I don't think you're overprotective
Those all sound like things I do! I often find myself picking my baby up when there is another dog on a leash nearby (if they look kinda scary...) I've read all the stories on here and even have been to a park where a yorkie was killed by a coyote!

I don't think there is a such thing as being too protective!
