Speaking from my own breed perspective- if you look between the countries, Shibas are pretty similar no matter where you go. We do a fair amount of importing between countries (I know people who have shipped to Italy, and Australia, and others who have received puppies from as far away as Japan and Demark). There are *some* regional differences, but they are regional differences from the country of ORIGIN, differences that were apparent 100s of years before Shibas had left Japan- and they all still represent a correct interpretation of the standard. A slightly different fill in the cheek, a sashio tail as compared to a makio tail- these do not make the dog any less FUNCTIONAL. This is what we call a difference in *style.* The differences are so minute, it's quite obvious they are the same BREED of dog.
NO breed is going to be SO cookie-cutter that you won't see ANY variation- but when we INTENTIONALLY vary from the same standard that ALL breed clubs share (and in case of the Rotties, I do believe that no matter WHAT nation you're in, it's fairly well agreed upon that a long coat is a DQ), is when you REALLY run into problems.
Once again, I'm not talking about different interpretations of the actual standard. There are different ways to interpret a standard- that doesn't necessarily make only ONE right, and all the rest wrong. There WILL be regional variations, and that is part of the REALITY of living in a world that does NOT make it easy to ship animals from country to country. What I am talking about is INTENTIONALLY breeding DISQUALIFICATIONS. Things that are universally agreed upon as being INCORRECT. Not "a little less favored," but point blank WRONG and detrimental. You won't see anyone worth their salt breeding "teacup" Chihuahuas. Nor will you see good breeders breeding a blue merle Aussie bitch to a blue merle Aussie stud. Nor will you see good breeders intentionally breeding white Shibas.
I'm not saying that what you're talking about DOESN'T happen- of course it does. Humans are not infallible, and there are a lot of people out there that will "talk the standard" until the cows come home, and then fail to see that they aren't breeding to it. What I'm trying to get across is that it makes NO sense to use this as an excuse to deviate even FURTHER from the standard. To intentionally breed for things that breed clubs nations apart AGREE make NO SENSE.
