The above dog is a Brazilian mastiff, Fila Brasileiro. There is no better guard dog rotty, dobe, gsd all mice in comparison. And u don't train them they are the most loyal family dog but will attack anyone besides who it lives with without provocation that is there temperament. There a 150lb machine used in Brazil to hunt slaves way back and hunt and kill mountain lions also herding aggressive wild bulls, I forget the name. This is the end all security dog.
Dude I've been a dog lover ally life a dog man most of my life. I know about the fila as well as the few other breeds you mentioned. You saying the fila is the best is like saying hsing i chuan is better than bajiquan or such things. So please don't mislead folks who are generally quite ignorant of most breeds especially breeds they really need to know well before buying/getting one.
Think about it hard core schutzhund competition has certain breeds you see more than others and Fila's aren't one of them. Does that mean they aren't good dogs ? of course not but it does mean professionals who count on their dogs to get it done favor certain breeds for a reason. and that fluctuation has seen some changes over the years but not many. Rotties and GSD's used to rule but it depends o n where and who had them. Giant Schnauzers used to be used quite a bit in europe but ,ost in the United Snakes haven't seen one in person in their life time. THE gsd NOW TAKES A BACK SEAT TO THE MALINOIS which is a slimmer version that's harder and faster than the GSD . when i was downtown in my area during the 911 debacle they surrounded the war memorial area. at least 90% had a Malinois. where most in the public would simply thing they were slim GSD's lol.
You described the Fila as a dog that will bite anyone except family without provocation. you seem to think that was cool but for a family dog in a normal house that dog isn't suitable with a propensity to react that way is it ? Yes, you might not see this But i write so others who are still here do see my post and think in a more reasonable and practical way.
Rotties are great protection dogs but not all of them make great family dogs for the same reason some fila's might not. Rotties that aren't well trained/socialized often have a tendency to just tolerate others outside their family//friends. they can't wait to crunch on the foll that they feel has fucked up. why though, because they have worked in dealing with men and attack/protection situations for so long it's in their DNA. you don't have to train a rottie to protect you. They will do so naturally and automatically.
APBT/PIT BULL, some will protect their home while others simply won't and they will go with the burglar if the burglar wants the dog too lol. I'm not knocking the breed because they are my favorite breed until i die but I DO KNOW THE TRUTH ABOUT THEM OVERALL. Some are territorial of their property and those dogs will protect while others couldn't give a shit about an approaching stranger to their yard/house and will visibly let you know they want attention and would like to play. Yet, the same breed has been trained in schutzhund/ring work and excelled. their handlers applaud them and speak extra highly on their [performance because these dogs love to please their owners.
Dogo Argentine great family dog and nobody is gonna like the results of an encounter should they breach the property or try to hurt friends/family.
Doberman when bred well etc. are fine in the home and safe with family as well.
Chesapeake Bay Retriever a little known monster to anybody that tries to hurt you or the kids. they are dogs that should only be gotten by experienced people they aren't a dog for novices at all.
AMERICAN BULLDOG good for family and protection. Yet, you better train them because they will get out of hand especially the males. a big johnson male will turn into a man killer if not dealt with properly. Many of the hybrids will too because more and more they are using them for protection work
so be careful who you buy one from
English Mastiff TRIED AND TRUE FAMILY DOG AND PROTECTOR OF PROPERTY AS WELL
