Neither of mine are 'soft' either.
Revel is certainly the more sensitive of the two, in that you can tell him off (not that I ever do of course

) and he will take notice and he does have issues with thunderstorms.
Yogi is much tougher, although during the last year he does seem more concerned about angry raised voices - just not when they're directed at him. Part of his problem is you simply can't tell him off.
My friend's beardies though are very sensitive. She had one at club when it was about a year old and a pile of chairs fell down - not a massive noise - but the dog has never forgotton it and is always really wary of coming into the hall - 10 years later!!

I think beardies are well known for having phobias etc. Love them as I do, I personally could not cope with a dog having so many issues. I enjoy being able to take my dogs anywhere - towns, steam trains, country fairs etc. A few years ago I went to a steam fair with them and was so proud, all these whistling, clanking machines and they didn't turn a hair, didn't even worry when I had a ride in a helicopter!!
However, I have come across shelties who have been traumatised for life by something fairly incongrous happening at a show - with the result this has affected their show ring career forever. Whether this was due to insufficient socialisation giving them a lack of 'coping' ability or simply nervousness I don't know but I certainly agree that whatever the other faults, the temprement of any dog used for breeding should be 100% sound. I often think it is a great pity that here, the vast majority of shelties are either 'show' or 'performance' and there are very few stud dogs who have proved themselves in anything other than the show ring. Something I would love to see change in the future.
I know in the early days shelties had a reputation for being scared of their own shadows and temprement has improved so much, it would be a great pity if things were to revert again.
