German Shepherds are ideal family dogs. The reason the dogs only listen to the one person is because they were trained that way. They can handle a plethora of owners and handlers unlike some breeds. The Dogo is a good dog but, they don't do well with social situations an if it feels stressed or cornered can attack viciously. German Shepherds if raised to be social do fine with social situations. I have mine completely attack trained and he is completely child safe. Any child can man handle him with no risk. Not so with strangers who come to the house without permission. Heaven help you at that stage.
