Well, I am from Portugal.
Here cavaliers are not very popular. They aren't unpopular, but we don't see too many.
I am also at a dog forum here, but I believe the "bad marketing" to our beloved breed prevailed, because of that documentary from BBC and the British Kennel Club ("Pedigree dogs exposed", from 200.

I believe that most people thing that most of the dogs have SM and MVD!!!!!

So, that's why I am asking for a good documentary, to post there.
If you know any, please share the link with me. I just can't stand "Pedigree dogs exposed"!!!!!!!!!
