I am looking for a picture and name of a breed (cross-breed?) of dog. 
I saw a dog when I was driving in Los Angeles that appeared to be a
cross between a whippet and a french bulldog.  It had the lithe,
delicate body of a miniature greyhound, but with a round, smashed
little head with pointy ears like a french bulldog.  It was so cute I
almost wrecked my car.  I have been looking all over for information
about this dog -- is it available?  Is the a cross that breeders have
developed?  Does it have a name?  Mostly, I am looking for an image --
i just can't believe how cute it was!

I once saw a whippet/Boston terrier mix that had a look similar to
what you've described. Various kinds of whippet mixes are called
"Lurchers." This is not a breed, but the term might be useful to you
in your search.

Thanks Pink, I learned something early in the day!

Fascinating!  I used to own 2 retired racing greyhounds so this is
very interesting to me.
