"Janet Baraclough" [...] Mike Lyle
replied to my post in French and seemed to be asking me if
"she", ie Sacha, had a dog .[...]

In that case I'm glad I dropped in on a thread which had ceased to be
of interest. I used "du", not "un": it's a slang expression, and I
was punning harmlessly. "Has she got appeal?" is a reasonable, if
very lame, translation.
