As you are on the FB forum I presume that one parent must be a Frenchie, and the other one something with lighter bone. As crossbred dogs can resemble either parent, a combination, or even neither of them, it really isn't possible to guess at what the other parent is. She looks a nice youngster though, and you could always get a dna test done to confirm what you have been told - if you wanted a definite answer. I thought she had a Boston Terrier look to begin with, but I now see that she is much taller than that.
