Hey dakar! Hope you are well.
I don't think you have to worry unless he comes over to you and pukes pea soup in your face.
He is a cute little thing though - whatever he thinks he sees, he's very serious about letting it know he's in charge!
(I know what you mean about it creeping you out though, when Veronica was young there were a few times when we were home alone at night and she was lying on the bed with me and she would just start looking into space and barking - which seriously? Thanks a lot dude.)
Now that she is older I think I can confidently say that I could be killed in my sleep and she wouldn't wake up.
