letter from japanese breeder about pigment of coat color

edited May 2012 in Akita (秋田犬)
秋田犬の重要な要素の一つに、色があります。赤、虎、白の基本的な3色の中で色の重視度が最も高いのは虎ですが、赤も色をおざなりにはできません。このコーナーでは、赤を中心に繁殖する熟練者が時おり陥るジレンマに少し触れてみましょう。
ベテランの皆さんはご存知と思いますが、「退化色」という表現があります。
.
.
「良い色の赤が生まれなくなった」と感ずることはないでしょうか。
適度な赤ではなく、俗に「焼け赤」と呼ばれる濃い赤や、逆に薄い赤になった場合、「退化色」と呼びます。

ではなぜ、誕生した子に退化色が出るのでしょうか。赤の子犬が数頭生まれ、そのすべてが退化色だったとします。父母の血統書を隅々までご覧ください。赤同士の交配を繰り返してきませんでしたか。当地の大ベテランは、こうアドバイスします。「赤同士だけの交配を続けると、退化色の子が生まれる可能性が高い」。


では、どうすれば適度な赤に戻せるのでしょうか。研究熱心な赤専門の繁殖者は恐らく、解決策を提示できるでしょう。しかし、漫然と繁殖してきたオーナーは、数十年の繁殖経験があっても、回答にたどりつきません。
答えは、1度白を入れること。つまり、白と交配することです。白を1度交配したからといって100%退化色が改善されると断言はできませんが、適度な赤が生まれる確率は俄然高まります。

当地、大館市で開かれた本部展会場で、ベテラン同士らしい他県の方々がこんな会話をしていました。ある人が、出陳中の犬を見て「濃い赤だなあ」と言いました。それに対してもう一方が、「今は色が薄くなる傾向がある。あれぐらい濃い方がいいんだよ」と。はたして、そうでしょうか。濃いも薄いも退化色という点では、五十歩百歩です。「あれぐらい濃い方がいい」という考えを持つと、濃色を作ることを良しとしてしまいます。犬質向上のためにも、濃くもない薄くもない適度な赤を作出するよう心がけたいものです。

最後に、適度な赤の秋田犬を、写真(下)でご紹介しましょう。
この犬は色だけではなく多くの点で優れており、何人もの審査員から「本部展に出陳すれば、名誉章の筆頭で名を呼ばれるのになぜ出さないのですか」と残念がらせている、秋田県が全国に誇る傑作です。色は無論、全身からにじみ出る風格をご覧ください。

you can google translate this letter.

It's about Degradation of color for red akita. Degradation of color= too dark red(burnt red) or pale red( too light). and you will get this color of puppy if you use redxred breeding for all generation. and way to fix is introduce white color to your breeding to correct the color of red to moderate red.

I don't read japanese but tried to figure it out. lol

  • Interesting! That is also true with red x red Shibas over too many generations, only we re-introduce black and tan instead of white.
    Usually a dog can't be red enough. When you say burnt red do you mean brown red? I wonder if adding white to Shibas would be one way (of many) to resolve the brown reds that are so common?

    Here's the google translate of the above letter, so folks don't have to do it themselves.

    One of the key elements of the Akita dog, there is a color. The highest degree of importance of color in three basic colors red, tiger, white tiger is, in perfunctory and red color can not be. In this corner, let's touch a little with a dilemma to those skilled in the breeding center occasionally fall into the red. But I think everyone is a veteran you know, there is the phrase "degenerate color."

    Kanzuru thing as "no longer is born of good color red" or will not. If it becomes dark red or pale red called red rather than moderate, and "burnt red" Folks, on the contrary, it is called a "color degeneration."

    What color comes out degenerated into a child was born, why does. Puppies are born red head number, and then it was all of them degenerate colors. Please see every corner of the pedigree of the parents. Did not have repeated crossing between the red. Large veteran of this area, will advise this. "If you continue mating only between the red, could be born a child of the color degeneracy is high".

    So, what can be returned to a moderate red to do. Enthusiastic research professional breeders red is probably a solution can be presented. However, the owner has been breeding loosely, even if there are decades of breeding experience, does not reach to the answer. The answer is, putting the once white. That is, crossed with white. Although you can not affirm to be improved 100 percent just because degeneration color were mated once white, red a moderate probability increases suddenly born.

    Exhibition was held at the venue headquarters here, in the city of Odate, among people of other provinces veteran apparently had a conversation like this. People have, at the sight of the dog in the Shutchin said "I wish it dark red." The other is, "Which is it today is better dark colors tend to become thinner. About it" and against it. Sure enough, or will be. In terms of degeneration even thinner dark color is a fine line of distinction. Will you and with the idea of ​​"dark about it better," and good to make a dark color. Also to improve the quality dog, you want to try produced a reasonable no thin red no darker.

    Finally, let's introduce (bottom photo), the Akita dog of moderate red. Let while shame this dog is superior in many respects not only the color, "If Shutchin exhibition headquarters, Why do not out why to be called a name in the lead of the mark of honor" from the judges of any person and that is a masterpiece, Akita Prefecture boasts the country. Color, of course, please refer to the style oozing from the body.


    This letter and a number of other articles can be found on http://translate.google.com/translate?hl=en&sl=ja&tl=en&u=http://hachiko.jp/ I found it while googling for "焼け赤" "秋田犬" ("burnt red" "akita inu")
  • thanks claire
  • Yet so many breeders spam Red X Red over and over again. It's funny, after the Akiho show, I sent a bunch of photo to Mr. Kuwabara. (Mr. Kuwabara wrote "Basics of the Akitainu".

    He mentioned the dark red color as well. "In viewing your photos, I am pleased to see that the face and color have improved since the time I was a breeder. It is interesting to see that the red coat is becoming a deeper red, which is good. But some of the photo the red coat was yake aka (literal translation meaning burnt red) which is not good."

    It appears that there is balance between too red and not red enough.
  • Sean, I like that yake aka sounds a bit like "yucky aka" ... lol
  • Not sure about breeding white in to improve red. Never heard of it in NIPPO, and all the kennels/judges I asked about it thought it was ridiculous. But if it works for this breeder...
  • Nippo uses black tan to darken the red. Shiba and Akita are kinda different.^^ breeder use red to brindle litter to improve expression. and they also use brindle to red litter to improve coat thickness. and white to improve colors of red. ^^
  • Well, I have heard only 1 Shiba breeder ever say that NIPPO breeders use cream to improve red. No one else agrees with her though since she is kinda nuts
  • "Improve" is relative here, since it depends on whether or not the red is too light or too dark. White can lighten red, brindle can darken it. Just something to be aware of if your dogs are getting too far one way or another I guess.

    Sean, was Mr. Kuwabara basing his opinion on your over-saturated photos? lol! ;)
  • Yes - that camera really pops them out.
