... But I WOULD like to point something out to you. In this statement from Caro she said that it's LIKELY they would exibit this behavior. 'Likely' dosn't meen that it's the case for everyone...
That's a good point, but if I were a betting man (I'm not, but if I were), my guess would be that this quote that Caro added caused Lunatic59's response:
"One of the puppies always becomes shy, even when both puppies started off as bold and outgoing. This is a huge problem, since it means that the shy puppy never reaches his or her potential."
I know that "always" and "never" generally hit me like a bat between the eyes. It is rare that situations "always" or "never" occur, and when I see them quoted, I usually look for additional issues in the point(s) being made. What's funny here is that I basically agree with the overall point being made in most of the Littermate Syndrome articles that I have read, I just believe that "always" and "never" statements require proof or would be better left out of the narrative.
