Pure frenchie or mixed?

my husband and I adopted this sweet girl a couple weeks ago from a local pet orphanage. She is 2 years old and has some liver issues, but we have been looking to adopt for some time and loved her when we met her. My parents have had both a frenchie and pug so when I saw her, she reminded me of both. The pet orphanage says she is a Frenchie but she has a long tail and coloring similar to pug.

What do you think?
