jared wants a rottweiler

jared wants a rottweiler that he can walk on a chain. every time we talk about it, i like to say, "you will come home and i will be DEAD with my jugular ripped out. IF ONLY you had come home at 730 for dinner, you could have saved my life, but you didn't come home until 9 and now i'm dead."
but i am honestly afraid of rottweilers. supposedly you have to socialize them well (jared will never be home) and show them who is boss (i am not the boss of any one), so i'm pretty sure the dog will sense my weakness and kill me and the children.
but apparently they are also very devoted to children and good dogs if trained right...
so i said if we get one, can we name it tea cake? jared said no.
