It's not, i am from Serbia but doesn't mean i know Russian
both our languages have similiar words, etc... but i dont understand russian. I understood that in text you linked they mention name shalaika , i think i explained that Sulimov dog and shalaika are different breeds. Sulimov dog is dog with best tracking and sniffing abilities and they were selecting since 1975 and in 2002 they entered in airports to do their job...
They are working dogs !!!
