To the ordinary person, the distinction between a Shepherd bred in America versus one in Germany might not be apparent, but the differences are character in addition to numerous in the appearance and ability. The difference is in the angulation of the trunk and hind-quarters if one were to compare the lines with lines. American German Shepherds are bred to highlight a body.
Their build is thinner with a head and muzzles. On the other hand bloodlines have a more heavy build. Their heads are square, and their backs are sloped without angulation. In nerves, the distinction is concerning nature. Bloodlines have a reputation for producing milder dogs with nerves that are poorer. Bloodlines, DDR lines that were working and notably West German lines, are bred to have a strong desire and strong nerves to work.
The aspect is over functioning ability that bloodlines are bred as show line dogs for qualities. American show line dogs lack the balance, speed and agility while angulation and bodies may seem fine. Any competent dog is going to be bred from import working line dogs, although this doesn’t necessarily mean working line dogs can’t be bred in America. Bloodlines are bred for functioning and usefulness ability since the development of the German Shepherd in the late 1800s. The Schutzhund trials were put in place to keep to ability of the German Shepherd breed. German dogs who don’t posses the strength, agility and nerves are not permitted to breed. This guarantees that the best and brightest are created in Germany. The same can’t be said for criteria in the usa.
