If someone would try to break into my home Eko my 75 pound GSD would meet them at the door before I was probably awake if it was at night during sleeping hours .. If anyone would like to go against her very strong bite force .. [ the bite of a German Shepherd has a force of over 1,060 newtons (238 lbf) ] they would be on the losing end .. if they were to get by her a firearm is always next to my bed or on my hip if I am up ..
