It all comes down to wording. Based on this article it looks like "smart/dumb" equates to "trainable/untrainable".
After reading this forum, though, I have a great new bit of ammunition. My She-Ra isn't intelligent at all…but she's definitely CLEVER. She's totally figured out ways to get what she wants, whether you like it or not. And I love her for it.
As far as representing the breed, the park where we walk her regularly almost always has a family checking her out (she's GREAT with strangers and kids), and you can see their eyes light up when you mention the "barkless breed". I do my part, though...I'm quick to throw in that they're VERY destructive, highly energetic, and that the fact they're petting her is a solid example that she's NOT the best representation of the breed. I explain that we love her, but we had to change our own lives and personalities to adapt to her...it wasn't the other way around. I think I've discouraged more than one potential buyer that way...but some people are genuinely still interested, so I try and bring up as much good as bad. Saw a lady with a tri-color awhile back and we swapped "war stories"...LOL.
