One thing I hate is when there is a message in the diad that pops up saying "deliver back door" then there is a dog in the back yard! Today this happened to me... Went to the back door and as soon as I knocked on the door, 2 smaller dogs came rushing out the dog door. Nothing happened, but it could have been bad if the dogs were bigger
Yelling really loud, usually gets them out in time to know. Dont run, because you will get a warning letter. Never been bit at work, just on my own time. Got attacked trying to reign in a dalmation rottweiler at home, on my street.
Once I got over the fear, when I heard my own keys jingling, thinking it was a collar on a loose dog, I have much more confidence, and yes they sense it.
If you are fearful, and they smell it, they are on notice, something to be scared of.
My big beautiful, baby doberman, and many others I have had, restored my confidence.
