YES!! Papillons are so named for their erect butterfly ears with
the long fringes. The drop earred, less common variety, are "phalenes,"
or "night moths." Papillons were the toy continental spaniel and are
featured in many old masters' paintings -- usually with the drop ears
and looking more like spaniels.

I've homed at least 10 over the years, usually from ages 5 to 15 or 16.
I used to take long walks with about 3 or 4 and people driving by would
stop to take pictures. They had never seen a papillon -- once a rare breed.
Not so much anymore. Our first one, in 1972, came from Canada and had
a British mother. There were only 500 registered in the USA at that time.
