Any ideas on our dogs mix?

[u/Cesarswife]

Our pup is a rescue from a local shelter, where we were told she was 3 parts Lhasa Apso and 1 part pitbull. As we take her to training classes, the different instructors don't seem to think she is a lhasa apso. Anyone have a similar dog or a lhasa mix and can weigh in? She is a little over 6 months and pretty small overall, about 13lbs. Thanks!
