If a farmer puts all of his livestock out into one pasture, at the end of the day he will find the sheep with the sheep, the goats with the goats, the pigs with the pigs, the cattle with the cattle.

Dogs are members of a single species, as are humans.

But some of the dogs, maybe just two in a mixed bunch of dogs, will assume leadership and become the "pack leaders." The rest will accept that leadership until one of the "pack" may fight to supplant a leader. Happens all the time with dogs (and their ancestors the wolves). My huge black Belgian sheep dog merely had to show up among other dogs and they all immediately seemed to recognize him as their logical leader. One low growl and they fell in line and stayed clear of him. Most people avoided and showed fear around him. The only people that needed to be afraid were those that tried to break into our yard and house. They left running and bleeding..
