Bella is pretty fearless for the most part. The only times I have really seen her cower a little are when I have taken her to my daughter's. The neighbor on the one side has two scottish terriers that bark up a storm when they see her coming up the driveway. Bella's tail goes way down and she avoids looking at them. On the other hand, when I take her for walks if we should pass a rottweiler or german shepherd her tail wags right off her body. I think it's the barking that she finds intimidating.
