New Dog Dad but of what breed?

I would say she is a lab mix of some sort. I agree with LeoRose she has that broad head of a pittie and I am thinking her face looks like a lab. Then again she looks like RonE's dog Esther. I am not sure on a good DNA test though. Most of my dogs have been pure. The mutts I have adopted or found and kept, {what can I say they were two adorable to give to a shelter} you could easily tell what breeds they were. I would find a good reliable vet, because your gonna need one for your girl anyways, and ask if they could get you a good reliable DNA test.
