Realy any breed can be protective towards their owners, you just have to build a special bond with the dog. Simba is very protective. I think that is because im the one thta picked him out, drove with my dad to get him and Simba sat on ym lap the whole sway home. And the first couple months i was always with him 24\7. I even slept on the fitchen floor with him just incase he had any accidents of he got scared at night.
