So I have an interesting story to tell. We have had our new "B" Cleo for about a month now. Other then a little bit of whining here and there she usually doesn't make a sound. She does seem to muster up a semi bark when there is a strange person knocking on the door. I think she is trying to protect us, lol 
Well last night something new happened. Me and my boyfriend went to bed and closed the door to the bedroom. She has the rest of the condo to herself. Quick side note, my boyfriend is a police officer. So as soon as we turned the lights our she started to bark. We knew something must have been wrong. We both jumped out of bed and my boyfriend grabbed his gun (thats what police offiicers do). As soon as we got to the living room we heard a loud argument. Seconds later we heard the guy yelling that he was going to shoot the other person and that he had a gun. I called 911 and they were already on their way. I boyfriend never got involved but it was kinda a scary situation. Thanks to Cleo we knew about before it even escalated.
After that they took the guy away and we went back to bed. Not more then a min later Cleo barked again. We jumped out of bed once again, lol. We take her making noise very seriously, because she doesn't make noise unless something is wrong. Nothing was wrong this time, but we forgot to lock the door after the whole situation was over. I guess she just wanted to make sure we were safe. I gave her lots of praise for being such a good dog. She really makes me feel safe now.
I made a joke "I guess she is like the modern day lassie. Timmy didn't fall down the well, but some guy is going to pop a cap in someones ass outside, lol"
P.S. I live in an extremely safe neighborhood. Nothing like that even happens, its usually really quiet. The most exciting things that happen are skateboarders running around, and that about it.
