i have a black and gold gsd bich and i have gone thourgh her pedigree and all of her granddparents are mainly white but her both parents are blck and gold what are the posabilities of breeding my bitch with a white dog and getting a mixed litter. please help.

If her parents both have a white father or mother, then there will be a strong chance that you will get a mixed litter.

Just to add also Just because the gparents are white doesn't mean that they don't carry other colours, all depends on which gene each pup took from each parent, her parents will both carry white. My white boy is all white breeding back 5 generations but he still carries the gene for black and produces Sable. I'm afraid the only way to know for definite is to put her to a white cos even if you put her to a dog that carried white and she didn't have a white, it doesn't mean she won't be a carrier. Genetics are complicated eh ;) even harder to explain.  But if you don't want white you will probably get it :) White is recessive, you can put black to black and if they both carry white they can produce white but white x white will only produce white.

hi mark. my friend mandy bred a litter of pups from her white bitch, to a black/tan dog with white ancestry. all the pups were black and tan, but as they got older, most of them turned a lot lighter, very sable/gold. you may get white pups, you may not. mandy expected to get some white pups, and sdidint get any. she bred a 2nd litter to the previous studs brother, and did get white pups though, but he was a half brother, so he had more white anscestry.

i thought white gsd was a gene defect?

It is simply a recessive colour gene. But because a lot of people(please note I have not written  all or the majority, before you all jump on me)who breed white GSD's do so simply for money with no HD or blood tests & no regard for the correct temperament let alone the GSD breed standard White(most are cream/biscuit coloured)GSD's can be bred from poor quality character & temperament wise. As some one who is actively involved in GSD rescue over half of the dogs that go though our hands are white/cream/biscuit in colour & the majority of them have temperament problems

For example a 8 month white puppy found straying with a choker embedded in it's neck that had to be cut out by the vet(yes it was actually under the skin)came into rescue via the vet(the Dog warden wanted "it"pts vet wanted otherwise)is fine with people but other dogs it will attack on sight from fear an example of a "rare"white GSD getting into the wrong hands & not being socialized, in our kennels as a sole house dog because of fear aggression with other dogs again a "white "GSD, another came directly from the owners home & took 6 months to get near due to acute fear of basically anything, now placed on a very remote farm with very very experienced GSD owners who have taken other poor character GSDs & bonded with them.

If people wnat a white GSD fine but me but & it's a big but they should have the same temeperament & character as a correctly coloured GSD & of course the same HD/haemophillia testing done

Most of the "white"GSD go back to a dog called Ingersohn Errol who is behind Quadrille of Eveley & Avon Prince of Alumvale-this dog was exceptionally nervous & details of him & his offspring can be found in Nem Elliots book Modern Bloodlines, Nem told the truth Warts n all in this book
