Thanks for the comment and the additional research!
I always enjoy the dog articles, too, and I was also surprised by fear of heights. It never occurred to me that a dog would experience that particular fear.
Those two links were interesting finds, and they raise good points about stress-contributions from environmental factors and the emotions of the owner. Especially when you think about working dogs that were intentionally bred to be good at interpreting human cues and performing specific activities like hunting or herding that are very different from their lives as domestic pets.
Also, I have to admit that I was (am) a little skeptical of generalizing from an online survey from a small country like Finland. It's interesting, but I'm not sure how conclusive it is, so I appreciate the additional references.
