Timidity. I see too many Welsh who are shrinking violets, or worse, just plain shy. From what I've been told it's much better than it was, but I also had a very famous lab handler say to me "A happy Welshie! You don't see a lot of those." Clearly it's still a problem in the breed. Watson isn't shy or timid at all and I want another like him.
They can be a little independent and stubborn at times, which I wouldn't mind tweaking, but it's not to the extreme.
