Yep, French boxers are born in France, German ones in Germany, US boxers in the States... And the list just goes on. LOL - boxers are a German breed, now bred in nearly 100 countries around the world
Yes there are some people who think that boxers bred in North America are quite different from European ones. Those same people (generally) conveniently ignore the differences between boxers bred in different European countries, and boxers bred elsewhere in the world simply cease to exist or are somehow a subset of NA or Europe. LOL - can you tell it irritates me? I think it is rather ignorant.
With all that said, yes there are some minor differences in style. But that actually applies within countries as well as between countries. And the differences are generally pretty minor. Some breeders put more emphasis on elegance than on substance - but the boxer is supposed to have both

More to the point, the differences between good boxers (meaning those that fit the breed standard well) in the various countries is negligible. The differences are far more apparent in the poor specimens.
Here is a site that explains the differential between type and style very well. It also addresses the myth of significant differences between boxers from different countries (scroll to the bottom of the page for a link to a very useful article).

You could also do a search on these forums - that theory has been brought up before. Just type in 'european', 'euro' or euro-boxer' :rolleyes:
