver-brown and blue noses respectively. Both these gene dilutions in German Shepherd Dogs affect the eye pigmentation too!
