*EDIT: I had a lot of info posted here about Japanese wolves, but I'm going to try and rewrite it in a preferably shorter and more coherent manner, as well as gather and quote my sources more accordingly. It should also help with the keywords as this picture seemingly pops up everywhere because of the previous text wall.
Photograph of one out of two extinct Japanese wolf subspecies. This one if of canis lupus Hodophylax.
It's one of the two only specimens in Europe. There are five more in Japan. This picture is of the one located in Leiden, The Netherlands. The other one's located in London.
It was on display for a temporary exhibition where the most important pieces of the Siebold collection were shown (Siebold is the guy who collected the specimen).
I'm putting this picture up as stock in case anyone would like to use it for educational purposes. Please do give credit somewhere if you decide to use it or just link back to it somewhere.
*Edit: no seriously, please give credit somewhere, even if it's just a link back in a corner or something. I don't like doing this, but I'm going to have to paste a watermark all over it if I see it pop up uncredited any more often, which I have seen numerous times by now.
Actually, Japan has no actual “wolfdog breeds,” unless you mean dog breeds that look a bit wolfy.
A wolfdog breed indicates that the breed has been established specifically by crossing dogs and wolves in order to create it, such as the Czechoslovakian wolfdog.
As for alleged “wolf blood,” some historical reports of Japanese wolves and dogs crossing do exist, but from what I understand they were infrequent and not intended to create a separate breed of wolfdog. Native Japanese dogs have also strongly declined in numbers a few times, and a few breeds even nearly went extinct after WWII which only would've diluted it further. On top of that no new wolf blood has been added in well over a century at the very least, but probably much longer.
So any amount of “wolf blood” would've been incredibly little to begin with, and completely undetectable by now.
The first is Kumano wolf dog of Nara native.
I think you can see in the image also come, but the other day, I was taken up at any NHK Special "Miokami-ki" This breed.
I knew only the name and existence from a few years ago, I was really impressed by being first saw the figure
Kumano wolf dog to have been produced is that of Showa medium term. Kana was after the war?
It is the one that is considered to be you're left behind in the wild dogs that dog catching the blood of the Japanese wolf researcher to study the Japanese wolf, disappeared living in its habitat, was born for the first time restore using it .
It was completed in an attempt to revive the dog like it by going by multiplying what appears to be a large number capture the wild dogs to launch a cage trap to Kumanosan during, and inherited strongly the characteristics of the Japanese wolf. As well as wild dogs that were captured, hounds hunter in the vicinity are also keeping seems to have been used for the bleeding.
Dog very similar to Japan wolf finally over several decades was born, but the body is weak by nature, the child I have unfortunately died young
From what I can see (pictures) and read (historical sources/possible breed establishment), their wolf content is completely speculative, like with the other Nihon Ken.
The "wolfdog" title seems to be more of a symbolic nature.
Oh, I've heard of that breed. I think it's more commonly called the Hokkaido-Ken. There are other Japanese dog breeds which are thought to have some Japanese wolf ancestry due to their purity throughout the centuries, like the Shikoku-Ken and several breeds of Shiba. (These native breeds didn't originate from Japanese wolves; they were first domesticated on the mainland and brought over some 9500 to 8000 years ago.)
From what I understand, it's uncertain just how much Japanese wolf ancestry these breeds have. There's a lot of dispute about the differences between Japanese wolves and native dogs and about the degree they once possibly hybridized.
