We use to have South Russian Ovtcharkas(aka Wolf Killers), very agressive LGD breed, we could never keep more then one female without big fights(males oddly enough got along if intact), and if it wasnt "intact"(either male or female) it was killed by the others for being "sick".
Awesome breed to have, very loving to "their" people, or anything baby. Problem is they do not hesitate going for the throat of both predator and stranger who dare goe past your gate without you with them..... Altho, our South Russians appearantly were too nice for the breed because in the behaviour test in the show ring the judge took off points if he could touch the dog without being growled at. We get lots of visitors so we socialized them LOTS.
We only brought the female with us to Canada, and she was 13 at the time. Never seen her do much other then lay on the porch but after she died at 15 yrs old Coyote activity went thru the roof again.
We suffered thru it for 3 yrs before we said enough is enough and got another LGD(altho not a russian even tho my mother begged, its just too agressive of a breed for here without an 8 ft perimeter fence so she doesnt eat the joggers).
Sasha we found thru a small town newspaper driving around southern alberta looking at LGD litters.
He was 10 weeks old, Dad was a huge pure Akbash(which had to be contained first before you left the vehicle) and the mother a maremma that guards about 150 sheep.
Well, he wasnt socialzed to people at all, but we force cuddled him so to speak and he has been on coyote patrol since he was about 20 weeks old. Best dog ever, loves being in the presents of people but doesnt need the touchy feely thing. He does come in the house and demands his morning scratches from my dad ON the couch(who knew such a big white dog can curl up on a persons lap like one of those little jappy furry oversized rodents).
He is intact still, his is a quiet dominance that doesnt need more then a look to establish. Doesnt roam or anything. He isnt bonded to any particular livestock(after the sheep beat the tar out of him that relationship was over) but if we introduce it to him it seems to be part of the family and gets protected no matter what. Very much like our south russians, if you bring it onto the property and introduce it to him it must be family and is accepted, if it wanders on the place on its own it gets a bite in the rear.
Now we have an 8 month old intact male Akbash/Kuvaz/Maremma as well, since we didnt want to have war between the males again -our last bearded collie bitch we brought with us from Germany finally died last year and our neutered black lab has not picked a fight with the intact Ak/Mar since, thank goodness, that lab is a stupid bugger, picks a fight even tho he gets pinned in one quick motion by Sash every time---
Sam(the "puppy") so far has no protecting instinct(other then sitting indoors barking at noises outside), only thing he knows(and he grew up with sheep and both his parents work sheep) is that my sheep are the devil re-incarnated and avoids them as much as possible(he dared to go in their pen when I had my hands full and he got beaten to a pulp by them).
Not sure how big of a help he will be to Sasha when the time comes, he was intended as back-up since the yodel dogs come at sasha in packs of 6-8 individuals now and Sash lost part of his tail this spring in a fight with them.
They do get along great tho and he follows Sash everywhere during the day, just a chicken in the dark..... maybe he will turn into the day-shift, since he has gotten a bit more serious in the last month Sash allows himself longer sleeps(after a night shift he usually comes in to crash for a few hours every morning) under the kitchen table while sam sleeps outside.
