Calculation of Wolf blood?
So I was sent a link calculating Luna's pedigree in terms of percentages.
http://www.wolfdog.org/php/modules.php?op=modload&name=WolfdogDB&file=wright& lan=eng&wid=12489&maxdepth=10 According to this calculation, she has almost 30% wolf blood. Is this true? It seems a bit high for a vlcak so many generations away, with so many GSDs in the foundation of the breed. I would think her actual inheritance of wolf blood would be about 3% at most? How is this calculated? And at this point, is the percentage of wolf blood even applicable as they are no longer a "hybrid"? |

But CsV was not breed like AWD, as allot of ( CsV ) and ( Hybrids ) was mix whit each other (and also whit wolf.) You can se here on Blood line nr 4, GSD is not used at all... Quote:
Look at "Shortest distance" to Wolf, it say 7 generations. Look at "Shortest distance" to GSD, it say 8 generations. One must also remember if you mix 30% CsV to 30% CsV the puppy´s will be 30 % to, but one more generation from wolf.... 30+30=60/2 = 30% wolf blood but as in AWD, if you mix whit dog that has 0% wolf blood, it will look like this... 50% hybrid X dog 0% = 50+0=50 /2 = 25 % wolf blood. But remember it is just mathematically and the breeding selection and generations make a AWD at 25% and CsV on 25% not the same thing, as it might be 7 generation of selection on CsV but only 2 on the AWD.

Hello Lunas Mom,
Wolfblood percentage is just a mathematical thing as Mikael just explained and you can read a lot about it in f.e. http://www.wolfdog.org/forum/showthread.php?t=8749 which Rona quoted. The mother of your dog has a mathematical wolfblood percentage of 27.48%, see: this link The father of your dog has a mathematical wolfblood percentage of 29.17% see this link So theoretically your dog has a wolfblood percentage of (27.48% + 29.17%) / 2 = 28,32% , which is about the average (about 27 - 28%). Doesn't say a lot (almost nothing) about the level of wolfish characteristics. Last edited by buidelwolf; 04-06-2010 at 18:50. |

Thank you very much for the info. I read the thread you referred me to, and it seems the "conflict" in my mind is the "American" way of looking at "wolf blood" percentage and the early breeding selection in the CSV.
At this point, the CSV is considered a DOG so the idea of it having wolf blood is no different than any of our other breeds as they are all, technically, descended from wolves. I guess the idea is to explain some of the unique traits seen in the CSV versus dogs that are farther removed from wild ancestry. |

Of course when I discuss it with people, I do tend to say, based on the "American" way of looking at wolf blood, that Luna is really no more than about 3% "wolf"... for me, I sort of think of "wolf blood" as "pure wolf blood" - once there is a mix, even though it has a percentage of wolf blood, it is still a mix, so I think of "wolf blood" as the amount of "pure wolf" in her.
It also reinforces to the public that she is NOT a wolf-hybrid, she is a dog and 3% sounds "friendlier" to them and 30%. Most of the time I tend to describe the vlcak as a breed that "looks like a wolf, acts like a shepherd." People are more likely to interact with her when they think she has little to no wolf in her - initially they suspect she is a hybrid and stay away, but when I describe her as a DOG that just happens to look wolfy they want to pet her. |

I guess that at this point of development of the breed, and after so many generations from the last pure wolf, they should be considered DOGS. They may be a “difficult” and peculiar breed, yes, but they are still dogs. And if we actually portrayed them as such, there would be many less fanatical people getting them because they want a “wolf”. I think that it would have been better for the sake of the breed if it’s name was “Czechoslovakian Shepherd” instead of “Czechoslovakian Wolfdog”, but this is of course just a personal opinion Last edited by Fede86; 09-06-2010 at 11:01. |

Lunas Mom, take a look at Belyaev (foxes) and Tryon (rats) works about effects of selection, it would help to relativise this %.

So it seems.... if wolf genes evaporated, then GSD must have disappeared as well... I wonder if there are still any genes in our dogs?

I really wouldn’t know, I’m not an expert in genetics… I guess that a breed has the genes that are passed with the breeding: the genes bringing the traits you breed for are passed, the others are lost. Since in the beginning they bred for character more than for wolfy appearance, it wouldn’t surprise me if the genes of the German Shepherd had taken the upper hand. This matter makes me curious, I think I should test my dog and see, but I’m not really expecting to find much wolf blood in him. Then again, maybe I’m wrong… I’m just wondering, since I can’t see much wolf in the AVERAGE Czechoslovakian wolfdog. Of course there are exceptions

Well, personally I don't really care how wofish my dog is or what her genotype is..., but... WHY, in your opinion, do CSV play wolves in films? I bet it'd be much easier to train a GSD than a CSV to act wolf.... |

Fede, indeed you are talking about "Wolves genes" (not Wolfblood -which is just a math number-).
You know wolves and dogs are very very close regarding DNA sharing, and sometimes only a very little change in the genome may lead to huge structural/functionnal changes, so it's not expectable to be mesured lineary (like a %). Those kind of researches are rather new and are possible with use of DNA chip + computer analisis, you can make a google search with these words to go deeper: "Genome wide SNP haplotype dog domestication". To complicate more, genes tend not to work alone but into what we call a 'genetic regulatory network' (GNR), this is also highly non linear processes. And in addition, you have other levels of regulation at "expression time" (ARN modulation by proteines is an exemple) => same genes -> different expressions. So, as you guess, no straight conclusion like this possible.

Statistically, I was looking at the number of GSDs and wolves that were used as foundation stock for our breed. 48 GSDs and 5 wolves. 5 is not 30% of 48.
Also, per one of the above posts, as the "best of the best" of the CSVs were selected to be bred, likely it was an overwhelming amount of GSD genetics that were selected for. Yes, they look very wolfy (though a lot of GSDs do too) phenotypically, most "wolf" behavioral characteristics were selected AGAINST - such as flight response, shyness, nervousness, independence, etc. Most of the desireable behavioral characteristics that were selected FOR were GSD traits - courage, biddability, social/pack drive, etc. The wolf and dog genome are almost identical as dogs, obviously ARE wolves - albeit domesticated. Our advantage is that we know what wolf blood we used, and there may be some DNA characteristics (mitochondrial or other) specific to our Carpathian wolves. Certainy there are differences morphologically. So perhaps in the future we can recognize those markers and determine EXACTLY how much "wolf" is in any given CSV. Until then I will just enjoy my DOG. Oh, just because CSVs are often used to portray wolves, doesn't necessarily mean they look exactly like wolves... here in the U.S. I know of many film shots of "wolves" are played by sable GSDs, Malamutes and sometimes even Belgian shepherds! I am hoping that having a CSV available for film work will help change that, as my own dogs have been in multiple film projects - in other roles of course - they've played Police K9s or guard dogs and even "crippled" dogs in need of a doggie stroller... |

I found out that not many of the so-called 'ordinary people' (i.e. not dog lovers) see the wolfishness of our dogs. Most expect a dog on a leash and they see a dog. It's usually children, who say: 'Look, this dogs looks like a wolf".
In our city lives a man who owns (probably illegallly) a real Carpathian wolf, a truly beautiful animal called Burek. I met them once walking at the river. We started talking and the man told me I was the THIRD (sic!) person in five years who recognized Burek was a wolf. I asked him if he was not afraid that I'd report him, but he laughed and said that in such a case he'd tell the City Guards or Police that Burek was a CSV without a pedigree and nobody would question that. And now a question: a dog or a wolf? Last edited by Rona; 09-06-2010 at 20:09. |

Good answer! It's a CSV
