From Wernher Gerhards, Bionics Press Center Meissen – bionic behavior biology research:
I have resolved your suggestion and went off to find a reference, because it is possible that someone anschreibt me or asks where, Professor, I can read that? In fact we had made in Stalin’s Russia large Muehe heranzuzuechten a watchdog for the gulags. For this purpose a mixture of Caucasian stove dog was used that the large, sharp and very dangerous Caucasus Sichen Owscharka spawned finally. It what THE Gulaghund but was etc used in border protection and the protection of industrial plants, as well as on the border of the GDR. http://forum.hundund.de/herdenschutzhunde/haltung-von-herdenschutzhunden-unserer-engeren-umgebung-t116290-60.html (see dogs under the Red star). For border management purposes were crossed throughout with wolves in the Tschechoslowakai Schaefer dogs because it was hoped to germination and cultivation bigger, stronger animals that were better adapted to cold and make snow. It began in 1955, heard in 1971, because the bastards for the border guards were useless because they had lost the Sharpness of Schaefer dogs and shy and scared of humans remained. ( http://chwolf.org/woelfe-kennenlernen/wolfshunde/tschechoslowakischer-wolfshund ). Something strange now follows: The Russians bred further ebefalls vain until their breakthrough in 2000 succeeded – so 29 years after the Czechs had aufgehoert. I wonder why? They discovered in 2000 ungewohlich philanthropic Woelfin, Naida. It was crossbred with Schaefer and dogs from this line the Volkosobs were then bred ( http://www.odditycentral.com/animals/volkosoby-the-wolf-dog-hybrids-bred-to-defend-russias-borders.html ). These hybrids were then the most excellent – even the silver bullet of Russichen Army austeigenden Wonder Dog (Wolf Dogs: The secret weapon of the Russian military, 05.08.2008, Spiegel Online; http://www.odditycentral.com/animals/volkosoby-the-wolf-dog-hybrids-bred-to-defend-russias-borders.html ). This Volkosobs have about 30% bigger brains than dogs are fearless, learn quickly and correctly, are quiet and therefore for secret operations ideally etc. It therefore wonders why the Russians did not follow the Czechs? I suppose that there had been former Wolfseinkreuzungen who “became ‘miracle dogs. So far as I know, heard the dogs and wolves Verkreutzen of at the Finnish border when the Komunissmus together worked in Russia. Thus, the old breeding lines were no longer there, and the Russians were on, shrewd by experience. And in 2000, it succeeded! It is thus possible durhaus which such wolf x dog hybrids were used in Communist Russia to Gulagfluechtige recapture. Read times what is written about the Volkosobs! There are indeed wonder dog! But for Gulagzwecke wuden Owscharkas bred.
