I don't have any experience with sarplaninacs.. so I won't comment about them. but I have seen plethora of dogs from LGD breed and I have one myself.. provided that you raise them with due authoritative ownership, love and respect, they will be very loyal to you and very soft to the family. no matter how ferocious the dog is known to be, he will be great with the family. his aggression will be directed to the strangers. so, don't worry.. but sincere request is, instead of trying to desensitize the dog from aggression towards strangers, you may pick a softer type of LGDs.. preferably a great pyrenees.. 'softer' doesn't mean less capable.. if you want a sarplaninac, essentially go for one.. it is absolutely your choice and you exercise your choice. pick the right puppy and raise it in the right way and he'll be a great companion of yours. (right way doesn't mean something which is really difficult.. it is just saying 'NO' and "good' whenever it is needed to be said. and of course, being a rottweiler owner, you must be knowing.. exercise your authority..by training or things like that..) good luck.. :D and about different levels of respect and love and devotion, see, I find every enthusiast of every breed claiming their breed to be the most loyal, devoted and loving. it is not false. they actually are so devoted. but different level means what? as compared to humans? then, on average, yes.. but when compared to other dogs, I don;t buy this statement. because I have owned so many dogs and I have found every dog to have its unique way of showing its respect,love and devotion. and they are not a monopoly of any given breed. and besides, we have seen individuals from almost all performance breeds working so hard with devotion,love and respect that they even go to the level of self sacrifice gladly.. dogs from rottweilers, GSDs, Dobermann to various breeds of LGDs have exhibited this noble trait. I don't understand by which measurement the sarplaninac has been found to have a different level of the said attributes. but I understand that it is true, and not false.. not only true for sarplaninac, but for every dog breed that exist on the planet earth. for dogs radiate pure love and devotion.
