I believe there needs to be better definition of terms of "herding" and "mastiff" to give a good answer. Does "herding" related to the dogs of Great Britain (BC, Collie) - very frequently it does. We think only "herding" dogs herd. But many we don't think of as "herding" will function as a good farm dog. Judging by the many different breeds that have been created in a relatively short time, once people breed to some standard based on their particular wants, this breed standardization happens rather rapidly. It used to be working ability, now it is more based on looks - but whatever, the genepool seems quite accommodating. Anyone who routinely works the central European dogs and watches their style of work knows there is probably little relevance to the UK dogs in working/training style. I find a larger difference in working style between a GSD-BC than between GSD and Std Schnauzer. Maybe it is that "German" part of the equation???

It looks at the genetic diversity of dog DNA and its influence on dog shape/size etc. On page 47 they present a chart where the DNA of 85 dog breeds has been analyzed and clustered into four broad categories : wolflike; herders; hunters; and mastifflike. Surprisingly, the German Shepherd is shown to have overwhelmingly mastifflike DNA..almost none of the other DNA types. If this is true it sure brings into question how the breed could have been developed from German herding dogs. Interesting..what to believe, science or history?
