Bow does not like to have strangers anywhere nearby, and it even bothers him if there are people just outside the property line whom he sees as a possible threat to our territorial integrity.
I told Bow I would go out and see what it was. Here is what I saw.
There were cows in the neighboring field, and they were a little closer to our property line than they usually get. That's all.
Fortunately, when I went back in, I was able to show Bow the footage I had shot, and he was satisfied that the cows posed no real threat to our security. All is right with the world!
