I have a feeling the dad was a mix of a few breeds too. I'd tentatively say the coloring is comming either from a rottie or a dobie but there isn't much of either when it comes to her face or body yet (leaning towards the dobie due to the pointed tips of her ears). When she's full grown you may have a better idea. I think the other breeds (especially the lab) took over a little more in the way she's made up. Keep the pics comming as she gets older
She sure is a cutie! It is pretty crazy how, in the pic of her beside the dobie puppy, her chest and leg markings are pretty much identical!...besides the little bit of white...weird
