What else is mixed with this lab?

I’ve been volunteering at my local shelter after my soul dog passed away just to socialize with dogs because my life feels empty without one. I have grown to love this dog and am considering fostering her. My last dog was a lab / pit mix and I’m very familiar with the needs of a lab + training/structure a pit needs so I am comfortable with those breeds. This girl definitely had lab in here and her mouth/jaw looks like a pit terrier but curious what you think she may be mixed with.
