She definitely does her rounds at night, checking that the kids are where they're supposed to be and patrolling the back yard. The storm door we got with built in doggy door was worth every penny to not have to go let them outside every 5 minutes
she's got that mean af GSD bark and she barks at anyone who walks passed our house. She also rats out the kids if they're up after lights out. Between her and our "Texas Pyrenees" (short haired LGD) I have 0 worries about anyone trying to come into our house or backyard
but then when my alarm goes off in the morning she goes into the baby's room and gently nudges her awake, then runs in the boys room and jumps on the middle boy and licks his face till he gets out of bed to get away from her
