In their defense (?), I get the impression the dog awakened them and they went outside because the dog was insistent. I have not listened to the video, but that was my late night read/take on it. Then they decided to video him/her. I'm curious if the dog was leashed or unleashed.
jmo etc
I agree. It sounded strange to me at first but when I stopped and thought about it, I could easily see it going something like this:
Dog uncharacteristically goes nuts in the middle of the night.
Dog parent logically figures dog is barking at either a wild animal (anything from a rabbit to a mountain lion) OR a prowler. It may not be that unusual, due to wildlife in the area.
Dog parent decides to let the dog out, to run off prowler, if there is one. Or to let possibly dangerous animal know not to hang out so close to his house. He may also think the dog needs to "do its business" now, since dog is so worked up. It's possible (likely?) the dog is a tough guard type dog, pit bull, German shepherd, etc. Dog parent wants to send a strong message to possible prowler that he is not to be messed with. But he doesn't want to bother the police and feel embarrassed if it's only a small animal the dog is so wound up over. Calling LE could also possibly send a signal of weakness to the possible prowler, that dog parent needs to call in help. This seems to me how a lot of guys, in particular, would think.
Dog parent follows dog outside. Dog is either leashed or not but probably trusted to obey dog parent.
Dog parent uses iphone to record whatever event is unfolding. Sure, why not. Don't most of us usually have our phones with us anyway. iphone might capture image of the prowler, if there is one. Or dog parent might get some really cool footage of a wild animal (bobcat, mountain lion, coyote, javelina, owl, etc). And, of course, he can easily call 9-1-1 that way, if needed.
Also, quite possibly, dog parent has a gun with him.
Okay, I may be putting way too much thought into this lol.
MOO
