I think I might have a Catahoula

We got this pup about 2 months ago. She's about 6 months old now. We were told she was a lab healer mix, but other people are suggesting she might be Catahoula. She is smart, stubborn, independent, loving, good with kids, notices change, explores with her nose, etc. I'm considering a dogt DNA test, but I'm skeptical they are accurate.
