I don't know much about dog breeds but if socionics is genetic...Then really we are doing what accounts to people breeding selection for specialization. Like dog breeds are bred for certain characteristics.
The 8 information elements are just the broad vectors needed at minimum to describe the traits, 16 general categories that can overlap mathematically without interfering with one another.
Ex: LSIs are all the watchdogs and cop dogs: bulldogs, rottweilers, german shepherds etc
IEE:golden retriever? "Golden Retrievers are often used as therapy dogs due to their calm demeanor, gentle disposition, and friendliness to strangers"
Perhaps you can extrapolate some similarities and what it means. Also you can see cross specialization for jobs like so:
(Theres a million specializations in each of these but purely...)
Ti-LSI:judge, beauracrat, lawyer, mid-high ranking officer: ?specialized watchdogs
Se-LSI: Cop, soldier, sentry, guard :detection and sniffer dogs?
And getting racier for the fun of it:massage therapists, waiters, strippers, prostitutes: probably alpha SF: service dogs, show breeds
Feel free to add knowledge you have on the issue and
fill in the rest if you know them...I might later
