I found this:
Mignon - Female Yorkshire Terrier seen on the rural comedy series GREEN ACRES/CBS/1965-71. Mignon (as in "filet mignon") was the pet of Lisa Gronyitz Douglas (Eva Gabor), the Hungarian wife of attorney Oliver Wendell Douglas (Eddie Albert). Mignon lived on the Douglas' farm near the town of Hooterville. Other dogs on the program included a Bassett Hound named Cynthia and an Irish Setter named Quincy.
I am looking for a pic now
